Starting with 1.47, changes marked with SYSLINUX, PXELINUX, ISOLINUX
|
|
or EXTLINUX apply to that specific program only; other changes apply
|
|
to all derivatives.
|
|
|
|
Changes in 6.03:
|
|
* chain: Fix chainloading on 6.02 (Raphael S. Carvalho).
|
|
* core: Do not leak the __lowmem and __bss16 macros to modules;
|
|
hide them so modules will not use them.
|
|
* load_linux: Do not use size heuristic for non-relocatable
|
|
kernels, for zImage kernels and for non-Linux kernels.
|
|
* PXELINUX: Fix the SENDCOOKIES feature for HTTP
|
|
(Russel Santillanes).
|
|

|
|
(James Buren).

|
|
(Sylvain Gault).
|
|
* Fix hand over to kernel:
|
|
"Booting kernel failed: Invalid argument" error.
|
|
* ISOLINUX: EDX, LBA values higher than 65535; work around for
|
|
buggy BIOS, where the system would hang, would reboot, or
|
|
would show a "Disk error 01, AX=42" message.
|
|
* core/legacynet: Enable dot quad resolution (Gene Cumm).
|
|
* diag/geodsp improvements (Gene Cumm).
|

|
|
specially relevant for older hardware and/or buggy BIOS.
|
|
* poweroff.c32: Fixes (Gene Cumm).
|
|
* HDT: Fix memory leak in CLI (Felipe Pena).
|
|
* ACPI: Remove memset of buffer; it makes things clearer but
|
|
also prevents some compilation warnings (Erwan Velu).
|
|
* Add manpages for isohybrid, memdiskfind
|
|
(Peter Jones, Gene Cumm).
|
|
* ISOLINUX: Experimental Rock Ridge support (Thomas Schmitt).

|
|
* Filesystem UUID to SYSAPPEND bit 0x40000 for FAT and ext2
|
|
(Serj Kalichev).
|
|
* Makefiles: Export the firmware type as a cpp variable.
|
|
Additional improvements. Fix "make spotless".
|
|
* core, BIOS: Move __syslinux_shuffler_size to assembly.
|
|
Actually get the shuffler size sanely. Fix booting recent
|
|
Syslinux versions on certain hardware and on certain
|
|
virtualization software (e.g. QEMU 0.11.1, VirtualBox 4.1.x).
|
|
* lua: Upgrade to v.5.2.3 (Ferenc Wágner) and additional fixes.
|
|

|
|
* core: Avoid initializing the cache more than once
|
|
(Raphael S. Carvalho).
|
|
* NTFS: Handle fragmented $MFT file (Andy Alex).
|
|
* BIOS: Use int 0x16, ah=0x02 to probe for shift flags. Attempt
|
|
workaround for USB keyboards not responding at boot time.
|
|
* kbd: Getting the keyboard shift state is now a firmware method.
|
|
* kbd: Fix force-prompt features.
|
|
* BTRFS: Fix booting on BTRFS.
|
|
* cache, btrfs: Provide a general cached read routine.
|
|
* NTFS: Correct file->offset usage in ntfs_readdir (Andy Alex).
|
|
* New support for UFS/FFS (UFS1/2) (Raphael S. Carvalho).
|
|
* adv: Remove double definition;
|
|
it should fix uses of the ADV, including "--once".
|
|
* memdump: Remove old obsolete COM16 binary.
|
|
* isohybrid: Numerous fixes (Thomas Schmitt).
|
|
* chain.c32: Add an adjustable "strict={0,1,2}" flag, improve
|
|
error reporting (Michal Soltys.)
|
|
* lpxelinux.0: Workaround for various buggy BIOSes (Gene
|
|
Cumm.)
|
|
* PXE: Fix a stack-smashing bug which broke a large number of
|
|
systems.
|
|
|
|
Changes in 6.02:
|
|
* efi64: Add support for booting 32-bit kernels.
|
|
* efi: Use the EFI handover protocol when booting kernels if
|
|
available.
|
|
* Fix various make targets that became broken when switching to
|
|
per-firmware object directories, including 'make install' and
|
|
'make netinstall'.
|
|
* efi: Improve handling of packet loss in UDP stack.
|
|
* tests: Introduce a new regression test framework designed to
|
|
ensure bugs are not reintroduced once fixed.
|
|
* efi: Implement localboot support.
|
|
|
|
Changes in 6.01:
|
|
* efi: Mark some symbols as __export otherwise libcom32.c32 and
|
|
vesamenu.c32 will refuse to load.
|
|
* bios: Wire up the bios kernel loader. It was impossible to
|
|
load a kernel from bios in 6.00.
|
|
* efi: Fix 'make installer'. There are no EFI installers so
|
|
don't try and build them as we run into build errors.
|
|
* efi: Reuse the initial TFTP client port in subsequent
|
|
transfers otherwise the server will send an error packet.
|
|
* efi: Some firmware will not set a default TTL value in IP
|
|
packets - we must explicitly set it ourselves otherwise a
|
|
value of zero may be used.
|
|
* bios, font: Fix a font regression affecting some VirtualBox
|
|
users.
|
|
|
|
Changes in 6.00:
|
|
* Add support for booting from EFI.
|
|
* EFI TCP/IP support. This allows the EFI backend to hook into
|
|
the generic TFTP, HTTP and FTP functionality.
|
|
|
|
Changes in 5.11:
|
|
* Dynamic debug support: Add new module, debug.c32, that allows
|
|
debug code to be dynamically enabled and disabled at runtime.
|
|
|
|
Changes in 5.10:
|
|
* PXELINUX: An entirely new network implementation based on
|
|
the lwIP embedded TCP/IP stack. As a result, plain PXELINUX
|
|
can now support HTTP and FTP without gPXE/iPXE. ls/readdir
|
|
functionality is supported over HTTP with an indexing
|
|
webserver, or over FTP with most common FTP servers. For the
|
|
new network stack use lpxelinux.0. For the legacy stack use
|
|
pxelinux.0.
|
|
* Rename the "ipappend" option to "sysappend" ("ipappend" is
|
|
still accepted as an alias) and make it available for all
|
|
derivatives. Add additional strings derived from the system
|
|
DMI/SMBIOS information if available.
|
|
* "sysappend" strings are also sent as http cookies, with the
|
|
prefix _Syslinux_ added, on all http transfers. This can be
|
|
overridden with the SENDCOOKIES configuration file command.
|
|
* poweroff.c32: A new module to power off a system via APM. It
|
|
replaces the poweroff COMBOOT module (Sebastian Herbszt).
|
|
* PXELINUX: Fix booting with DHCP options 209 and 210 which was
|
|
broken in 5.00.
|
|
* Handle loading kernel images with no protected mode code. A
|
|
legitimate kernel image can consist solely of real-mode code.
|
|
The support for booting such images was broken in 5.00 (Josh Triplett).
|
|
* Fix a regression in the .psf font file loader introduced
|
|
in 5.00.
|
|
|
|
Changes in 5.01:
|
|
* txt/: A new AsciiDoc documentation set (work-in-progress)
|
|
(Gene Cumm).
|
|
* core: Fix a bug in the realloc() implementation that caused
|
|
machines to appear to run out of free memory.
|
|
* ldlinux: Fix multiple buffer overflows in cmdline parsing
|
|
code that resulted in files failing to run and cmdlines
|
|
being truncated.
|
|
* core: Fix debug build by tagging __bad_SEG() with __export.
|
|
* com32: Restrict library filenames to 8.3 format.
|
|
* EXTLINUX: Fix installation and subdirectory patching.
|
|
* ISOLINUX: Fix booting isohybrid images that are over 32K.
|
|
* com32: Strip modules to reduce their size.
|
|
* XFS: Implement directory block cache and fix
|
|
shortform-directory lookup (Paulo Alcantara).
|
|
|
|
Changes in 5.00:
|
|
* com32: Switched from the COM32 object format to ELF as it is
|
|
a much more powerful format that allows undefined symbols to
|
|
be resolved at runtime and dynamic loading of module
|
|
dependencies, which means modules now become shared object
|
|
files instead of statically linked binaries - reducing both
|
|
disk space and runtime memory consumption.
|
|
* core: Split non-core functionality into ldlinux.c32, which
|
|
is an ELF module loaded by the core that contains everything
|
|
the core doesn't require to boot the system, e.g. config
|
|
parser, command-line interface, etc.
|
|
* Replaced __intcall() calls with direct function calls now
|
|
that we can resolve undefined symbols at runtime, thanks to
|
|
the ELF object support. Now that we no longer need to go
|
|
through the 16-bit interrupt mechanism we can make full use
|
|
of the 32-bit execution environment. This change required
|
|
reimplementing lots of the 16-bit assembly code from core/
|
|
in C.
|
|
* com32: __com32.cs_bounce is gone now we always run in a
|
|
32-bit environment once we execute ldlinux.c32.
|
|
* ldlinux: A new "PATH" directive was added to the ldlinux.c32
|
|
config parser that specifies a colon-separated list of
|
|
directories to search when attempting to load modules.
|
|
* ALL: Delete all references to/code for 16-bit COMBOOT files.
|
|
COMBOOT files (.cbt and .com) are no longer supported under
|
|
Syslinux.
|
|
|
|
Changes in 4.07:
|
|
* EXTLINUX: fix crash caused by dereferencing garbage pointer.
|
|
* Plug memory leak in searchdir which eventually leads to an
|
|
observable hang (Shao Miller).
|
|
* ISOLINUX: fix bug triggered by isohybrid images larger than
|
|
32K which results in an invalid image checksum error.
|
|
* menugen: make it Py3k compatible (Paulo Alcantara).
|
|
|
|
Changes in 4.06:
|
|
* Support for NTFS, by Paulo Alcantara.
|
|
* EXTLINUX: more robust device detection, allow user to override.
|
|
* kontron_wdt.c32: Add a new module to enable the hardware
|
|
watchdog of some Kontron boards. It allows enabling the watchdog
|
|
and then booting a given image.
|
|
* HDT updated, and now can display images regarding some detection
|
|
steps. Add postexec command to run a particular entry after
|
|
HDT's execution, add silent option and various fixes.
|
|
* ifcpu.c32: Detect hypervisor presence.
|
|
* lua.c32: Add dhcp support and support for native Syslinux
|
|
functions syslinux_config(), syslinux_ipappend_strings() and
|
|
syslinux_reboot().
|
|
* isohybrid: Workaround for various EFI systems.
|
|
* pxechn.c32, a PXE NBP chainloader. More versatile alternative
|
|
to pxechain.com and resolves the PXELINUX -> WDS issue with
|
|
Microsoft Windows Server 2008R2 (Gene Cumm).
|
|
* btrfs: Fix booting off of a subvolume.
|
|
* com32: Add device tree support.
|
|
* SYSLINUX: Fix relative paths for VFAT. The CONFIG and APPEND
|
|
directives now support entirely relative paths.
|
|
|
|
Changes in 4.05:
|
|
* HDT updated, and now supports uploading data to a TFTP
|
|
server.
|
|
* ISOLINUX: remove the .img file support; it has been broken
|
|
on virtually all systems since the beginning, and has been
|
|
totally broken since 4.00 at least. Use MEMDISK instead.
|
|
* chain.c32: Support chaining ReactOS' FreeLdr (Shao Miller)
|
|
* isohybrid: -m option to add support for Mac EFI booting.
|
|
* ifmemdsk.c32: Choose boot option based on presence of
|
|
MEMDISK.
|
|
* Remove bogus distributed mk-lba-img binary.
|
|
* The Syslinux project has a new, cool logo by Abi
|
|
"ixxvil" Rasheed (doc/logo/*).
|
|
|
|
Changes in 4.04:
|
|
* PXELINUX: Fix handling of unqualified DNS names.
|
|
* PXELINUX: Fix timer bug when PXELINUX might be unloaded
|
|
(Gene Cumm).
|
|
* core/writedec.inc: Fix duplicate declaration and overflow
|
|
(Gene Cumm).
|
|
* GCC 4.5 fixes.
|
|
* sample directory: Fix Makefile include (Gene Cumm).
|
|
* ver.com: New universal DOS/COMBOOT application to display
|
|
version information (includes DRMK) (Gene Cumm).
|
|
* rosh.c32: updated; Using getopt() for internal commands to aid
|
|
parsing options; Fix bugs in ls; add warm reboot and echo
|
|
(Gene Cumm).
|
|
* com32: fix a file descriptor leak.
|
|
* gfxboot.c32: handle TEXT..ENDTEXT; error out on no LABELs
|
|
found (Sebastian Herbszt).
|
|
* Fix booting on non-partitioned devices.
|
|
* MBR, isohybrid: Workaround for a BIOS issue on Acer
|
|
Travelmate and possibly other machines.
|
|
* COM32: Adding ACPI parsing libary
|
|
* HDT: Release 0.4.1 to support ACPI parsing,
|
|
improved mutli-core/cpu reporting
|
|
* LUA: Updating to 5.1.4-2
|
|
* SYSLINUX: core/diskstart.inc: Reset DS after checksum in case
|
|
it isn't 0 (Gene Cumm).
|
|
* win64: Script update for additional mingw compiler names
|
|
(Gene Cumm).
|
|
* diag: New directory for diagnostic-related tools. Add a
|
|
handoff MBR/VBR and geometry display images (Gene Cumm).
|
|
* MEMDISK: use "mem=" parameter to mark available memory above
|
|
this point as reserved (core already does alignment) (Gene Cumm).
|
|
* MEMDISK: Additional disk probe checks and debug output
|
|
(Shao Miller, Gene Cumm).
|
|
* gpxe: add gpxelinuxk.0, based off of undionly.kpxe + new
|
|
script (Gene Cumm).
|
|
* isohybrid: install the isohdpfx*.bin/isohdppx*.bin files to
|
|
make isohybrid images in one step with GNU xorriso.
|
|
* PXELINUX: disable a hack that would make localboot work on
|
|
some machines, but break just about as many. Some machines
|
|
which worked with "localboot 0" in previous versions may
|
|
need "localboot -1" in this one. If you have a machine
|
|
which requires "localboot -1", a copy of the dmidecode
|
|
or sysdump output would be appreciated.
|
|
* Include a set of diagnostics by Gene Cumm.
|
|
* Fixes for gcc 4.6 and binutils 2.21.51.
|
|
* chain.c32: Allow "uuid" as a synonym to "guid".
|
|
* Handle directory names starting with .. for vfat and
|
|
iso9660.
|
|
* New MENU HIDDENKEY command to provide a one-keystroke way to
|
|
activate a boot option from a hidden menu intro screen.
|
|
|
|
Changes in 4.03:
|
|
* Don't hang if no configuration file is found.
|
|
* Better support for booting from MBRs which don't pass
|
|
handover information.
|
|
* EXTLINUX: Try to be smarter about finding the partition
|
|
offset.
|
|
* chain.c32: support chainloading Dell Real Mode Kernel (Gene
|
|
Cumm).
|
|
* chain.c32: fix booting in CHS mode.
|
|
* rosh.c32 updated (Gene Cumm).
|
|
* Fix the -s option to the syslinux/extlinux installer (Arwin
|
|
Vosselman).
|
|
* isohybrid: fix padding of large images (PJ Pandit).
|
|
|
|
Changes in 4.02:
|
|
* SYSLINUX: correctly handle the case where the -d option is
|
|
specified with a non-absolute path, i.e. "syslinux -d
|
|
syslinux" instead of "syslinux -d /syslinux".
|
|
* ISOLINUX: recognize the directory names /boot/syslinux and
|
|
/syslinux, and the filename syslinux.cfg in addition to the
|
|
isolinux-specific names. Thus, "syslinux.cfg" is now a
|
|
generic name, whereas "isolinux.cfg" or "extlinux.conf" is
|
|
specific to different derivative.
|
|
* chain.c32: support setting alternate config filename for
|
|
stage2 of GRUB Legacy (Gert Hulselmans).
|
|
* whichsys.c32: execute specific command, based on Syslinux
|
|
bootloader variant (Gert Hulselmans).
|
|
* lua.c32: a lot of new bindings added to the "syslinux"
|
|
namespace: VESA, PCI, DMI, kernel loading (Marcel Ritter).
|
|
* btrfs: print a comprehensive error message if compressed or
|
|
encrypted files are encountered (neither is currently
|
|
supported.)
|
|
* SYSLINUX: mtools installer: honor TMPDIR, error out on disk
|
|
full.
|
|
* Handle fallbacks from EDD to CHS, to deal with systems which
|
|
announce EDD support but don't actually have it.
|
|
* SYSLINUX: the mtools, DOS and win32 installers now use the new
|
|
command line options.
|
|
* PXELINUX: fix the use of IP addresses in TFTP :: or tftp://
|
|
host syntax.
|
|
* SYSLINUX: experimental Win64 installer (syslinux64.exe).
|
|
|
|
Changes in 4.01:
|
|
* ISOLINUX: fix initialization on systems which don't zero
|
|
low memory.
|
|
* SYSLINUX/EXTLINUX: fix handing of disk read retries in
|
|
EDD mode.
|
|
* ISOLINUX: change the initialization sequence to avoid
|
|
problems with certain (old) BIOSes. Special thanks to
|
|
Helmut Hullen for invaluable debugging support.
|
|
* ifplop.c32: new module which detects if the PLoP Boot Loader
|
|
already has booted a CDROM or USB drive (Gert Hulselmans).
|
|
* Correct a severe memory overwrite bug, triggered primarily
|
|
when selecting a very long command line in the menu system.
|
|
* lua.c32: Lua script interpreter, currently experimental
|
|
(Alexey Zaytsev, Marcel Ritter, Geert Stappers).
|
|
* PXELINUX: new option IPAPPEND 4 to append the system UUID to
|
|
the kernel command line.
|
|
* PXELINUX: display BOOTIF and SYSUUID at startup time, and
|
|
when Ctrl-N is pressed on the command line.
|
|
|
|
Changes in 4.00:
|
|
* Major code base changes; all filesystem rewritten in C.
|
|
This work was done primarily by Liu Aleaxander (Yuanhan Liu).
|
|
* EXTLINUX: btrfs and ext4 support. btrfs support was done by
|
|
Alek Du of Intel.
|
|
* EXTLINUX is no longer a separate derivative; extlinux and
|
|
syslinux both install the same loader (ldlinux.sys); for the
|
|
Linux-based installers the extlinux binary is used for a
|
|
mounted filesystem; the syslinux binary for an unmounted
|
|
filesystem.
|
|
* When loading a new configuration file with the CONFIG
|
|
command, one can now also specify a new current directory
|
|
with an APPEND statement.
|
|
* Full ADV support for Syslinux, to boot-once and MENU SAVE
|
|
works.
|
|
* Full support of GPT-partitioned disks, including disks
|
|
and/or parititions larger than 2 TiB (if supported by BIOS.)
|
|
* The GPT handover protocol adjusted to the current T13
|
|
committee draft; see doc/gpt.txt.
|
|
* HDT: code cleanup, small bugfixes
|
|
* The "linux" syslinux installer (syslinux-nomtools) now has a
|
|
command-line syntax closer to the extlinux installer. The
|
|
mtools, dos and win32 installers will get this new syntax
|
|
eventually, but it is not implemented yet.
|
|
* chain.c32: support booting GPT partitions by index, GUID, label.
|
|
* chain.c32: support booting the Syslinux partition with "fs".
|
|
* chain.c32: implement gpt.txt hand-over protocol.
|
|
* chain.c32: support for chainloading Grub stage 2.
|
|
* PXELINUX: TFTP URL syntax (tftp://) supported even when not
|
|
running gPXE/gpxelinux.
|
|
* New ls.c32 module to display the contents of the disk from
|
|
the command line, and pwd.c32 to display the current
|
|
directory.
|
|
* rosh.c32 (read only shell) updated and hopefully usable.
|
|
* PXELINUX: Support "localboot -1", just like the other
|
|
derivatives.
|
|
* gfxboot.com removed in favor of gfxboot.c32.
|
|
* New MENU HELP statement to display fullscreen help text as a
|
|
result of a menu selection.
|
|
* memdiskfind utility that can be used with the phram driver
|
|
in the Linux kernel to mount a memdisk.
|
|
* ifcpu.c32: Adding usage when no parameters are given,
|
|
adding PAE support.
|
|
* ifcpu.c32, ifcpu64.c32: handle more than one argument per
|
|
target.
|
|
* isohybrid: C version which does not require Perl.
|
|
* New command MENU IMMEDIATE to permit hotkeys to activate
|
|
immediately without needing Enter.
|
|
* mdiskchk.com supports a --no-sequential (or -n) option to
|
|
suppress the classic all-drive-probing heuristic. Useful
|
|
on BIOSes who crash/hang when certain drive numbers are
|
|
probed.
|
|
* ElTorito.Sys DOS driver now scans drive numbers upwards
|
|
instead of downwards, in order to avoid a fairly common
|
|
bug on some BIOSes where probing drive 0xFF causes a
|
|
failure.
|
|
* NASM 2.03 or later required to build. 2.07 or later
|
|
recommended.
|
|
|
|
Changes in 3.86:
|
|
* chain.c32: fix chainloading the MBR of a hard disk (broken
|
|
in 3.85).
|
|
* mboot.c32: report the boot loader name in the information
|
|
structure.
|
|
* com32: set argv[0] in a com32 module.
|
|
* core: add a workaround for a bug in Xen HVM older than
|
|
version 3.3: disable halt on those platforms.
|
|
* Fix problems where certain operations in com32 modules would
|
|
cause the core to believe the system was idle.
|
|
* MEMDISK: fix MBR detection when used with a DOSEMU header or
|
|
an offset.
|
|
* MEMDISK: generate the mBFT checksum correctly.
|
|
|
|
Changes in 3.85:
|
|
* gPXELINUX: updated to gPXE 1.0.0. gPXELINUX can now do NBP
|
|
chainloading, and does not require a second DHCP.
|
|
* vesamenu.c32: unbreak the default "grey hole" background.
|
|
* We no longer have a built-in default of "linux auto".
|
|
Instead, if no DEFAULT or UI statement is found, or the
|
|
configuration file is missing entirely, we drop to the boot:
|
|
prompt with an error message (if NOESCAPE is set, we stop
|
|
with a "boot failed" message; this is also the case for
|
|
PXELINUX if the configuration file is not found.)
|
|
* chain.c32: support chainloading Grub4DOS; patch by Gert
|
|
Hulselmans.
|
|
* New tool: sysdump.c32, can be used to produce system
|
|
information for debugging via tftp or ymodem (serial port).
|
|
* "vga=current" on the Linux command line is now supported.
|
|
* chain.c32: support for Windows Recovery Console, via the
|
|
"cmldr=" option.
|
|
* chain.c32: should now support loading NTLDR from different
|
|
type media than loaded from.
|
|
* chain.c32: support chainloading to a FAT/NTFS partition with
|
|
invalid "hidden sectors" via the "sethidden" option.
|
|
* memdisk: fix the mBFT ACPI table.
|
|
* vesamenu.c32: if the image is smaller than the screen, tile
|
|
it across the whole screen.
|
|
* mkdiskimage: -s option for producing a sparse image.
|
|
* vesamenu.c32: support arbitrary resolution setting (beyond
|
|
BIOS support) on some Intel-based video chipsets. This code
|
|
is a modified version of the "915resolution" tool by
|
|
Steve Tomljenovic; your mileage might vary.
|
|
|
|
Changes in 3.84:
|
|
* SYSLINUX: make the DOS installer work for MS-DOS 7.x/8.x
|
|
(Win9x/ME) again.
|
|
* HDT: updated to version 0.3.6 (numerous changes.)
|
|
* mboot.c32: now supports video mode setting if requested by
|
|
the image.
|
|
* MEMDISK: Fix floppy images of PC-DOS.
|
|
* MEMDISK: Add support for emulation of CD-ROM images; patch
|
|
by Shao Miller.
|
|
* MEMDISK: Comply with the Win9x "safe hook" standard,
|
|
allowing a protected-mode driver.
|
|
* MEMDISK: New "mBFT" ACPI table, by analogy with the iSCSI
|
|
iBFT table. This allows detection from a protected-mode
|
|
operating system without EDD support.
|
|
* 32-bit version of the gfxboot loader (gfxboot.c32), so far
|
|
experimental. This will replace gfxboot.com in the future.
|
|
* vesamenu.c32: new MENU RESOLUTION directive to set a screen
|
|
resolution other than 640x480.
|
|
* chain.c32: add support for loading isolinux.bin.
|
|
* chain.c32: make sure to always return to text mode.
|
|
* eltorito.sys: DOS driver for generic CD-ROMs; by Gary Tong
|
|
and Bart Lagerweij.
|
|
|
|
Changes in 3.83:
|
|
* PXELINUX: clear memory before handing over to a chainloaded
|
|
NBP. This may help avoid a bug in Windows RIS.
|
|
* PXELINUX: fix localboot after NBP chainloading on certain
|
|
BIOSes (including ASUS A8N-E, but possibly others.)
|
|
* chain.c32: support chainloaded bootloaders on ISOLINUX.
|
|
* PXELINUX: allow filenames up to 251 characters.
|
|
* MEMDISK: fix problems booting from USB on Thinkpads, and
|
|
possibly other machines or hardware combinations.
|
|
* isohybrid: fix the -id option.
|
|
* HDT: updated to version 0.3.4.
|
|
* MEMDISK: the stack size is now configurable, with the stack=
|
|
option.
|
|
* Simple menu: fix Ctrl-W (word erase) in command-line edit.
|
|
* Simple menu: fix crash on some platforms.
|
|
* Gfxboot: fixes to the configuration file parsing.
|
|
* PXELINUX: add a tool to override specific DHCP options via
|
|
values hardcoded in the pxelinux.0 file. These hardcoded
|
|
values can be either "before DHCP" (defaults if DHCP do not
|
|
provide values), or "after DHCP" (overrides DHCP). The tool
|
|
pxelinux-options can be used to set these options. This
|
|
feature does not apply to gpxelinux.0; when used with gPXE
|
|
this is better handled by modifying the embedded script.
|
|
|
|
Changes in 3.82:
|
|
* isohybrid: fix the -partok logic for loading from a partition.
|
|
* ISOLINUX: deal with systems which return from INT 13h with
|
|
interrupts disabled.
|
|
* Do not invoke the idle handler during large file loads.
|
|
* Simple menu: make ONTIMEOUT work with MENU HIDDEN.
|
|
* PXELINUX: handle TFTP servers which have extra NULs at the
|
|
end of an OACK packet.
|
|
|
|
Changes in 3.81:
|
|
* Shuffler: fix bug in real-mode entry. This affected a
|
|
number of modules, probably in relatively unimportant ways,
|
|
but it completely broke linux.c32.
|
|
* Improved performance.
|
|
* Attempt to halt the processor while idle. This can cause
|
|
bad reponsiveness when using a serial console especially for
|
|
automated input; if that ends up being a problem, use the
|
|
new "NOHALT 1" configuration command.
|
|
* linux.c32 now suppresses all messages if the "quiet" flag is
|
|
specified.
|
|
* isohybrid: add a variety of options, and a help message.
|
|
* ISOLINUX: fix booting in hybrid mode when CBIOS is used.
|
|
This unfortunately means that the isohybrid handoff protocol
|
|
has changed, so the isohybrid utility must version-match
|
|
isolinux.bin.
|
|
* Drop support for ACPI 3 extended memory flags.
|
|
* Menu system: don't set the autocr flag on the serial
|
|
console.
|
|
* altmbr: fix handling of logical partitions.
|
|
* altmbr: cap at 439 bytes so the partition select byte isn't
|
|
part of the file.
|
|
|
|
Changes in 3.80:
|
|
* New shuffler mechanism and API.
|
|
* Rewritten mboot.c32 module.
|
|
* The syslinux_boot_linux() function has been simplified.
|
|
* Don't hang trying to boot a "menu quit" label from the CLI.
|
|
* Fix problem with boot-once "sticking" on some BIOSes.
|
|
* isohybrid: fix problem with images over 2 GB in size.
|
|
* APM poweroff module (poweroff.com) by Sebastian Herbszt.
|
|
* ISOLINUX: fix the handling of large directories. Bug found
|
|
and fixed by Steffen Winterfeldt.
|
|
|
|
Changes in 3.75:
|
|
* PXELINUX: fix the "keeppxe" option, which was broken in
|
|
3.74.
|
|
* MEMDISK: correct the extraction of geometry information from
|
|
the MBR of a hard disk image, again broken in 3.74.
|
|
* extlinux(1) man page from Brian Pellin.
|
|
* Simple menu: MENU SAVE is now controllable on a menu-by-menu
|
|
or entry-by-entry basis.
|
|
* gPXELINUX: fix interrupt-disabling bug.
|
|
* HDT: fix lockup on machines with certain PCI configurations.
|
|
|
|
Changes in 3.74:
|
|
* New UI directive, which allows a more natural way to specify
|
|
a menu system (or not.) With the UI directive specifying
|
|
the menu system, the DEFAULT directive can be used to select
|
|
the default entry inside the menus.
|
|
* kbdmap.c32: new module to load a new keyboard map
|
|
dynamically.
|
|
* isohybrid: workaround bug in some versions of binutils.
|
|
* Fix issue with the placement of the initrd on some machines.
|
|
* ifcpu64: fix handling of less than three arguments.
|
|
* Fix bug in the shuffle library when dealing with a very
|
|
large number of fragments.
|
|
* Documentation fixes by Vicente Jimenez Aguilar.
|
|
* gPXE updated to version 0.9.7.
|
|
* hdt.c32: Hardware Detection Tool, an interactive hardware
|
|
analyzer module by Erwan Velu.
|
|
* MEMDISK: enable automatic determination of the disk geometry
|
|
for a large floppy disk image if (and only if) it is
|
|
formatted with a FAT filesystem.
|
|
* SYSLINUX: fix the handling of .bss files on FAT12/16.
|
|
* Suppress the Loading ... message if "quiet" is specified on
|
|
the kernel command line.
|
|
* Fix the use of "CONSOLE 0" with menu.c32.
|
|
* Allow COM32 modules to be aware of all memory even in the
|
|
presence of a memory hole. The "linux.c32" module can be
|
|
used to load a kernel (or memdisk) plus large initrd on
|
|
such a system.
|
|
* MBR: produce alternate MBR variants which force the drive
|
|
number to hd0 (_f variants), or force the drive number to
|
|
hd0 if the Ctrl key is pressed (_c variants.) Furthermore,
|
|
add an MBR variant (altmbr*.bin) which ignores the active
|
|
flag and instead boots the partition number specified in the
|
|
byte at offset 439 decimal.
|
|
* Add IPAPPEND strings to com32 modules, especially needed for
|
|
linux.c32.
|
|
* New MENU SAVE directive which saves the latest menu
|
|
selection until the next boot. Currently only implemented for
|
|
EXTLINUX.
|
|
* gfxboot.com: *experimental* interface module to Steffen
|
|
Winterfeldt's "gfxboot" graphical front end
|
|
(http://gfxboot.sourceforge.net/). Module by Sebastian Herbszt.
|
|
|
|
Changes in 3.73:
|
|
* Upgrade gPXE to release version 0.9.5.
|
|
* Fix a number of build errors on various platforms.
|
|
* Handle systems with E820 "extended attributes" per ACPI 3.
|
|
Someone "cleverly" decided to change the E820 spec in a
|
|
backwards-incompatible manner!
|
|
* MEMDISK: default to "safeint".
|
|
* Adopt the moniker "The Syslinux Project", standard proper
|
|
noun capitalization, to refer to the project as a whole.
|
|
Thus, reserve the all-caps "SYSLINUX" to refer to the FAT
|
|
loader.
|
|
* mboot.c32: add "-solaris" option to pass DHCP information to
|
|
the Solaris kernel; required for automatic Solaris boot
|
|
without using Solaris' pxeboot program.
|
|
* config.c32: trivial COM32 module to restart Syslinux with
|
|
another configuration file from the command line (equivalent
|
|
to the CONFIG command in the configuratin file.)
|
|
|
|
Changes in 3.72:
|
|
* Include the pxechain.com module from Jeffery Hutzelman at
|
|
Carnegie Mellon University. This allows chaining another
|
|
PXE boot program while changing the DHCP packet passed to
|
|
it.
|
|
* Reorganize the Makefile system.
|
|
* Major PCI core cleanups and other source cleanup.
|
|
* gPXE code updated.
|
|
* Try to avoid memory-snooping attacks on passwords. Note
|
|
that if someone has root on the box, they generally don't
|
|
need to compromise the boot loader...
|
|
* ISOLINUX: fix crash when given a zero-length file.
|
|
* sdi.c32: support gzipped SDI images.
|
|
* ISOLINUX: support generating images which can be either
|
|
a CD-ROM or a hard disk (USB disk, etc.) See
|
|
doc/isolinux.txt for more information.
|
|
* Remote gdb support for COM32 modules; patch from Stefan
|
|
Hajnoczi.
|
|
* Support beeps in F-key help in the simple menu system.
|
|
* Tab display of labels, based on a patch from Sebastian
|
|
Herbszt. Can be disabled with the NOCOMPLETE configuration
|
|
command.
|
|
* "menu default" can now be specified after "menu begin", to
|
|
indicate that a specific submenu should be the default entry.
|
|
|
|
Changes in 3.71:
|
|
* Workaround for a VESA BIOS which tries to make DOS system
|
|
calls(!!)
|
|
* Simple menu: fix navigation around disabled entries
|
|
(or at least try to...)
|
|
* EXTLINUX: proper error message when confused about mount
|
|
point.
|
|
* MEMDISK: be smarter about incompletely disabled floppies in
|
|
the BIOS and about being the only floppy.
|
|
* Optionally allow initrd to be specified on a separate line
|
|
rather than as part of the "append" line. This is not
|
|
recommended, but apparently makes life easier for some
|
|
tools.
|
|
* SYSLINUX: if no config file is present, set the current
|
|
directory to the root directory (Sebastian Herbszt).
|
|
* chain.c32: option "hide" to support hiding and unhiding of
|
|
primary partitions on the boot drive with DOS, Win, or OS/2
|
|
partition types (01, 04, 06, 07, 0b, 0c, 0e).
|
|
* Unbreak the KBDMAP command (broken in 3.70).
|
|
* EXTLINUX: fix the handling of the ADV when using CBIOS.
|
|
* ifcpu64.c32: simple COM32 module to select a 32- or 64-bit
|
|
kernel (and optionally 32-bit kernels with or without PAE.)
|
|
Eventually we want a scripting language for this
|
|
kind of stuff; a Lua module is under development.
|
|
* Fix parsing of the SERIAL command without a baud rate
|
|
specified.
|
|
* chain.c32: error out when try to boot an unbootable
|
|
partition.
|
|
* SYSLINUX: when building the Win32 installer, search for
|
|
MinGW under a large number of possible names.
|
|
|
|
Changes in 3.70:
|
|
* PXELINUX: Support enhanced capabilities when running on top
|
|
of gPXE (http://www.etherboot.org/). In particular, support
|
|
URL-style syntax for filenames, and any protocol that gPXE
|
|
supports (except, currently, iSCSI and AoE.) This feature
|
|
is currently highly experimental.
|
|
* Substantial infrastructure changes to support files whose
|
|
length aren't known at open time (typically network
|
|
connections.) Please note that the semantics of some of the
|
|
comboot APIs have changed slightly; please see doc/comboot.txt.
|
|
* PXELINUX: We no longer require a TFTP server which supports
|
|
the tsize option for all transfers.
|
|
* PXELINUX: Integrate with the gPXE source base; unified image
|
|
now included as "gpxelinux.0".
|
|
* The source tree has been restructured; files that were
|
|
previously in the root have moved into the core, dos, gpxe,
|
|
and utils directories.
|
|
* "make install", "make netinstall", and "make extbootinstall"
|
|
have been updated massively. "make install-all" now installs
|
|
all three.
|
|
* Change default dir for auxiliary files from
|
|
/usr/lib/syslinux to /usr/share/syslinux.
|
|
* SYSLINUX: VFAT long filename support.
|
|
* MEMDISK: Any image less than 4096K (4 MB) is treated as a
|
|
floppy disk. The geometry-guessing code will recognize all
|
|
common extended formats, but it is still possible some very
|
|
exotic formats need geometry specification. Large floppies
|
|
and very small harddisks still need explicit specification.
|
|
* chain.c32: option "swap" to support swapping of BIOS drive
|
|
numbers. This is necessary to boot certain operating systems
|
|
(DOS, Windows) from a secondary drive.
|
|
* chain.c32: option "file=" to support loading a boot file from
|
|
the SYSLINUX filesystem instead of loading the boot sector
|
|
from the drive.
|
|
* chain.c32: option "seg=" to control the load location.
|
|
* chain.c32: option "ntldr=" as a shorthand for "seg=0x2000
|
|
file="; use this to load one of WinNT's loaders:
|
|
|
|
chain.c32 hd0 1 ntldr=/MiniNT/setupldr.bin
|
|
|
|
Note that the file needs to be in the SYSLINUX filesystem.
|
|
* chain.32: options "freedos=" and "msdos="/"pcdos=" as
|
|
shorthands for "seg=0x60 file=" and "seg=0x70 file="
|
|
respectively; use this to load FreeDOS's kernel.sys, MS-DOS's
|
|
io.sys or PC-DOS's ibmbio.sys.
|
|
* Change to the A20 algorithm which *MIGHT* help systems that
|
|
have systems which freeze when Syslinux is used with USB
|
|
keyboards. Note that this has been hard do verify, so I
|
|
would greatly appreciate feedback on it.
|
|
* Complex menu system: unbreak menus which has unnamed
|
|
submenus, like complex.c.
|
|
* Fix newline on the serial port for some com32 modules.
|
|
* chain.c32: support "boot" as the drive specification,
|
|
indicating the drive from which it was booted
|
|
(for syslinux/extlinux).
|
|
* SYSLINUX/EXTLINUX: support "localboot" with the same feature
|
|
set as ISOLINUX.
|
|
* Add an experimental MBR for GPT partition tables.
|
|
* Use $(CC) when determining compile flags.
|
|
* chain.c32: fix booting from logical partitions (Sergey
|
|
Vlasov.)
|
|
|
|
Changes in 3.63:
|
|
* Fix errors in the PCI and DMI detection modules (Erwan Velu,
|
|
Sebastian Herbszt).
|
|
* Fix host dependencies and other issues in the build system.
|
|
* PXELINUX: Allow class E addresses as unicast.
|
|
* sdi.c32: module to load Microsoft System Deployment Images.
|
|
For additional information, please see:
|
|
http://msdn2.microsoft.com/en-us/library/ms838543.aspx
|
|
* EXTLINUX: Correct reading directories with deleted entries.
|
|
* Shuffle library: correct the handling of certain geometries
|
|
(an upward move with source material blocking the move); as
|
|
required by sdi.c32 but theoretically possible for other
|
|
formats as well.
|
|
* Add "make netinstall" to install /tftpboot.
|
|
* Fix some documentation files that didn't get moved/renamed.
|
|
|
|
Changes in 3.62:
|
|
* Clean up garbage after "aborted." message.
|
|
* Clean up memdump.com filenames.
|
|
* Support SHA256 and SHA512 encrypted passwords.
|
|
* The shuffle library now can generate chained descriptors,
|
|
thus allowing pretty much arbitrarily complex memory maps.
|
|
* Handle command lines up to 2047 characters, the current
|
|
Linux kernel limit.
|
|
* vesamenu: support systems without linear framebuffer support
|
|
(sigh, what is this, 1993?) and 15-bit RGB modes.
|
|
* Move the label storage (for the command-line interface) to
|
|
high memory, removing the size limit and freeing up 64K of
|
|
low memory.
|
|
* Get rid of 4096-entry limit in the simple menu system.
|
|
* New hierarchial submenu support: see MENU BEGIN, MENU END,
|
|
MENU GOTO in doc/menu.txt.
|
|
* MENU QUIT allows creating a menu entry for returning to the
|
|
command line.
|
|
* ISOLINUX: Work around bug in certain Adaptec BIOSes,
|
|
patch by Bruce Robson.
|
|
* pngtopnm dependency removed from samples/ directory.
|
|
* Text documentation files (in doc/) renamed *.doc -> *.txt.
|
|
|
|
Changes in 3.61:
|
|
* EXTLINUX: fix crash when accessing an empty file.
|
|
* elf.c32: If a PHDR segment is present, load it.
|
|
* Fix SHA-1 and MD5 passwords.
|
|
* ISOLINUX: fix booting when mastered without
|
|
mkisofs -boot-info-table (broken since 3.50, sigh...)
|
|
* Handle BIOSes which emit multiple contiguous valid
|
|
memory regions in the e820 map.
|
|
|
|
Changes in 3.60:
|
|
* Support for "auxilliary data vector", a small amount of
|
|
writable storage. Currently only supported for EXTLINUX,
|
|
but the infrastructure is there for the other derivatives,
|
|
assuming a suitable storage location can be found.
|
|
* EXTLINUX: boot-once support (--once, --clear-once, and
|
|
--reset-adv).
|
|
* A command is now required to the EXTLINUX installer, i.e. at
|
|
least one of --install, --update, --once, --clear-once, or
|
|
--reset-adv.
|
|
|
|
Changes in 3.55:
|
|
* PXELINUX: as per RFC 5071, PXELINUX no longer requires the
|
|
use of the magic cookie option (208) for unencapsulated
|
|
options. Currently it does not require it for
|
|
vendor-encapsulated options (vendor-option-space) either,
|
|
but that MAY be reverted in the future if it causes
|
|
problems.
|
|
* Documentation text files moved to a common "doc" directory;
|
|
man pages from the Debian project added to the "man"
|
|
directory.
|
|
* Correct bug with self-overlapping memory areas when using
|
|
the shuffle interface.
|
|
|
|
Changes in 3.54:
|
|
* Add "menu separator", "menu indent", "menu disabled"
|
|
(see README.menu).
|
|
* vesamenu: fix handing of VESA modes with noncontiguous
|
|
memory buffers. In particular, Qemu/KVM sets up such a mode
|
|
when Cirrus Logic emulation is enabled (which is the
|
|
default.)
|
|
* Support for calling real mode functions using far calls,
|
|
with argument on the stack. This was implemented to support
|
|
the BIOS BBS specification, but subsequent experiments show
|
|
that the at least one of the most common BIOS cores, Award,
|
|
passes the presence check but doesn't actually implement the
|
|
functionality.
|
|
|
|
Changes in 3.53:
|
|
* Fix bugs related to the $PnP BIOS functionality on some
|
|
platforms.
|
|
* PXELINUX: Fix the "naked" version of :: (suppress prefix.)
|
|
* elf.c32: better error messages.
|
|
* Faster operation under Intel VT virtualization.
|
|
* PXELINUX: Fix DHCP bootfile option.
|
|
* mkdiskimage: Support more than 1024 cylinders.
|
|
* (Hopefully) fix installer on non-x86 platforms.
|
|
* Fix shuffle_and_boot_rm, used by linux.c32.
|
|
* Fix shuffle_and_boot_pm on 386/486.
|
|
* ISOLINUX (at least): fix bss memory overwrite hang.
|
|
* MBR: Fix booting from logical partitions.
|
|
* Code cleanups.
|
|
|
|
Changes in 3.52:
|
|
* Handle capitalized F-key commands in the menu system.
|
|
* Fix padding error when loading multiple ramdisks.
|
|
* Workaround for VMware crashing when trying to print a
|
|
message during early kernel boot (does not seem to work,
|
|
consider deleting.)
|
|
* chain.c32: add the ability to search for a specific MBR
|
|
signature at runtime.
|
|
* Fall back to the server identity option if the siaddr field
|
|
in the DHCP header isn't set. This seems to match the
|
|
behaviour of most PXE stacks.
|
|
* mkdiskimage: give the generated disk image an MBR signature.
|
|
* MEMDISK: Fix failures on some BIOSes.
|
|
* Simple menu system: new "MENU HIDDEN" option to not display
|
|
the menu unless the user presses a key.
|
|
* Simple menu system: support MD5-encrypted passwords (modern
|
|
Unix standard style, with "$1$" prefixes.)
|
|
* pcitest.c32: now functions as a full "lspci". Thanks to
|
|
Erwan Velu for this work.
|

* MEMDISK: Make EDD actually work.
|
|
* ISOLINUX: Fix for certain broken CD-ROM BIOSes which
|
|
randomly corrupted register FS.
|
|
* Simple menu system: fix memory overwrite bug that caused
|
|
some systems to lock up or behave weirdly.
|
|
* Fix building on 64-bit systems without a 32-bit libc installed.
|
|
|
|
Changes in 3.51:
|
|
* EXTLINUX: Fix failure to find the configuration file.
|
|
|
|
Changes in 3.50:
|
|
* New keywords allow the type of file to be specified in the
|
|
configuration file.
|
|
* It is now supported to load a different configuration file
|
|
with the CONFIG keyword.
|
|
* Fix API call 0x0019 (Read Disk.)
|
|
* MENU AUTOBOOT, MENU TABMSG, MENU PASSPROMPT allows
|
|
internationalization of menu messages.
|
|
* A new feature, TEXT HELP, allows the administrator to set
|
|
a multi-line help message for individual selections.
|
|
* Fix API call 0x0012 (Cleanup, shuffle and boot.)
|
|
* New API call "Cleanup, shuffle and boot to flat protected mode"
|
|
* New API call "Cleanup, shuffle and boot to real mode",
|
|
similar to API call 0x0012 but allows arbitrary register setting.
|
|
* Introduce a library interface for loading arbitrary binary
|
|
formats with relatively easily understood code. See
|
|
the elf.c32 module for an example on how to use it.
|
|
* New module "elf.c32", to load a protected-mode ELF kernel.
|
|
* MBR (old and new): Fix bug in CHS mode when LBA >
|
|
65535*sectors.
|
|
* vesamenu: fix decoding of palettized PNG images.
|
|
* Update the Linux kernel boot protocol.
|
|
* PXELINUX: Press Ctrl-N at the boot prompt to read out the
|
|
network info.
|
|
* Instead of the (non-existent) MAC, use the client identifier
|
|
for networks like Infiniband and Firewire/1394.
|
|
* Add a new INCLUDE command to the core syslinux parser.
|
|
* Allow binding help text to F11 and F12.
|
|
* F-key help now available in the simple menu system.
|
|
* Disabled the polling for ARP during idle. It is simply too
|
|
slow on some (broken!) PXE stacks.
|
|
* PXELINUX: also try to fetch the config file based on UUID.
|
|
* SYSLINUX/EXTLINUX: New RAID mode (-r) which calls the BIOS
|
|
to load the next device (typically the next drive) on boot
|
|
failure.
|
|
|
|
Changes in 3.36:
|
|
* MEMDISK: Disable EDD by default on floppy disks. EDD can be
|
|
enabled with the "edd" option and disabled with "noedd".
|
|
This (hopefully) should make Ghost work again.
|
|
* SYSLINUX: "unix" installer now uses Linux ioctls instead of
|
|
using libfat.
|
|
* New MBR which can boot from logical partitions.
|
|
* SYSLINUX: Fix bug in detecting special extensions which was
|
|
introduced in 3.35 :(
|
|
* PXELINUX: Unbreak chainbooting FreeBSD (and possibly others.)
|
|
|
|
Changes in 3.35:
|
|
* MEMDISK: New "safeint" mode.
|
|
* MEMDISK: Be more compliant with the PnP BIOS spec.
|
|
* MEMDISK: Turn on EDD support by default.
|
|
* MEMDISK: Try to work on some machines on which it would not
|
|
work when there was no floppy drive in the system.
|
|
* Simple menu system: fix serial console support (broken in
|
|
3.30).
|
|
* SYSLINUX: Support subdirectories. Like ISOLINUX, the
|
|
"current directory" is the directory in which syslinux.cfg
|
|
is found; this is searched for in the sequence
|
|
/boot/syslinux, /syslinux, /. As a side benefit, label names
|
|
like "linux-2.6.18" and "linux-2.6.19" are now supported.
|
|
|
|
To install ldlinux.sys in a subdirectory, pass the -d
|
|
directory option to the SYSLINUX installer.
|
|
|
|
This work was sponsored by slax.org (thanks, Tomas!)
|
|
* New API call: read disk.
|
|
* Invoke ONERROR on initrd load failure.
|
|
|
|
Changes in 3.31:
|
|
* The simple menu system (menu.c32 and vesamenu.c32) now
|
|
support loading more than one configuration file at a time,
|
|
using MENU INCLUDE or by specifying multiple filenames.
|
|
* The MENU COLOR statement can now control the shadowing mode.
|
|
|
|
Changes in 3.30:
|
|
* libcom32 extended to support graphics mode and graphical console.
|
|
* vesamenu.c32, new graphical version of the Simple
|
|
Menu System, see README.menu.
|
|
* New com32 modules by Erwan Velu do selection based on CPUID
|
|
or PCI devices present.
|
|
* RPM spec: add syslinux-tftpboot module; move syslinux by
|
|
default to the /usr/share/syslinux directory.
|
|
* RPM spec: extlinux is now a separate package.
|
|
|
|
Changes in 3.20:
|
|
* EXTLINUX: New options --install (-i) and --update (-U), to
|
|
make it clear if a boot loader should be installed or
|
|
updated. For now, defaults to --install for compatibility;
|
|
a future version will require one of these options.
|
|
* New library functions to load and place files in memory.
|
|
* mboot.c32 bug fixes.
|
|
* Remove 8 MB kernel size restriction.
|
|
* Add "klibc" target for building unix/syslinux and
|
|
extlinux/extlinux with klcc (klibc-1.4.27 or later.)
|
|
* PXELINUX: Fail (and eventually reboot) if no configuration
|
|
file was found.
|
|
* COM32 module by Erwan Velu to make decisions based on DMI
|
|
info.
|
|
* Fix issue where going back and forth between menus a lot
|
|
would cause a hang.
|
|
* ISOLINUX: Fix bug which made "cd boot sectors" not work.
|
|
|
|
Changes in 3.11:
|
|
* MEMDISK: Fix bug by which accessing the real floppy disk
|
|
as B: in MS-DOS was broken.
|
|
* Simple menu system: allow tweaking of the screen layout.
|
|
* Simple menu system: better command-line editing, correctly
|
|
handle command lines above 256 characters.
|
|
* PXELINUX: revert memory allocation change that caused
|
|
problems on some network cards.
|
|
* MEMDISK: Try work around a bug on some BIOSes when no
|
|
physical floppy disk is present in the system.
|
|
* Enable the 16550A FIFOs, if present, when doing serial
|
|
console.
|
|
* New "totaltimeout" command establishes a timeout without
|
|
regard for any user input.
|
|
* Simple menu system: timeout behaviour now more in line with
|
|
user expectations.
|
|
* Simple menu system: "ontimeout" should now work correctly.
|
|
|
|
Changes in 3.10:
|
|
* gcc 4.0.1 compilation fixes.
|
|
* Add support for querying the PCI BIOS in libcom32
|
|
(used by ethersel et al.)
|
|
* Fix PCI handing (ethersel etc) on several old chipsets (and
|
|
VMWare.)
|
|
* Try to deal with systems with broken EBIOS.
|
|
* New API call to do "localboot".
|
|
* New API call to query features.
|
|
* New API call to run kernel image, a lower-level call than
|
|
"run command". See comboot.doc.
|
|
* Fix for bug in EBIOS code discovered by Arwin Vosselman.
|
|
* NOESCAPE security fix.
|
|
* Comments are now recognized even without a space following #.
|
|
* Fix incorrect handling of mixes of entries with and without
|
|
MENU PASSWD.
|
|
* The idle API call now harmlessly returns failure if it is a
|
|
no-op. That way the caller can decide whether or not to
|
|
bother invoking it again.
|
|
* Temporarily disable the idle API call on PXELINUX, due to
|
|
some platforms on which the idle API call seems to hang; this
|
|
problem has not yet been debugged.
|
|
* MEMDISK: the handling of DOSEMU-headered images was broken;
|
|
fix it.
|
|
* EXTLINUX: symlinks are now supported.
|
|
* Simple menu system: N and P now work correctly as hotkeys.
|
|
* MEMDISK: more BIOS bug workarounds.
|
|
|
|
Changes in 3.09:
|
|
* gcc4 compilation fix.
|
|
* <BEL> (Ctrl-G) in message files now causes a beep.
|
|
* Reduce the command line to 511 characters; 1023 caused
|
|
memory overflows.
|
|
|
|
Changes in 3.08:
|
|
* SYSLINUX: Fix performance regression (-s mode always
|
|
enabled.)
|
|
* Add API function for idle loop.
|
|
* libutil: Add do_idle() function for idle loop, make
|
|
get_key() use it.
|
|
* libutil: Add SHA-1 and base64 functions.
|
|
* Simple menu system: add password support.
|
|
* EXTLINUX: Sparse files now handled correctly.
|
|
* EXTLINUX: Large directories now handled correctly.
|
|
* ALL: At the prompt, Ctrl-X now forces text mode.
|
|
* Fix configuration file parsing error, that could cause
|
|
hangs.
|
|
* Rewritten advanced menuing system from Murali Ganapathy.
|
|
* MEMDISK: New "bigraw" mode to work around certain broken
|
|
BIOS flash programs.
|
|
* COM32 module to boot Multiboot systems, including Xen. See
|
|
com32/modules/mboot.doc.
|
|
* Max command line changed to 1023 characters. Note that the
|
|
kernel proper still can only handle 255 characters without
|
|
patching, and COM16 binaries can only handle 125 characters.
|
|
|
|
Changes in 3.07:
|
|
* Fix chainloading (chain.c32).
|
|
* Fix zlib build problem.
|
|
* Use a private copy of <linux/ext2_fs.h>.
|
|
|
|
Changes in 3.06:
|
|
* Fix typo that caused the ramdisk to load in the wrong place.
|
|
|
|
Changes in 3.05:
|
|
* New API function "shuffle and boot"; allows COM32 modules to
|
|
load or construct (almost) arbitrarily complex objects,
|
|
e.g. a kernel and its initrd/initramfs in pieces, and have
|
|
the API core reorganize memory for booting. (A library API
|
|
for this function will be introduced in a later version.)
|
|
* The initrd= option now supports multiple filenames separated
|
|
by commas. This is mostly useful for initramfs, which can
|
|
be composed of multiple separate cpio or cpio.gz archives.
|
|
(Note: all files except the last one are zero-padded to a 4K
|
|
page boundary. This should not affect initramfs.)
|
|
* EXTLINUX: Fix API function 000Ah (get derivative-specific
|
|
info).
|
|
* libcom32/ethersel: Support PCI Config Mechanism #2 on
|
|
machines still infested with that hideous old hack.
|
|
* SYSLINUX: Fix directory-parsing bug.
|
|
|
|
Changes in 3.02:
|
|
* SYSLINUX: The "unix" installer now sets the MS-DOS
|
|
attributes (hidden, system, readonly.)
|
|
* COM32 library: build the .lnx (test modules for running
|
|
under Linux) as architecture native modules, in case
|
|
i386 devel libraries aren't installed.
|
|
* EXTLINUX: Hack for systems which don't have BLKGETSIZE64
|
|
defined in the standard header files.
|
|
* Simple menu system: minor aestetic improvements, and try to
|
|
work better over a serial console (speed, and readability on
|
|
monochrome terminal emulators.)
|
|
* New CONSOLE directive to control output on the video console
|
|
(useful for dealing with some broken serial-forwarding
|
|
BIOSes.)
|
|
* New com32 module "ethersel" for searching for an Ethernet
|
|
card and selecting the proper version of Etherboot.
|
|
* EXTLINUX: Allow the user to override the detected geometry.
|
|
Add help.
|
|
|
|
Changes in 3.01:
|
|
* EXTLINUX, SYSLINUX: Fix compile errors on some systems.
|
|
* EXTLINUX: Default to zipdrive geometry (64 heads, 32
|
|
sectors) if no other geometry can be detected.
|
|
|
|
Changes in 3.00:
|
|
* SYSLINUX: Support FAT32 and EDD. As an unfortunate
|
|
consequence, LDLINUX.SYS is no longer an ordinary file; it
|
|
is block-mapped at install time, which means it can only be
|
|
written using the syslinux installers.
|
|
* SYSLINUX: Reorganize the source code for the installers;
|
|
each one of the installers (dos, win32, unix, mtools) is now
|
|
built in its own subdirectory. In particular, "mtools" is
|
|
the unprivileged installer which uses mtools; "unix" is the
|
|
privileged installer which uses system calls.
|
|
* SYSLINUX: Completely rewritten DOS installer in C.
|
|
* ALL: "label" statement information is now stored in a
|
|
compressed format, which means that a lot more labels are
|
|
permitted (500-1000 in a typical configuration, but depends
|
|
on the complexity.)
|
|
* EXTLINUX: New derivative, which boots from an ext2/ext3
|
|
filesystem.
|
|
* SYSLINUX: The DOS and Win32 installers can now optionally
|
|
write the boot sector to a file instead of the real boot
|
|
sector. This is not supported in the Linux installers,
|
|
however.
|
|
* ALL: New NOESCAPE command, disables the "hold down the Shift
|
|
key to display the prompt" behaviour.
|
|
* New simple menu system, as an alternative to the advanced
|
|
menu system already present. See README.menu for details.
|
|
* PXELINUX: Filenames can now be prefixed with an IP address
|
|
or DNS name plus :: (e.g. 192.0.2.1::filename or
|
|
server.domain.com::filename), which downloads a file from an
|
|
alternate TFTP server, or just a :: (e.g. ::filename), which
|
|
suppresses the common pathname prefix. See pxelinux.doc.
|
|
* SYSLINUX: Add an -m option to the DOS and Win32 installers
|
|
to write an MBR and -a to mark the partition SYSLINUX is
|
|
being installed on active.
|
|
* MEMDISK: Give a way to query the boot loader type while
|
|
running MEMDISK; see memdisk/memdisk.doc and
|
|
sample/mdiskchk.c.
|
|
* mkdiskimage: substantially improved mkdiskimage which, among
|
|
other things, can now be used to initialize USB keys as
|
|
zipdrives; see README.usbkey for more information.
|
|
|
|
Changes in 2.13:
|
|
* MEMDISK: Fix command-line parsing "brown paper bag" class
|
|
bug.
|
|
* MEMDISK: Add "raw" mode to support the DOS boot disk from
|
|
WinME/XP, which seems to deliberately crash the system
|
|
when someone uses the "INT 15h mover" highmem API.
|
|
* Make "make install" do something sane for the com32
|
|
development environment.
|
|
* In the spec file, create a separate -devel RPM for the com32
|
|
development environment.
|
|
|
|
Changes in 2.12:
|
|
* Simple C library, based on klibc, for writing COM32
|
|
programs.
|
|
* Fix the handling of file length in loading of COM32
|
|
programs.
|
|
* MEMDISK: Work around a linker bug by rearranging the code to
|
|
not use the linker for the 16-bit code.
|
|
* SYSLINUX: If we're building on a machine without a Win32
|
|
(mingw) compiler, just skip building syslinux.exe.
|
|
* ISOLINUX: Support non-mkisofs mastering programs, at least
|
|
as long as the image is single-session. For best results,
|
|
ISOLINUX should be the only boot loader installed.
|
|
* MEMDISK: Allow the user to specify that the simulated disk
|
|
should be write-protected.
|
|
|
|
Changes in 2.11:
|
|
* ALL: Add an API call to get the configuration file name.
|
|
* SYSLINUX: Fix bug in 2.10 that prevented it from working
|
|
correctly for a lot of people.
|
|
* SYSLINUX: In the installer, make mtools a bit less fussy.
|
|
* Make the menu system compile with newer gcc's.
|
|
|
|
Changes in 2.10:
|
|
* MEMDISK: Handle images compressed with zip as well as with
|
|
gzip. Some Windows-based image tools apparently generate
|
|
these kinds of images by default. Patch by Patrick
|
|
LoPresti.
|
|
* Major menu improvement from Murali Ganapathy.
|
|
* ISOLINUX: Wonderfully sick and brilliant workaround for
|
|
severe bugs in certain Award BIOSes; from Knut Petersen.
|
|
* SYSLINUX: Fix for the nomtools installed, from Frederic
|
|
Pasteleurs.
|
|
* PXELINUX: Fix handling of IP numbers in the ranges
|
|
100-109 and 200-209.
|
|
* ALL: New option "allowoptions" (defaults to 1), which
|
|
controls if options are allowed on the command line or not.
|
|
* SYSLINUX: Support building under klibc (see the klibc
|
|
distribution for details.)
|
|
|
|
Changes in 2.09:
|
|
* SYSLINUX: Remove residual setuid crap from
|
|
syslinux-nomtools.
|
|
* Handle video pages correctly when using the API functions.
|
|
* Handle compiling on an x86-64 platform correctly.
|
|
* Menu system from Murali Krishnan Ganapathy; see the menu
|
|
directory for information.
|
|
* COMBOOT: Allow COMBOOT programs to change screen text mode.
|
|
* COMBOOT: Correct the documentation of how to detect
|
|
SYSLINUX from COMBOOT!!!!
|
|
* COMBOOT: Fix "get key without echo" API function.
|
|
* SYSLINUX: Fix bug that affected the API open function.
|
|
* ALL: Improve the E820 memory parser, to work around some
|
|
buggy BIOSes.
|
|
|
|
Changes in 2.08:
|
|
* Add new configuration command "ontimeout" to allow timeout
|
|
to have a different action than just pressing Enter.
|
|
* Add new configuration command "onerror" to allow a custom
|
|
command to be executed in case the kernel image is not found.
|
|
* Fix bugs in the COMBOOT/COM32 command-line parsing. APPEND
|
|
now works with COMBOOT/COM32 images.
|
|
* PXELINUX: Poll for ARP requests while sitting at the
|
|
prompt. This makes some boot servers a lot less unhappy.
|
|
* PXELINUX: Actually free sockets when we get a failure
|
|
(including file not found.) This bug would cause us to run
|
|
out of sockets and thus "go deaf" after a while.
|
|
* MEMDISK: Add an API to query for the existence of MEMDISK.
|
|
* SYSLINUX: Fix loading boot sectors (.bs/.bss) from floppy
|
|
disk.
|
|
* .c32 is now one of the extensions searched for
|
|
automatically.
|
|
* PXELINUX: RFBG.exe seems to randomly overwrite memory
|
|
location 0x5700. Thus, don't use it!
|
|
* PXELINUX: Change pathname length max from 63 to 127; change
|
|
max vkernels from 128 to 64.
|
|
* Support Ctrl-U -> kill entire command line input.
|
|
* The "samples" directory contains a (barely at all tested)
|
|
chain loading example, chain.c32, which may be used to
|
|
chainload local floppy disks and hard disks. Use with
|
|
"chain fdN" or "chain hdN [partition]"; N = 0 for the first
|
|
drive of each type.
|
|
|
|
Changes in 2.07:
|
|
* MEMDISK: Workaround for BIOSes which go into a snit when
|
|
they get a RESET command for the floppy system when there is
|
|
no floppy in the system.
|
|
* PXELINUX: Add "ipappend 2", which passes the hardware
|
|
address of the boot interface to the kernel as a
|
|
command-line option.
|
|
* mkdiskimage: fix the generation of the end limit.
|
|
* PXELINUX: Fix multiple bugs in chainloading of other NBPs.
|
|
* MEMDISK: Fix bug that would occationally cause "ran out of
|
|
input data" when using compressed disk images.
|
|
* SYSLINUX: Updates for the win32 installer (from Lars Munch.)
|
|
* PXELINUX: PXELINUX-specific options are now recognized both
|
|
in a vendor-option-space (a.k.a. type 43 encapsulated) as
|
|
well as in a site-option-space (unencapsulated.)
|
|
* COM32: Don't crash when DS != 0.
|
|
* COMBOOT/COM32: Make file reading work correctly. Thanks to
|
|
Phung Chi Kien for submitting a test program.
|
|
|
|
Changes in 2.06:
|
|
* ALL: Fix problem that would occationally cause a
|
|
boot failure, depending on the length of the kernel.
|
|
* ISOLINUX: Fix problem that would occationally cause a
|
|
boot failure, depending on the length of directories.
|
|
* SYSLINUX: Win32 installer now flushes buffers.
|
|
* ppmtolss16: Be fully compliant with the PNM spec;
|
|
actually process comments in the header and odd
|
|
alignments of the various parameters, as well as
|
|
"plain" (not raw) files and PBM and PGM files.
|
|
* PXELINUX: Lower the default MTU to 1472 in order to deal
|
|
with systems with slightly nonstandard MTUs, and PXE
|
|
stacks which don't defragment correctly. Unfortunately this
|
|
is very hard to test dynamically.
|
|
|
|
Changes in 2.05:
|
|
* PXELINUX: Add a default query based on the hardware address
|
|
of the boot device. This is in lower case hexadecimal form
|
|
separated by dashes and including the hardware type, for
|
|
example, the Ethernet (type 1) address 88:99:AA:BB:CC:DD
|
|
would query the file pxelinux.cfg/01-88-99-aa-bb-cc-dd.
|
|
* PXELINUX: Fix bug involving non-IP-based config file names.
|
|
* SYSLINUX: New installer for WinNT-based systems, from Lars
|
|
Munch.
|
|
* MEMDISK: Fix handling of memory region overlap when
|
|
decompressing. Thanks to Mikhail Kupchik for identifying
|
|
the problem.
|
|
|
|
Changes in 2.04:
|
|
* ALL: Reclaim even more low memory by observing that
|
|
comboot_seg == real_mode_seg is perfectly fine, and by the
|
|
fact that the 1000h segment managed to get unused in all
|
|
derivatives...
|
|
* PXELINUX: Attempt to negotiate full Ethernet-sized blocks
|
|
(1468 bytes) using the blksize option.
|
|
* SYSLINUX: Resurrect the old no-mtools version of the
|
|
installer, although as a root-only tool. Some distributors
|
|
have indicated that they need a small standalone installer.
|
|
* MEMDISK: Fix a memory offset computation error when
|
|
installing compressed disks which generally would cause
|
|
1 MB of memory to be wasted.
|
|
* MEMDISK: Fix installing the E820 memory map. Calling
|
|
INT 15h AX=0E820h with MEMDISK 2.03 loaded would give a
|
|
completely corrupt memory map.
|
|
* SYSLINUX: Make libsyslinux a dynamic library, so that it can
|
|
be updated separately from client programs. The whole idea,
|
|
after all, is to enable alternate programs to become
|
|
syslinux installers.
|
|
* Include an rpm spec file in the distribution, so rpmbuild
|
|
-ta works.
|
|
|
|
Changes in 2.03:
|
|
* Actually support comment lines in the configuration file.
|
|
* PXELINUX: Try to resolve some problems with stack switches.
|
|
* PXELINUX: Handle PXE stacks with broken routing.
|
|
With these workarounds, the remote install PXE boot floppy
|
|
(rbfg.exe) from Argon Technologies should work correctly.
|
|
* Fix problems with Perl scripts in UTF-8 locales.
|
|
* You probably need NASM 0.98.34 or later to compile this
|
|
version. 0.98.36 is recommended.
|
|
* MEMDISK: Now supports gzip compressed images.
|
|
|
|
Changes in 2.02:
|
|
* SYSLINUX: Security flaws have been found in the SYSLINUX
|
|
installer when running setuid root. Rewrite the SYSLINUX
|
|
installer so it uses mtools instead. It therefore now
|
|
requires mtools (specifically mcopy and mattrib) to exist on
|
|
your system, but it will not require root privileges and
|
|
SHOULD NOT be setuid.
|
|
|
|
Changes in 2.01:
|
|
* MEMDISK: Fix memory sizing bug when the ramdisk crosses the
|
|
16 MB boundary.
|
|
* MEMDISK: Add a "pause" option to stop immediately before
|
|
booting, to read off the messages.
|
|
* MEMDISK: Support disk images with DOSEMU headers.
|
|
* Update the mkdiskimage script to handle newer mtools
|
|
versions, and be able to generate disk images with DOSEMU
|
|
headers (controlled by the -d option).
|
|
* Fix the COM32 sample program.
|
|
* PXELINUX, ISOLINUX: Fix some COMBOOT API calls.
|
|
* PXELINUX: Doc fix.
|
|
* Build SYSLINUX into a small library for encapsulation into
|
|
other programs (however, please keep in mind this is a GPL'd
|
|
library.)
|
|
* SYSLINUX: Make installer work with "owner" in /etc/fstab.
|
|
* SYSLINUX: Fix issue with working on nonpartitioned hard disk
|
|
devices. THIS CONFIGURATION IS NOT RECOMMENDED.
|
|
|
|
Changes in 2.00:
|
|
* ALL: Add support for "COM32" (32-bit COMBOOT) images.
|
|
* ALL: Add an API for COMBOOT/COM32 images. See comboot.doc
|
|
for details. There is a C development environment for
|
|
COM32 being created; it should be ready at some point in
|
|
the future.
|
|
* Fix mbr.asm so that it actually works.
|
|
* SYSLINUX: The syslinux installer *SHOULD* now be safe to
|
|
run setuid root.
|
|
* PXELINUX: Fix bug where PXELINUX would override random
|
|
chunks of the UNDI code segment! Thanks to Kevin Tran for
|
|
finding this bug.
|
|
* ISOLINUX: Fix a bug related to slashes in pathnames.
|
|
* ISOLINUX: Fix a bug in handling initrds over 128 MB.
|
|
* ALL: Make the <Ctrl-V> key print out the version; this is
|
|
to help debugging.
|
|
* Add a small script, mkdiskimage, to create a DOS-formatted
|
|
hard disk image using mtools. This may be useful in
|
|
conjunction with MEMDISK.
|
|
* ISOLINUX: Search for a /boot/isolinux directory as well as
|
|
/isolinux.
|
|
* ALL: Fix a bug related to very long configuration files.
|
|
* PXELINUX: Work around a NASM bug which would result in no
|
|
delay before reset if an error occurs.
|
|
|
|
Changes in 1.76:
|
|
* ISOLINUX: Remove code no longer used which caused hangs on
|
|
some Toshiba laptops.
|
|
|
|
Changes in 1.75:
|
|
* ALL: NASM 0.98.32 or later is now required to build
|
|
SYSLINUX from sources.
|
|
* SYSLINUX: put back in the workaround for the BIOS floppy
|
|
table. This seems to be a requirement for "extended" floppy
|
|
formats to work correctly.
|
|
* SYSLINUX: No longer warn if one is trying to boot on a 286
|
|
or older. The above BIOS workaround no longer fits if the
|
|
requirement to use only 8086-compatible code in the early
|
|
boot is maintained. It made sense in 1994, but in 2002 a
|
|
286 or older is a museum object.
|
|
* SYSLINUX: Use a downright bizarre, stateful algorithm to try
|
|
to guess the maximum transfer size. I am *hoping* this will
|
|
cut down on the number of systems for which -s is required
|
|
to work at any acceptable speed.
|
|
* ISOLINUX: Add a few more workarounds for various broken El
|
|
Torito BIOSes.
|
|
* Make sure .depend files aren't accidentally packed...
|
|
* ALL: Fix bugs in the extension-detect code; this caused
|
|
files like COMBOOT images and CD boot sectors to be
|
|
mis-identified as Linux kernels and rejected.
|
|
* ALL: Fix the return from COMBOOT.
|
|
* ALL: Do some of the early groundwork for supporting DOS
|
|
system calls in COMBOOT.
|
|
* Get rid of unnecessary "near" directives, making the code
|
|
bigger.
|
|
* PXELINUX: Put the PXE stack back in the init state before
|
|
invoking a chain-loaded NBP.
|
|
* PXELINUX: Actually found the combination of calls that
|
|
allows some (most?) PXE 2+ stacks to be unloaded from memory
|
|
properly.
|
|
* PXELINUX: Add "keeppxe" command-line option to disable
|
|
the standard unloading of the PXE stack.
|
|
|
|
Changes in 1.74:
|
|
* SYSLINUX: fix bug that would cause valid kernel images to be
|
|
labelled "invalid".
|
|
|
|
Changes in 1.73:
|
|
* Work on removing gratuitous differences between modules.
|
|
* Break up the source in common and module-specific files.
|
|
* PXELINUX: Allow chaining of other PXE NBPs.
|
|
* ISOLINUX: Allow loading "CD-ROM boot sectors".
|
|
* ALL: generalize the definition of a boot sector/NBP.
|
|
|
|
Changes in 1.72:
|
|
* PXELINUX, ISOLINUX: Fix bugs in the new core code.
|
|
|
|
Changes in 1.71:
|
|
* Fix a "brown paper bag" class bug in the new core code.
|
|
|
|
Changes in 1.70:
|
|
* Major code restructuring.
|
|
* Relax the conventional memory limits somewhat.
|
|
* MEMDISK: Set up the "version number string" pointer in the
|
|
header correctly.
|
|
* SYSLINUX: Fix, again, "the bug that won't die": the use of
|
|
the offset parameter with the SYSLINUX installer.
|
|
* SYSLINUX: Fix possible superblock corruption problem in the
|
|
SYSLINUX installer.
|
|
|
|
Changes in 1.67:
|
|
* Handle bug in the location of initrd.
|
|
|
|
Changes in 1.66:
|
|
* MEMDISK: Make compile with newer versions of gcc.
|
|
|
|
Changes in 1.65:
|
|
* ISOLINUX: Support booting disk image files (to boot DOS or
|
|
other non-Linux operating systems), *IF* the BIOS works
|
|
correctly; unfortunately many BIOSes apparently don't.
|
|
* Support Linux boot protocol version 2.03 (explicitly
|
|
specify the initrd address limit.)
|
|
* Handle small "pseudo-kernels"; images that use the Linux
|
|
kernel boot protocols but are less than 64K in size.
|
|
* MEMDISK: New subsystem; this is a driver which allows
|
|
legacy OSes to boot using an in-memory simulated disk.
|
|
See memdisk/memdisk.doc for more info.
|
|
* PXELINUX, ISOLINUX: Correctly handle files larger than 65535
|
|
blocks (32 MB for PXELINUX, 128 MB for ISOLINUX.)
|
|
* PXELINUX: Make a best-effort attempt at freeing all memory
|
|
claimed. From the looks of it, it will fail on most PXE
|
|
stacks.
|
|
|
|
Changes in 1.64:
|
|
* Limited support for hardware flow control when using a
|
|
serial port console.
|
|
* Support specifying the serial port I/O address explicitly.
|
|
* Make DOS installer hopefully behave more nicely when used on
|
|
recent Windows versions.
|
|
* Fix returning to text mode when a font has been specified.
|
|
* Attempt to detect missing serial port hardware and disable
|
|
the serial port if there is nothing there.
|
|
|
|
Changes in 1.63:
|
|
* Make the ppmtolss16 program handle color conversion more
|
|
correctly.
|
|
* Clean up "make install" target, honour INSTALLROOT if it
|
|
exists.
|
|
* SYSLINUX: Fix stack-smash bug identified by Steffen
|
|
Winterfeldt.
|
|
* Hopefully fix return-to-text-mode on some graphics cards.
|
|
* ISOLINUX: Bug workaround for Award BIOS 4.51, and perhaps
|
|
other buggy BIOSes as well.
|
|
|
|
Changes in 1.62:
|
|
* PXELINUX: Allow the DHCP server to override the
|
|
configuration file name and pathname prefix, using
|
|
"site-specific" DHCP options.
|
|
* PXELINUX: Documentation fixes.
|
|
* PXELINUX: Fix the "ipappend" option; the last two values
|
|
were reversed vs. what the kernel expected.
|
|
* Introduce a way to return to text mode once we are already
|
|
in graphics mode. This may be useful for F-key help
|
|
screens.
|
|
* Fix several bugs in the way return to text mode was handled.
|
|
|
|
Changes in 1.61:
|
|
* ISOLINUX: Support full pathname searches. Max length for a
|
|
pathname is 255 characters. As a result, only 64 "label"
|
|
statements are supported in ISOLINUX.
|
|
* PXELINUX: Max filename length extended to 63 characters.
|
|
|
|
Changes in 1.60:
|
|
* Add support for graphical splash screens.
|
|
* Add mode control characters, which allows you to control
|
|
message display output depending on output mode (text,
|
|
graphics, or serial port.)
|
|
* ISOLINUX: New program, which boots Linux from a CD-ROM
|
|
without using floppy emulation mode. See isolinux.doc for
|
|
more details.
|
|
* PXELINUX: Don't search for boot sector file types, since
|
|
they don't work anyway.
|
|
* SYSLINUX: Document the LOCK command for Win9x, and the error
|
|
dialog box for WinNT/2K.
|
|
|
|
Changes in 1.54:
|
|
* PXELINUX: Fix code for finding !PXE from PXENV+. This was
|
|
due to a spec bug; match the most recent spec since that
|
|
seems to be what implementations actually do.
|
|
* SYSLINUX: Add some smarts to the boot sector, which
|
|
hopefully should reduce the number of systems which require
|
|
stupid mode ("syslinux -s").
|
|
* PXELINUX: Document further some of the pathologies with old
|
|
PXE stacks.
|
|
* When specifying a "default" command line, no longer
|
|
automatically appent "auto". See the "DEFAULT" command in
|
|
syslinux.doc for more information.
|
|
* PXELINUX: Clean up the allocation of local socket numbers.
|
|
|
|
Changes in 1.53:
|
|
* PXELINUX: Rename pxelinux.bin to pxelinux.0, to match what
|
|
most PXE servers seem to expect.
|
|
* PXELINUX: Update the DHCP/boot server setup documentation.
|
|
* PXELINUX: Support new "localboot" option for "label"
|
|
sections.
|
|
* PXELINUX: More robust parsing of DHCP/boot server packets.
|
|
* PXELINUX: Include a small utility program "gethostip" to
|
|
compute hexadecimal IP addresses.
|
|
|
|
Changes in 1.52:
|
|
* PXELINUX: Fix bugs introduced by new A20 code. (SYSLINUX
|
|
has also been changed for code consistency reasons, but I'm
|
|
pretty sure the changes are don't care on SYSLINUX.)
|
|
* Documentation updates.
|
|
* PXELINUX: Add "ipappend" option to generate an ip= option to
|
|
the kernel.
|
|
|
|
Changes in 1.51:
|
|
* PXELINUX: Not all PXE stacks fill in the IP address for a
|
|
type 3 cached info query. Use a type 2 cached info query
|
|
for this information (only.)
|
|
* Yet another attempt at A20 coding. Now support BIOS call
|
|
15:2401 as well, and handle machines which always have A20
|
|
on separately.
|
|
* Support memory detection using INT 15h, AX=0E820h. BIOS
|
|
manufacturers have apparently gotten sloppy about keeping
|
|
INT 15h, AX=0E801h working properly.
|
|
* Don't issue <CR><LF> onto the serial port when we're doing
|
|
screen wraparound.
|
|
|
|
Changes in 1.50:
|
|
* Yet another A20-code update. It seems some "legacy-free"
|
|
machines and embedded gear simply don't have a KBC to talk
|
|
to, and that waiting for one will wait forever. Sigh.
|
|
|
|
Changes in 1.49:
|
|
* SYSLINUX: Implement a hack for BIOS drivers which hog significant
|
|
chunks of low memory during boot. (Note: PXELINUX already
|
|
had this modification. SYSLINUX does still require that the
|
|
low 512K is available; PXELINUX requires 384K. Machines
|
|
with a physical memory hole in the low 640K cannot boot
|
|
Linux no matter what.) Depending what the reason is for the
|
|
memory hole, a new kernel (2.4.0-test3-pre3 or later) may be
|
|
required.
|
|
* SYSLINUX: Default installer binary now compiled against
|
|
glibc 2.1. If this is inappropriate for your system and you
|
|
still want to use the offical version of SYSLINUX, please
|
|
follow the instructions in "distrib.doc" to rebuild the
|
|
installer.
|
|
* SYSLINUX: Linux installer program now supports -o <offset>
|
|
option which does a loopback mount with the
|
|
-o loop,offset=<> option. Useful to run SYSLINUX on an
|
|
individual partition of a whole-harddisk image.
|
|
* Include the source code to a Master Boot Record (MBR)
|
|
functionally equivalent to the one installed DOS except it
|
|
includes EBIOS support, and should be resistant to geometry
|
|
changes. The MBR code is public domain.
|
|
* PXELINUX: Fix "double p" bug: if the tftp prefix was null,
|
|
all filenames would get a "p" preprended, e.g.
|
|
"ppxelinux.cfg" and "pvmlinux".
|
|
|
|
Changes in 1.48:
|
|
* PXELINUX: Workaround for PXE ROMs based on the Intel PXE PDK
|
|
3.0 build 071 and earlier: missing !PXE structure pointer.
|
|
* PXELINUX: Handle larger BOOTP/DHCP packages.
|
|
* PXELINUX: The command line passing was broken; fix.
|
|
* PXELINUX: Make COMBOOT images work.
|
|
* PXELINUX: Documentation on how to make booting work using
|
|
the PDK 3.0-derived clients, which aren't so generous as to
|
|
allow booting with only "PXEClient" specified.
|
|
|
|
Changes in 1.47:
|
|
* PXELINUX: RFC 1123 states that a TFTP implementation MUST
|
|
use adaptive timeout, "at least an exponential backoff of
|
|
retransmission timeout is necessary." Implement a very
|
|
simple exponential backoff for retransmits.
|
|
* PXELINUX: Updated documentation, including pointer to new
|
|
TFTP server.
|
|
* PXELINUX: When sending ERROR due to bad OACK, use the proper
|
|
destination port number (why are TFTP port numbers so odd?)
|
|
* PXELINUX: If the boot dies in the middle somewhere,
|
|
eventually give up and reset the machine (unattended
|
|
operation.)
|
|
|
|
Changes in 1.46:
|
|
* New program PXELINUX to do network booting using a
|
|
PXE-compliant (Pre-Execution Environment) network booting
|
|
PROM. See pxelinux.doc for details.
|
|
|
|
Changes in 1.45:
|
|
* Serial console support. See syslinux.doc for details.
|
|
|
|
Changes in 1.44:
|
|
* Change HIGHMEM_MAX to 38000000h to (hopefully) avoid the
|
|
kernel stepping on it; 3f000000h was apparently a higher
|
|
limit than the kernel used!
|
|
|
|
Changes in 1.43:
|
|
* Add sys2ansi.pl script to display the contents of a
|
|
colorized SYSLINUX file.
|
|
* Changed the io_delay once again, after a report that the
|
|
old delay port causes hangs on some systems.
|
|
|
|
Changes in 1.42:
|
|
* Frob the "fast A20 gate" port as well as the keyboard
|
|
controller; will this help systems with problems?
|
|
* Be even more paranoid about A20, unfortunately even this
|
|
seems to be not paranoid enough... what I don't understand
|
|
is that if there is hardware out there *this broken*, how
|
|
can it run Linux at all? Report an error message rather
|
|
than hang forever if A20 is stuck.
|
|
* Include some intermediate files in the distribution, plus
|
|
provide a "make installer" target for distributors to relink
|
|
the install programs only. I would prefer the syslinux boot
|
|
loader proper to be "binary clean" for debuggablity -- use
|
|
"make clean ; make installer" to rebuild the installers only.
|
|
|
|
Changes in 1.41:
|
|
* Don't get confused by directories, volume labels, or VFAT
|
|
long names.
|
|
* Use INT 15h, AX=0E801h to query memory size before trying
|
|
INT 15h, AH=88h. This not only provides more headroom
|
|
between the kernel and the initrd on large-memory machines,
|
|
but it appears some recent BIOSes actually have started
|
|
returning garbage for the AH=88h (older) call.
|
|
* Trust high memory beyond the 15 MB mark if the user has
|
|
specified it, or if obtained with INT 15h, AH=0E801h (with
|
|
no memory holes above 1 MB.)
|
|
|
|
Changes in 1.40:
|
|
* Increase A20M delay and put in a test to avoid problems on
|
|
certain IBM Thinkpads (thanks to Donnie Barnes of RedHat
|
|
for vital info on this one.)
|
|
* Support COMBOOT style boot command images.
|
|
* Support chain loading (foreign operating systems, e.g. DOS).
|
|
* Include a new "copybs" DOS utility to copy a boot sector to
|
|
a file (under Linux, use "dd".)
|
|
* Fix the DOS installer to work for disks over 32 MB.
|
|
* SYSLINUX should now handle disks with more than 65536 tracks.
|
|
|
|
Changes in 1.37:
|
|
* Fix a bug that caused "label" statements in syslinux.cfg to
|
|
not be handled properly.
|
|
* Updated the documentation. Among other things, we now allow
|
|
up to 128 "label" statements.
|
|
|
|
Changes in 1.36:
|
|
* Fix for booting old (pre-initrd) kernels.
|
|
* It seems at least some versions of OS/2 doesn't set up all
|
|
the fields in the superblock correctly. Account for that.
|
|
* Fix bug that caused boot failure when using the mem= option.
|
|
|
|
Changes in 1.35:
|
|
* Loading from partitions now should work properly. (Actually
|
|
tested, this time. You should even be able to dd a floppy
|
|
to a partition and boot from it.)
|
|
* Removed large workaround code for an alleged ancient BIOS
|
|
bug I have never actually seen. The -s option should work
|
|
on those machines, anyway.
|
|
* Support for simple keyboard remappings, same as used by
|
|
LILO (once again to support localization.) The program
|
|
keytab-lilo.pl from the LILO distribution included to
|
|
generate such maps.
|
|
* Added a "safe, slow and stupid" (-s) option to the
|
|
installers. This option will lobotomize the boot sector to
|
|
hopefully work on even very buggy BIOSes.
|
|
|
|
Changes in 1.34:
|
|
* Ability to load a VGA font on bootup (for localized Linux
|
|
distributions.)
|
|
|
|
Changes in 1.33:
|
|
* Bug fix in the Linux installer.
|
|
* Added a workaround for a bug in certain AMI/Intel BIOSes
|
|
when booting from CD-ROM.
|
|
* Documentation changes.
|
|
|
|
Changes in 1.32:
|
|
* FAT16 filesystems are now supported.
|
|
|
|
Changes in 1.31:
|
|
* Now compiles under Linux, using NASM, rather than using
|
|
Turbo Assembler under DOS. See http://www.cryogen.com/Nasm
|
|
for information about NASM.
|
|
* Linux-hosted SYSLINUX installer, as well as a
|
|
rewritten DOS installer (now is written in assembler, so we
|
|
don't need Turbo C.)
|
|
|
|
Changes in 1.30:
|
|
* Added support for loading bzImage and initrd loading, and made
|
|
SYSLINUX new-setup-code aware (SYSLINUX 1.30 id=0x31).
|
|
* Added LILO-style kernel labels; see the LABEL and IMPLICIT
|
|
keywords in README file.
|
|
* Added support for colorization of intro and help screens.
|
|
* The vga= option is now handled correctly.
|
|
* Massive rewrite of large chunks of the code in order to
|
|
support the first two new features.
|
|
|
|
Changes in 1.20:
|
|
* Added simple online help at the "boot:" prompt.
|
|
* Removed 2880K image as I no longer have access to such a
|
|
floppy drive. (Donations accepted!!)
|
|
* Decided to distribute the source in a subdirectory rather
|
|
than in a nested zipfile.
|
|
|
|
Changes in 1.11:
|
|
* Removed a sanity check which would cause booting to fail on
|
|
Phoenix BIOS version 4.03. Apparently this BIOS is buggy.
|
|
|
|
Changes in 1.10:
|
|
* Added configuration file SYSLINUX.CFG. This file contains all
|
|
configurable options, and can be edited from any OS which can
|
|
access an MS-DOS filesystem; there is no longer a need to run
|
|
SYSLINUX.EXE except to write the boot sector.
|
|
* Default command line now given by "default" line in config
|
|
file.
|
|
* LINUXMSG.TXT and BOOTMSG.TXT hard-coded file names replaced by
|
|
"display" and "prompt" lines in config file.
|
|
* LILO-style option appending now supported ("append" line in
|
|
config file).
|
|
* Prompt timeout is now supported ("timeout" line in config
|
|
file). The timeout is cancelled when anything is typed on the
|
|
command line.
|
|
* Pressing <ESC> or <Ctrl-C> at the Loading... stage now aborts
|
|
the kernel loading in progress and returns the user to the
|
|
boot: prompt.
|
|
* The installer now automatically sets the READONLY flag on
|
|
LDLINUX.SYS.
|
|
* Added 2880K disk image.
|
|
|
|
Changes in 1.03:
|
|
* Fixed bug that would prevent booting from double-density
|
|
floppies and other DOS filesystems with multiple sectors per
|
|
cluster.

* Added 720K disk image.
|
|
* Changed default kernel name on disk images to LINUX.
|
|
|
|
Changes in 1.02:
|
|
* Fixed bug that would garble the command line on recent kernels
|
|
with more than 4 sectors of setup code (this wasn't really a
|
|
*bug*; rather, a kernel change broke the code. Unfortunately
|
|
the Linux boot interface is still sorely undocumented).
|
|
* Added BOOTMSG.TXT file support (message file which does not
|
|
force display of the boot prompt).
|
|
|
|
Changes in 1.01:
|
|
* Fixed bug on some (most?) 386 BIOSes would require two boot
|
|
attempts.
