Starting with 1.47, changes marked with SYSLINUX/PXELINUX/ISOLINUX
|
|
apply to that specific program only; other changes apply to all of
|
|
them.
|
|
|
|
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.
