README.gfxboot Normal file

gfxboot is now loaded via a COM module. If you used a line like
gfxboot bootlogo
before in isolinux.cfg or syslinux.cfg, change this to
ui gfxboot.com bootlogo
and add /usr/share/syslinux/gfxboot.com to your boot directory (the one
where the config file is).
This also means that gfxboot now works with other syslinux variants like
pxelinux or extlinux, too.

From: Jeff Mahoney <jeffm@suse.com>
Subject: [PATCH] Alias "gfxboot" to "ui gfxboot"
This patch allows older configs using the SUSE implementation of
syslinux + gfxboot to continue to use the "gfxboot" keyword.
It is intentionally undocumented since it should not be used
in new configurations.

Wed Jun 10 11:59:54 CEST 2009 - snwint@suse.de
- update to version 3.82
* Lots of bug fixes.
* Simple menu: make ONTIMEOUT work with MENU HIDDEN.
* PXELINUX: handle TFTP servers which have extra NULs at the
end of an OACK packet.
* 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.
* isohybrid: fix the -partok logic for loading from a partition.
* isohybrid: add a variety of options, and a help message.
* isohybrid: fix problem with images over 2 GB in size.
* 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.
* Don't hang trying to boot a "menu quit" label from the CLI.
* Fix problem with boot-once "sticking" on some BIOSes.
-------------------------------------------------------------------
Wed Apr 22 12:54:53 CEST 2009 - snwint@suse.de
- gfxboot: usage has changed; see README.gfxboot for details
- update to version 3.75
* Lots of bug fixes.
* 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.
* Suppress the Loading ... message if "quiet" is specified on
the kernel command line.
* 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.
* 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.)
* 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.
* 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.
* Tab display of labels, based on a patch from Sebastian
Herbszt. Can be disabled with the NOCOMPLETE configuration
command.
* 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.
* chain.c32: lots of new options added
* 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.
* 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.
* SYSLINUX: VFAT long filename support.
* Add an experimental MBR for GPT partition tables.
- Update to 3.81
- Lots of bug fixes
- Support for disk/CD hybrid images
- Integrated gfxboot support
- Added support for deprecated 'gfxboot' param
- Split into 4 packages

- Integrated gfxboot support
- Added support for deprecated 'gfxboot' param
- Split into 4 packages
* Tue Nov 04 2008 snwint@suse.de

* Fri Oct 17 2008 olh@suse.de
- add ExclusiveArch x86 x86_64
* Thu Oct 16 2008 snwint@suse.de
- minor serial line patch fix (bnc #436034)
* Wed Sep 10 2008 snwint@suse.de
- reworked serial line patch (removed SERIALLINES)
* Thu Sep 04 2008 snwint@suse.de
- added SERIALLINES config option to listen on up to four
serial lines (fate #301595)
* Mon Apr 28 2008 snwint@suse.de
- give more memory to gfxboot code
* Mon Apr 14 2008 snwint@suse.de
- update to version 3.63
* Lots of bug fixes.
* Handle command lines up to 2047 characters, the current
Linux kernel limit.
* Support MD5, SHA256 and SHA512 encrypted passwords.
* MEMDISK: Turn on EDD support by default.
* Add a new INCLUDE command to the core syslinux parser.
* It is now supported to load a different configuration file
with the CONFIG keyword.
* MENU AUTOBOOT, MENU TABMSG, MENU PASSPROMPT allows
internationalization of menu messages.
* 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.
* Simple menu system: new "MENU HIDDEN" option to not display
the menu unless the user presses a key.
* Add "menu separator", "menu indent", "menu disabled"
(see README.menu).
* SYSLINUX: Support subdirectories.
* PXELINUX: Press Ctrl-N at the boot prompt to read out the
network info.
* 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.
* EXTLINUX: boot-once support (--once, --clear-once, and --reset-adv)
* 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.

* 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.
* 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.
* PXELINUX: Fail (and eventually reboot) if no configuration
file was found.
