Syslinux 4.00 is the first of a set of major code restructuring
releases.  The single biggest new features are btrfs and ext4 support,
and support for disks larger than 2 TiB.

Huge thanks to:

- Intel, for sponsoring mine, Alek Du's and Feng Tang's work on
  Syslinux (Feng's work will be included in a subsequent release);
- Shao Miller, Gert Hulselmans, Erwan Velu, Gene Cumm, and Thomas
  Bächler for all your work and especially your work during the last
  productization rush.
- Liu Aleaxander, Pierre-Alexandre Meyer, Steffen Winterfeldt,
  Sebastian Herbszt, Ferenc Wagner and Paul Bolle for major
  development work.
- Everyone else who have contributed or tested!

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.

Title:		syslinux
Version:	4.00
Entered-date:	2010-06-28

Description:	SYSLINUX is a collection of boot loaders for the Linux
		operating system which operates off Linux ext2/3
		filesystems, MS-DOS FAT filesystems, network servers
		using PXE firmware, or from CD-ROMs.  The FAT
		filesystem version can be installed from DOS, NT, or
		Linux.

		It includes a sophisticated API for add-on "COM32"
		modules, including a significant subset of the
		standard C library.

		It also includes MEMDISK, a tool to boot legacy
		operating systems from nontraditional media like PXE
		or CD-ROM.

		This version includes gPXE, to allow accessing network
		files via other protocols than TFTP.
