SYSLINUX 3.62 released
Hello all,

I have just released SYSLINUX 3.62. This is almost identical to
3.62-pre16, with a small number of changes to the Makefiles and

The focus of this release has largely been removing build-in
limitations as much as possible. Quite a bit of work has gone into

I'd like to specially thank my employer, rPath Inc.; I've spent a lot
of time on this I wouldn't have been able to do without their


Changes in 3.62:
* Clean up garbage after "aborted." message.
* Clean up 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.
Title: syslinux
Version: 3.62
Entered-date: 2008-03-01

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

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.

Bypass pixel conversion when the output format is BGRA32
Set the window size to 2 GB for linear framebuffer
VESA: move debugging code to separate header file
VESA: Minor cleanups

Slightly simpler to use interface to simple_pm_call
Don't close the A20 gate; leave it open
hello.c: print arguments, no input section
Put virtual kernels (CLI labels) in high memory
If we're showing a scrollbar, always show at least one unit

memdump: fix typo
Submenu support: development snapshot
Actually implement syslinux_ipappend_strings()
Actually implement strnlen()
submenu snapshot: it compiles now...
[v]rsprintf(): actually set the return pointer...
refstr_get(): handle NULL, force inline
Simple menu: use refstrings consistently; now works again
refstr: handle NULL in refstr[n]dup()
simple menu: first cut at working submenus
simple menu: The use of realloc() requires indirect pointers
Document hierarchial menus so far...
Allow an included file to be treated as a submenu.
Allow MENU LABEL <-> MENU TITLE for submenus to work both ways
Set m->title for both root and submenus
Add dependency generation for the simple menu system
Add dependency generation for com32 modules.
Add dependency generation for com32 samples.
com32: remove dependency files for "make tidy"
Whitespace cleanup...
When entering a new menu, go to the default entry for that menu.
Add support for MENU EXIT; no marker for MENU GOTO
simple menu: remember the cursor position on a per-menu basis
Fix the scrollbar handling for insanely huge menus
simple menu: fix the handling of '+' and '-' given disabled entries
Make sure color directives get attached to the proper menu.
Fix MENU TITLE -> MENU LABEL inheritance
"begin Ymodem download" is supposed to be an imperative...
realloc(): better implementation allowing in-place growth
realloc(): try to protect a block in the path of a growing object
NEWS: Document Bruce Robson's Adaptec bug fix
Fix the handling of hotkeys in MENU LABEL on submenus
Allow MENU EXIT to specify a menu tag
