Change log for eltorito.asm, by Bart Lagerweij
Jun 25, 2009 - License source code under the MIT license
Jun 6, 2002 - v1.2
Eltorito.sys does now also finds the correct driver number for the booted CD-Rom
on a Dell PC with very buggy BIOS. It does not clear the carry flag after a
succesfull call to int13/ax=4b01h call. Other PC's also using Phoenix BIOS
version 1.10 A14, or alike maybe also benefit from this "workaround".
Mar 9, 2002
- All read requests are now retried 5 times.
- Bug fix, had...
cmp ax, 3FFFh ;Too large?
ja ReadLBad ;If yes
seperated from...
mov ax,es:[bx+18] ;Get number of sectors to read
mov word ptr [SpecPkt+2],ax
so, it was checking "wild" ax values...
- Some cleanup and small changes
- The tracers give trouble when using SHCD..
- Reverted proc ReadL back to Rev. 0.15BETA
Mar 5, 2002
- Bug fix, when changing CD media some machines would "hang" in the PriVolDesc
routine.
- Added printing of TRACER characters to trace the bug above
- Major cleanup and now using ASCIIZ strings
May 9, 2001
- Fixed a "pad devicename with spaces" bug, this only happened when a device
name was used with less than 8 characters, for example, "MSCD000" became
"MSCD000("
- Bug fix, when eltorito.sys was called with invalid command line parameters,
garbage was printed and sometimes followed by "system halted" that has been
there since the very first version of eltorito.sys. I know that because I
had the bug back then. When loading eltorito.sys using a device loader,
for example "device.com eltorito.sys /test:123" garbage was printed instead
of "No device name found." "driver not installed".
Changed the error message to include a "usage" string.
May 8, 2001
- If diskemu.bin is loaded eltorito.sys uses the drivenumber from diskemu
A call is made to "diskemu/Get status" (INT13/AX=5400) and the drivenumber is returned in CL
This should fix boot problems on Dell PCs (YES!)
When diskemu.bin is not loaded, eltorito still loops all drive numbers using eltorito calls.
- Removed "press Escape..."
- When the Alt-key is pressed (and holded) more info is printed and eltorito.sys halts
