1 2 Change log for eltorito.asm, by Bart Lagerweij 3 4 Jun 25, 2009 - License source code under the MIT license 5 6 Jun 6, 2002 - v1.2 7 Eltorito.sys does now also finds the correct driver number for the booted CD-Rom 8 on a Dell PC with very buggy BIOS. It does not clear the carry flag after a 9 succesfull call to int13/ax=4b01h call. Other PC's also using Phoenix BIOS 10 version 1.10 A14, or alike maybe also benefit from this "workaround". 11 12 Mar 9, 2002 13 - All read requests are now retried 5 times. 14 - Bug fix, had... 15 cmp ax, 3FFFh ;Too large? 16 ja ReadLBad ;If yes 17 seperated from... 18 mov ax,es:[bx+18] ;Get number of sectors to read 19 mov word ptr [SpecPkt+2],ax 20 so, it was checking "wild" ax values... 21 - Some cleanup and small changes 22 - The tracers give trouble when using SHCD.. 23 - Reverted proc ReadL back to Rev. 0.15BETA 24 25 Mar 5, 2002 26 - Bug fix, when changing CD media some machines would "hang" in the PriVolDesc 27 routine. 28 - Added printing of TRACER characters to trace the bug above 29 - Major cleanup and now using ASCIIZ strings 30 31 May 9, 2001 32 - Fixed a "pad devicename with spaces" bug, this only happened when a device 33 name was used with less than 8 characters, for example, "MSCD000" became 34 "MSCD000(" 35 - Bug fix, when eltorito.sys was called with invalid command line parameters, 36 garbage was printed and sometimes followed by "system halted" that has been 37 there since the very first version of eltorito.sys. I know that because I 38 had the bug back then. When loading eltorito.sys using a device loader, 39 for example "device.com eltorito.sys /test:123" garbage was printed instead 40 of "No device name found." "driver not installed". 41 Changed the error message to include a "usage" string. 42 43 May 8, 2001 44 - If diskemu.bin is loaded eltorito.sys uses the drivenumber from diskemu 45 A call is made to "diskemu/Get status" (INT13/AX=5400) and the drivenumber is returned in CL 46 This should fix boot problems on Dell PCs (YES!) 47 When diskemu.bin is not loaded, eltorito still loops all drive numbers using eltorito calls. 48 - Removed "press Escape..." 49 - When the Alt-key is pressed (and holded) more info is printed and eltorito.sys halts 50 51
