    • Keyboard Controller is not dumped

    • CANCEL Revision ?1? BIOS (08/26/91) is dumped but at half size, and in a messy way. A protected mode program will be required to fully dump it.
    • Keyboard Controller is not dumped
    • Revision 1 BIOS (04/24/81) is not dumped, but a disassembly exists on Rich Cini's site: http://highgate.comm.sfu.ca/~rcini/files/PCBios.ASM
    • ACCEPT Revision 2 BIOS (10/19/81) is dumped, verified, and in MESS

    • ACCEPT Revision 3 BIOS (01/10/86), Model XT-089, is dumped and in MESS. AKA 'enhanced XT', it has enhanced KB support IN SOFTWARE (yikes), also has 3.5” drive 720k support.

    • ACCEPT Revision 3 BIOS (11/15/85, AT model 319 or 339, 3.5” drive, 30MB HDD, locked to <8.3Mhz or <12Mhz? or maybe just >6Mhz?) is dumped, verified, and in MESS.
