Preliminary driver by Grull Osgo
TODO:
- gammagic: throws a CONFIG.SYS error in CD_BALLY.SYS right away,
checks the disc drive in bp 6b26 subroutine against a 0x0258 value after sending an
identify packet device command (shutms11 ATAPI returns 0x0208).
Seems to be a Toshiba XM-3301 CD/DVD drive according to RAM buffer.
- gammagic: throws a CONFIG.SYS error in CD_BALLY.SYS right away.
Checks the disc drive in bp 6b5b subroutine against a 0x0258 status after sending an
identify packet device command (ATAPI returns 0x0208) expecting a ready + device fault?
Drive should be a Toshiba XM-3301 CD/DVD drive according to RAM buffer.
- gammagic: requires Voodoo and a ESS Solo-1/Maestro PCI card family to boot;
- gammagic: can't find D: if above is skipped after detecting ESS and Voodoo cards.
- 99bottles: "not High Sierra or ISO9660", likely bad (disc-at-once with one track?)
- Identify and hookup proper motherboard BIOS
Should be a m55hipl with CD-ROM as bootable option, m55-04ns and m55-04s doesn't cope with
this requirement, dump mentions using El Torito specs at offset 0x8801.
Notice that CD_BALLY.SYS driver mentions using an Adaptec AHA-154x SCSI, is the CD drive actually
connected there rather than being BIOS responsibility?
- Missing 68k dump portion.
Very unlikely it transfers code from serial, and CD-ROM dump doesn't have any clear file that
would indicate a code transfer or an handshake between main and sub CPUs;
