SCSI-2 CDROM
Any SCSI-2 (but NOT SCSI-2 Wide) drive *should* work with the A2091, especially
if you have the most recent (7.0) A2091 ROMs and probably even if you don't.
A SCSI-2 drive is supposed to act just like a SCSI-1 drive except that it knows
what to do if you send it SCSI-2 commands. The A2091 won't send it SCSI-2
commands, and the SCSI-1 commands it sends still act the same.
