Of course, if this is an IDE or SCSI drive and
controller, the=20
controller should have its own BIOS to work in a setup like this. If=20
it doesn't, you need to find one unless you're into BIOS hacking.
Uh? Had these multi-id controllers have their own BIOS extension? My
I was wondering about that too. The IDE interface is essentially the same
at the I/O port level as the original PC/AT hard disk controller, so it
whould work with the standard motherboard BIOS.
FWIW. I have an IDE hard disk in this PC. The controller is a
slightly-hacked one using a few TTL chips and an address decoder PAL.
There is no BIOS extension ROM, the original IBM BIOS talks to it just
fine. I did have to modify the drive parameter table (IBM didn't have
user-definded drive types on the PC/AT), but given the TechRefs that was
a trivial job.
