It is possible but not quite probable: it works very well with the onboard
810 chip, and it works (same kernel version) on Intel.

I'm in the process of upgrading it; I've just stopped burning a defective
floppy :(
I'll try AlphaBIOS too.
(not a great idea upgrading my firmware at 1 am, is it? :)

Uhm. Of course we don't need no INT 13 emulation or the like, but... some
init to the hardware by the manufacturer wouldn't hurt.
And, AlphaBIOS has an option about SCSI BIOS emulation (none/some/all);
didn't test it yet.

In the motherboard BIOS setup (equivalent to the one in SRM or AlphaBIOS).
Currently I don't really know wether the PC mb implements PCI parity or not
(but this isn't the problem, I suppose).

I had a working potato installation on a small disk connected to the 810;
then I bought the new controller and disk and added them (still booting
from the 810); currently I moved the new ctrl/disk to the PC and use them
via NFS, having boot and root on the small disk.

I'll post a report after upgrading the firmware.

Ciao, William
