Fo me the machine does an Oops every time I try to access ANY device on the
BT-930, including an HP 4c scanner.

Yes, BT-950

Yes, but that will change in a few days. Currently I have a IDE CD-ROM but
the SCSI CD-ROM just showed up, another reason to fix my BT-930.

I believe so, and I'll be freeing another IRQ when I disable IDE. Don't PCI
cards support IRQ sharing, I remember reading that the BusLogic cards do.
Also I've seen somethign about disableing the ISA port address, could that
apply to this problem?

Yes, Tyan MB, Dual Pentium 200Mhz MMX

Tyan Tomcat

I have an IBM PC750 running 2.2.5-15 (stock RH6) with a BT-930 hooked to the HP
4c and a 4mm DAT, and it works great, use SANE over the network as I can't get
the BT-930 to work in the server.
