The 1542CF works, but it is an ISA-bus card. I've heard Ultrastor
went belly-up.
What kind of bus do you have? If you have EISA or VLB, I would
*strongly* suggest staying away from ISA bus cards. EISA and VLB will
operate the bus at 33 to 40 MHz 32-bits at a time, where ISA generally
runs at 8 MHz 16-bits at a time. Plus, you must use bounce buffers
(slower) with ISA cards if you have more than 16 meg of RAM since the
ISA bus won't adress more than 16 meg, where EISA and VLB can address
up to 4 gig of memory directly.
The controller brand generally recommended these days is BusLogic.
They're cheaper and the support is better than Adaptec. Plus, they
have compatible controllers for almost any bus design. Stay away from
ISA if at all possible. I run an EISA-bus SCSI-2 BusLogic bt747s in
my machine, and it's a really great card.
Adaptec 28xx controllers are *not* supported.
