Any PCI ATA controller will work, and that machine probably has ISA slots
so you could use an ISA ATA controller if you were desperate.

I put my P90 out to pasture since once the 2GB disk dies in it I'll have
to use flash media to get a disk the onboard controller will support.  So
I replaced it with a small fanless Soekris :)

AFAIK the RZ1000 bug was that it would corrupt data to the slave channel
if the primary channel was also active.  If you only have one device then
you may not be able to reproduce it.

Do you have verbose boot output from the non-working 5.x boot?
