So the motherboard has both 50-pin and 68-pin SCSI connectors on it, and
your using the 68-pin only, correct?

How else did you expect to find it? I'm not sure of any other methods..

How did it fail? Any messages to refer to, like from another VC? (try
alt-f2 and alt-f3 for more information)

I'm not aware of any partitioning problems you could possibly make that
would cause scsi timeout or queue full errors.
Have you tried setting the card back to the default settings? Are you sure
the disk you have supports the wide negotiation and data rate you've
configured it at?
Make sure you have termination correct.
Create DOS partitions first, with DOS's fdisk, make it active, format it,
then install Linux.
