Hi!
Have You checked that the BIOS IS enabled on the card; if disabled
the driver won´t be able to initialize the card using its BIOS-probing
feature. Another problem could be the fact that the card was taken from
an Alpha. These architectures adresses the low byte opposed to the
X86 which adresses the high byte first. This COULD cause problems
with SCSI-cards, making them unresponsive. If this is the case, You
might want to look through Your manual for an eventual pin to change this
in Your favour. However, since the Alpha seems unable to deal with the
card this may prove irrelevant. ;-)
Good Luck!
Yours Truly,
Henrik
