Different geometry on the CMD controller.

Again, might be a mapping mismatch, particularly when the HD was run off
another (non-Adaptec) HA before. Anyway, a 1542 is not a good choice for
a modern mo/bo, ISA busmastering just does not work very well behind a
PCI-ISA bridge. Additionally, have you checked whether the termination
is correct?

Apparently the 1542 ends up first in the booting order.

Number one: Stuff in Promise Ultra100TX2. Number two: Do you really need
the SCSI stuff? The 1542 is only fast SCSI after all, veeery long in the
tooth even compared to the southbridge IDE. An attached disk is not
likely to be very speedy either. If you want to keep it, consider
investing into a PCI SCSI HA (something LSI/Symbios based that does
U-SCSI would do fine). You can usually turn off the booting support.
