Exactly why would notifying the kernel or linux that the
SCSI ID of the card is 7 be necessary? I have an Adaptec
1510A (no BIOS) and I used 'insmod aha152x io=0x340 irq=9'
(I imagine that modprobe would have worked too) I added a
line like that to /etc/modules as well (the 686 version of
2.4.18). I'm not saying that's wrong, I just don't see why
it is necessary.

If the card has a BIOS, have you tried not doing anything
and just letting it boot up? I also have a 1542 (or 1540) on
a different machine and between the BIOS and the kernel it
seems to sort itself out (mind you that is with a 2.2 kernel
on a potato box and the system is booting from an attached
drive), as does my 2940UW on this machine (again, booting
from an attached SCSI drive, and, yes, there are two SCSI
cards on this box :) ).

Even though you were given the settings I'd still take a
look at the jumpers to see if they're correct. Also, many
network cards (both PCI & ISA) seem to like irq 10, so check
for possible irq conflicts (I think the factory default for
Adaptec ISA SCSI cards was irq 9, for PCI it seems to be 11).
