Yup, that sounds about right.

Yes, the port address of 330 is hardcoded into the bios.  Interactive's
aha driver doesn't care about this of course; you can set it up almost
anywhere.  The problem only comes in booting the damn machine from the
SCSI disk.  If the card is not at port 330, you can't use the SCSI bios
to boot.

Probably your best bet.
