First, upgrade to a stock 2.0.33 kernel.
It seems that Adaptec has slightly changed the bus identifiers
for that card. I should be getting a AHA-1480 CardBus controller
(7860-based) soon, and hopefully I'll be able to scrounge up
another drive for my laptop (not enough room for Linux), so I
plan on adding support for this controller.
In the mean-time, you can try changing the driver to see the
controller as a narrow bus, by changing:
switch (sblkctl & SELBUS_MASK)
{
case SELNARROW: /* narrow/normal bus */
p->scsi_id = inb(p->base + SCSICONF) & 0x07;
to:
switch (sblkctl & SELBUS_MASK)
{
case 0x10:
case SELNARROW: /* narrow/normal bus */
p->scsi_id = inb(p->base + SCSICONF) & 0x07;
in aic7xxx_register() in linux/drivers/scsi/aic7xxx.c. Depending
on what kernel you have, it is approximately line 4936.
Report back to me how you make out. BTW, aic7xxx related questions
should be directed to the aic7xxx mailing list (send email to
MajorDomo@FreeBSD.org with no subject and signature, and a message
body of only "subscribe aic7xxx").
