You're right, I not only don't see any SCSI drives there, I don't see
any SCSI interface cards at all.

There is a so-called Sun-2 SCSI interface, which SunOS calls the "sc"
and usually comes in this sort of adapter, that puts the SCSI bus on
the P2 backplane connector and must go in a specific backplane slot
(eg, slot 7 on the 12-slot cardcages) because only that slot has the P2
connector appropriately wired.  Since you've got this style of adapter,
you probably have an sc.

NetBSD does not support the sc, AFAIK.  I have a (sun3 port) driver
partially written and I intend, someday when I have some spare time
:-(, to work more on it.  I understand a few others are in much the
same position.

Now, it's possible you don't have an sc; it is possible to put an si
into the SCSI-on-P2 adapter.  (I know this 'cause I've done it.)  But
if you'd done that, (a) you wouldn't have to ask the questions you're
asking, and (b) it would probably Just Work.

If you can find a SunOS kernel (don't need more than the kernel), try
booting it and see what it calls that card.  If it reports "sc0 at...",
you've got an sc.  (The alternative would be "si0 at...".)
