Thanks Don, Jeff and others who gave me great advice. Here's the
status:

1. Installed 80GB Seagate IDE drive
2. Installed Solaris 8
3. Flashed the OBP to version 3.31

Everything working fine at this point... CPU, cdrom, floppy, monitor,
and keyboard.

O.K.

4. Set the DIP switches to all off for Channels A and B on the
375-0005 SCSI card and inserted it in a PCI slot.

Reasonable.

On boot up, the system freaks out again, same as before... disables
the monitor and keyboard and can only be controlled through the ttya
port. Boot up shows the same message as before:

Data Access Error
ok

I tried it in two different PCI slots. I did not re-seat the PCI
riser board, but it appears to be well-seated and bolted in place.

Hmm ... the FEH (Field Engineer's Handbook) says (among other
things):

6. Do not install spacers under PCI riser boards installed in systems
built after June 2000 with EZ label Service Code C Series 3.

(whatever that means.)

Jeff said he's been using this SCSI card in Ultra 10s with no problem,
so I'm really puzzled why I'm having so much trouble. I'm starting to
think I have a bad PCI riser card, or a bad SCSI card. There's a bank
of four jumpers on the riser card that are all set to 1-2. I assume
that's correct. I can't find anything on the Internet about those
jumpers.

The same FEH page says the following:

JP1 PCI1 JSCAN Ring End Point - 1-2 = Pass, 2-3 = end
JP2 PCI2 JSCAN Ring End Point - 1-2 = Pass, 2-3 = end
JP3 PCI3 JSCAN Ring End Point - 1-2 = Pass, 2-3 = end
JP4 PCI4 JSCAN Ring End Point - 1-2 = Pass, 2-3 = end

with JP1 being the top row of pins, and pin 1 being the right-most. So,
all are set to be the Ring End Point

Any more suggestions would be greatly appreciated.

Do you have *any* generic PCI cards which you can try in the
riser? I've found a quad USB 2.0 card to work in the Ultra-60 -- but to
cause reboots with a Sun Blade 1000. You might try any PCI card in the
Ultra-10 -- better if you know that it is a Sun Blessed card, but even
if not, you can at least see whether it also gives the same problems.

Looking at the FEH drawing of the PCI riser card, I don't see,
any chips, so I think that it is more likely that something about the
SCSI card is bad. I've had a quad fast ethernet Sbus card perform
similar system lockups, so a bad card *can* do it.

The same page also references the following documents:

Sun Ultra 5/10 Service Manual, 805-0423, 805-7763, and 805-7764
Sun Ultra 5/10 Product note, 805-3647-10
Sun Ultra 10 ShowMe How Multimedia Documentation, 704-5983.

You can probably download at least the first two from Sun's web
site, though I have no idea about the third item.

Note that the 375-0005 card is without FCode -- and I'm using
such cards without FCode, so that should not be the problem. Without
FCode may also mean without a chip to store the FCode in. And, the FEH
page for the 375-0002 includes the A22 (Ultra-10) in the list of
machines for which it is suitable.

But -- a *bad* copy of the card could still cause problems.

Good Luck,
DoN.
