I recently obtained a Sun 3/80 which I am trying to set up with NetBSD.
It formerly was used as a diskless SunOS system.

As can be expected, the NVRAM battery is dead. So, while I wait for the
new one to arrive, I thought I'd try to do a tape install. (The ROM
revision is 3.03 which, IIRC, can boot a 150mb tape.)

I've installed an old HP C2333S drive inside the pizza box and connected
up my old Sun Archive 150 tape drive.

When I do a "b st()", however, all I get is the response:

	st: Device not found.

No variation of "st()" seems to make a difference. FYI, my tape is at ID
4.

On a whim, I decided to try to tell it to boot from the unformatted disk
with a "b sd()". This elicited a similar response, even though the disk
drive is set for ID 0.

So, my questions:

1) Is there any reason that the dead NVRAM might keep me from booting
from tape?

2) Any special setup considerations which I might have missed? I believe
I have everything terminated correctly.

3) Are the eXtended diags supposed to offer a SCSI test option? Mine do
not?

4) Am I, as I fear, looking at a dead SCSI subsystem?

Thanks in advance...
