Yes, this is correct. Manufacturer 0x0000, product 0x0002.

and, it also probes the Mikrotek ScanMaker E3 scanner and Philips
CDD2600 CD-R drive correctly on that Acorn card.

Excellent. Now we have a workaround for the PowerROM.

Will NFS be able to improve the speed? I will set up another NetBSD box
with a 4x2GB CCD (10 ms drives), and if that is my SPARCstation 2, it
should deliver very fast performance on the 20 MHz SCSI bus.

I am patiently waiting for an install kernel that I can test.

What about netbooting a Risc PC from NetBSD/sparc or NetBSD/i386?
Is that possible, and if yes, how?

I'm getting quite a lot of ports around here in my 40 m=B2 flat, as I now
have:
- Acorn Archimedes A310
- Acorn R140
- Acorn Risc PC with SA-110
- SPARCstation 2
- 486DX/33
- HP 9000/712
- My portable work pc, a Dell Latitude LS-400

Not all of them are running NetBSD at the moment, but I expect to have
them up and running NetBSD in the months to come if possible.

Whenever Mike has an install kernel ready for me I can proceed with the
testing on NetBSD/arm32

Thanks for your help so far!
