Hi Robert,
Will it MOP boot NetBSD successfully? Something to help give you a feeling
if the issue is intrinsic to the machine or it's just something with Ultrix
4.5.
You can always try swapping network cable, switch port, AUI transceiver...
sometimes this stuff can have some unexpected effects... I had an old
SPARCstation 10 years ago that wouldn't boot from any media... or it was
just continuously locking up, crashing... I don't remember... but after
replacing every part in the box, finally swapping another SPARCstation 10
entirely and having the issue persist, I found it was, believe it or not, a
bad Ethernet cable!!
Best,
Sean

using MOP to boot
the
machine and try to install Ultrix, although this is not working for some
other reason at the moment. Until this morning, it was booting from MOP
just
fine, but now it, after leaving the machine overnight and not doing
anything
to it, I get this when I try to MOP boot:

exit(-1)
The really strange thing is that if I attach a CD-ROM drive and boot off
that first, then try the MOP boot after that, the MOP boot works! Before
anyone asks, I have other problems which mean it won't successfully install
Ultrix from the CD-ROM, and I am trying the MOP route because of this. The
CD-ROM problem is something to do with the block size, I know about the
block size jumper and have tried with the jumper installed and removed.
I have a workaround which is to connect the CD-ROM, boot off the CD-ROM,
let
the CD-ROM installation fail, then unplug power from the CD-ROM and boot
from MOP. But that is horrible, and wasn't necessary until this morning.
Any ideas?
Regards
Rob
