I have been trying to get my 2100 working. I have been 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:
Ultrixload - V4.5 Thu Sep 14 07:07:53 EDT 1995
Excptn: (vtr=NRML)
Excptn pc: 0x807001f8
Creg: 0x30000010(CE=3,EXC=RADE)
Sreg: 0x30000000(CU1,CU0,IPL=8)
Vaddr: 0xaaaaaafe
Sp: 0xa13fbba8
0xa13fbba8 : 0xaaaaaaaa 0x80701310 0xa0003b60 0x80700000
0xa13fbbb8 : 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa
0xa13fbbc8 : 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa
0xa13fbbd8 : 0xaaaaaaaa 0x80700048 0xa00039c8 0xaaaaaaaa
0xa13fbbe8 : 0xaaaaaaaa 0xaaaaaaaa 0xaaaaaaaa 0x00000000
0xa13fbbf8 : 0xaaaaaaaa 0xaaaaaaaa 0x00000001 0xa00039c8
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?

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

Oh, also, did you boot once, then interrupt, then try to boot again? I
honestly don't remember if it's like on the VAX but sometimes the machines
get confused and you need to INITIALIZE between boot attempts. Just another
idea. MOP boot just fails completely now across power cycles, etc?

Sorry for the delay in replying. I am not able to try the things you
suggest for a couple of weeks now. I didn't try MOP booting NetBSD, but I
certainly could try that. I tried booting the DECstation across power
cycles, but until I have done an initial boot off CD-ROM it won't MOP boot
at all.

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?
