Hi folks,
Well, I've just board swapped the entire VAX into my MicroPDP cab and it
still gets the same error and stops at 3 with an error on the console of
'00000000 03'
Can anyone remember the uVAX I's boot sequence or remember what it's
supposed to do at that point? I've just had a nasty thought in that it might
be looking for the RQDX1 and/or RD52 and it's those that are dead. Can I use
the RQDX3 in there instead?
All *looks* fine with the CPU since it appears to pass its tests.
cheers!

You can use an RQDX3, but not with _that_ RD52 (since it's been LLFed for
an RQDX1). If you have an RD-drive that's been LLFed on a MicroVAX 2000
or a uVAX-II (w/RQDX3) with the field service diagnostics, _that_ will
work with your RQDX3 on your uVAX-I.
I save ST225s and ST251s from junked PCs for just that purpose. An ST251
won't be as reliable (or as fast) as your RD52 originally was, but they
are more plentiful. 40MB is plenty to hold MicroVMS. My running uVAX-I
has an RD51 on it (and uVMS 4.0 IIRC). It was the box we did final testing
on Qbus COMBOARDs - it's the OS and *maybe* as much as 1.0MB of our software.

Thanks Ethan, I should've phrased the question better 'cos it was the
compatibility with the UV I I was wondering about. If needs be I'll just
'borrow' the disk from one of my UV2000s :)

Aw, don't say that - I'll kick meself if it's just waiting for me to type
'b
dua0'! It's that long since I've seen an MVII get to the dead sergeant
prompt AND looked at the diag panel on the back!
I have to go and try that *now* :)

I thought that stopping at 03 just meant that it
wanted you to tell it the boot device manually.

*embarassed* :)
Well, sort of. If I type 'b' (single char commands only) it tries to boot
but gives up saying 'none of the bootable devices contain a program image'.
The activity LED on the RD52 (DUA0?) stays on and I can't get any signs of
life out of the RX50 (DUA1/DUA2?) so fingers are now pointing at the RQDX1
being uphappy, so tomorrow I'll take the drive out of my 'parts' UV2000
(that's what it says on the label!) and pair it up with the spare RQDX3 I
found in my cards storage. If that fails I'll dismantle the uPDP again and
use the RQDX3 out of that. Should have another RD54 floating round too.
cheers

I don't have any experience of the uVAX I, but the uVAX II
has no NVRAM and so it goes through a "sniffer boot"
where it looks for a bootable device in a particular
order. I expect that the uVAX I does something
similar.
I would exepct that you can type B DUA0 and it will
have a go (or complain that it doesn't understand you).
Some of the machines (like the VAX 8200) implemented
the console in microcode and so the commands were
extremely limited (as was the error reporting, which
you'll know if you ever used a VAX 8200!). However,
the uVAX II implemented the console in VAX macrocode
(i.e. ordinary VAX instructions) and I would have thought
the uVAX I would have done the same. Have a go
with B DUA0 (and then DUA1,2,3) and see if you
get any reaction whatsoever out of the disk or RX50.
Another approach might be to remove the uVAX I CPU and
memory and drop in a KA630 - or better yet a KA650/KA655.
That way you could poke around on the Qbus and see if
anything is visible, check for conflicts and try
to boot.
