The Question is:

 
When attempting a MOP boot my MicroVax 3600 I get the following:
 
...
-XQA (08-00-2B-0F-33-A8)
 
Device? [XQA0]:
 
(BOOT/R5:0 XQA0)
 
 
  2..
-XQA0
?4B CTRLERR, XQA0
?06 HLT INST
        PC = 00000C1A
Failure.
>>>
 
 
What can be causing this problem?  In a BA620 enclosure
Which slots are QB-CD and which are QB-QB?
Does the cpu have to be in the right most slot?
Which order should the cards be in from the cpu?
 
Please Help!!!
 
Sincerly,
Mr. David E. Kuder
 
 

The Answer is :

 
  The Q-bus configuration needs to be verified for correctness, checking
  for such problems as erroneously empty slots interrupting the DMA grant
  chain.
 
  The Wizard is unaware of a BA620 enclosure.  The typical enclosure used
  for the MicroVAX 3600 series is the BA213.  All slots in the BA213 are
  Q22/CD slots.
 
  Please see an existing discussion here in Ask The Wizard, "MicroVAX
  3500 Q-bus and bootstrap questions?"  (The MicroVAX 3500 uses the
  same basic parts and the same basic enclosure as the MicroVAX 3600.)
