Yes, first I had the QD21 in slot 4, and then realized if I
didn't have any memory boards in slot 2 or 3, I needed to
move the QD21 up to the A-B connectors on slot 2. I was
then surprised to get the same result.
This is in a DEC H9278-A backplane that originally had an
LSI-11 in it. I don't know if I need to do anything to the
backplane to make it work for a uVAX-II.
Thanks,

I am trying to get an Emulex QD21 configured on a
MicroVAX-II...
So, somehow the QD21 is not copying the diagnostic program
to the VAX memory.
I would ensure your NPR Grant Chain above the QD21 is intact.
That
would be the most likely reason it can't DMA the program into the
MIcroVAX.
