Note that none of the RQDXn have any BOOT ROMS,

I have a question about BOOT ROMS. Does a MSCP
compatible disk controller need a boot rom to boot
from a HD connected to it? I am ingorant about this
issue.
Yes, it does. For Q-Bus machines, the processor card (if it's a
quad-height, ie KDF11B or KDJ11B) should have boot ROMs that can handle
MSCP, though the older ones might not behave well with bigger/later
drives. The MXV11B-2 boot ROMs can do it, and they also fit the
MRV11D. DEC boot ROMs may not always work with third-party MSCP
controllers, but such 3P controllers often have their own boot ROMs.
You could enter an MSCP boot via ODT, but it's VERY long!
