What you described here makes sense and was my first impression of
what should happen, but my experience is different.

My /etc/dtab is:

ra      ? 172150 154    5       raintr          # uda50, rqdx1/2/3
ra      ? 160334 160    5       raintr          # secondary mscp

The CQD220 is at 172150 and the RXDX3 is at 160334. Is 172154 a valid
MSCP address? It must be, cause it works for you. The docs I have
show 160334.

On booting the 11/73 and starting 2.11 BSD the following occurs:

DU8 and DU9 at boot are the RX50 drives on the second controller. The
floppy in DU8 contains the installation standalone utilities that were
part of the installation tape, including icheck.

I agree that it is pretty simple as you describe it and it is what I
expected,
but it does not seem to be as I see it here. Could the problem be that I
am
booting from the second controller? Should all the controllers be
jumpered for
unit 0? Now that I think about it, it may be the boot firmware that is
uncooperative. If I set the RQDX3 for unit 0, I cannot boot from the
second
controller's first disk, but I can from the second. So, I should set all
the
controller unit numbers to 0. The restriction is that the boot device
must
be visible to the firmware. Make sense?

...

OK, I moved the RQDX3 to unit 0, and the boot floppy to the second
drive.
The boot is then:

Thanks for helping me work through this. It looks like the boot device
must be
within the first 8 devices that the firmware can see, but 2.11 BSD wants
all
the unit number jumpers set to 0.
