Hi,
A problem was that having just a single UC07, I can't connect SCSI tape
and SCSI disk at the same time. I had no problems installing BSD from
SCSI tape to MFM disk. My MFM disk drive is non-DEC-geometry though, so
I'm using an Emulex QD01 MFM controller.
I was hoping that now I have BSD booting from the QD01, switching the UC07
to MSCP mode for disk instead of tape, I could then build a BSD SCSI disk.
But, BSD2.11 doesn't seem to see a second RA controller ("RA 1"), no matter
what I set the address on the UC07 to. I can boot BSD from MFM disk with the
UC07 in the system, but if the UC07 is set for MSCP disk mode, BSD isn't
seeing it. I'll dig into the kernel config to make sure I'm not overlooking
something obvious.
Thanks everyone for confirming that my MAP behavior is normal for MSCP devices,
and not some symptom of a problem. After a little more fiddling, I found
the UC07 behaves on the 11/73B and 11/83 if it's the only disk controller
in the system. I'm more having an issue trying to get two controllers
working at once, such that I can boot from my MFM disk or boot from SCSI
tape, and have another disk device to actually install to aside from the
QD01.
I have two other controllers, a CQD220A/E and a DILOG SCSI controller.
But, trying to get these to coexist with the UC07 isn't happening either.
With the CQD I can boot RSX11M from a SCSI disk that came with one of
the systems, but so long as the CQD is plugged into the system, booting
Heh. I'll have to try upgrading my 11/53 from 512 to 2MB that way. Did you
have to do anything else aside from adding the memory chips, and the
PROM and single resistor change associated with the PROM?

Huh?
I had almost no Problems to install 2.11BSD from a UC07 with tapes written
from simh (and my own convert program for writing tapes with the blocksizes
2.11BSD want to use) and that on a SCSI Drive connected to a 2nd UC07.
That are not real single UC07s, that are two on a single PCB, don't know if
that is to be called UC08 at all, but it worked fine. :-) So my 11/53 just arrived, and my 11/73 is on
it's way, both in BA23 chassis.
Inventory of the 11/53 is:
KDJ11-D/S CPU
Dataram 4093 with 2MB RAM
RQDX3 controller
I've made good progress on the 11/53, and successfully installed
BSD2.11 a MFM drive, by booting from an Emulex UC07 and DLT-8000
SCSI tape drive to perform the install. Ideally I'd like to get
the OS on a SCSI hard drive, but I'm having trouble getting BSD2.11
to recognize the UC07 as a second MSCP disk controller, which would
be the easiest way at this point. I'm not
having much luck with my 11/73, which turned out to
be an 11/83, for which I also now have a spare 11/83 and 11/73-B
CPU. In my 11/83 system, "MAP" shows the address the MSCP or TMSCP
address the UC07 is jumpered for, but nothing (blank line) under
"Device Type" for that address, no "DU" or "MU" description
like
from "MAP" on the 11/53. If I try to get into F.R.D. with @17772150/...,
it just spits out a question mark, as if nothing is at the address.
Maybe you have a problem with the DIP Switches on the Conteroller?
I have an 11/83 too (which was a 11/73 KDJ11-Bbefore, changed the DCJ11
and the xtal to 18Mhz Versions. No Problem with 2.11 BSD, it runs for
days w/o a single Problem. from UC07 connected DLT tape doesn't work
Likewise, if I plug in the DILOG controller with a 1GB SCSI disk attached,
the UC07 stops working. So maybe my real issue is getting two SCSI
controllers to work at the same time in the same box.
Although I can get the QD01 (MSCP) and UC07 (TMSCP mode) working at once
in the same machine, I'm not having any luck getting BSD to see the UC07
as a second MSCP disk controller, with the QD01 (DU0) primary one.
Right now my
CPUs are set to the "Initialize the Setup table" defaults.
- Several different CPUs behave the same way.
- I assume there might be a correlation between the problem with F.R.D.
and the fact the device isn't showing up like on the 11/53 in MAP,
but I don't really know since I've never seen it work right on an 11/83.
It works on a 11/53 wich was some DEC Server CPU before and which I've
polluted with the full amount of memory (1,5MB it was 512K before)
and it worked with my KDJ11-B with 15Mhz and 18Mhz and with and without PMI
RAM.
