I have an MTI QTS-30 (aka CMD CQD-200/Ts) and TTi QTS-1 / QTS-3 SCSI
tape controllers which I can use to boot a 2.11BSD install tape, but
the install process hangs up while trying to restore the files from
the tape to the hard drive. Anyone know for certain if the latest
patches might help that with these TMSCP controllers?
With the same SCSI tape drive and a CQD-220/TM I can complete the
2.11BSD tape install process to a hard drive attached to the
CQD-220/TM, but then it won't cold boot from the hard drive attached
to the CQD-220/TM. One of the MSCP boot loader patches is supposed to
fix that, but I haven't built and verified myself yet. It's on the to
do list.

Is it possible to install 2.11BSD from disk? Including a write-protected

Actually, that is the way I did it on my real 11/44 h/w. It has an MSCP
SCSI
(emulex UC17) disk controller that I have both a r/w hard drive (a 1GB
seagate)
and a scsi CDROM (a DEC RRD43 aka Toshiba XM4101B).
I did all the sysgen/config in SIMH, building 2.11BSD from tape and
installing
all the patches (and rearranging all the objects withing the kernel
overlays to
get the MSCP and TMSCP device drivers to fit .. but that is a whole
other story).
When I was happy with what was running on SIMH, I used the RA92 disk
image to
write an ISO cdrom using CDRWIN (or there are other freeware programs as
well).
Then I took the CDROM out to the real 11/44 h/w, and booted the CDROM
via the
DU device boot prom. 2.11BSD will boot to single user on a read-only drive.
To get the bits from the CDROM to the hard drive required a bit of trickery,
since 2.11BSD stores the partition map on the drive. 'dd' won't work before
the drive has been formatted under 2.11BSD. I used XXDP (booted from my
trusty
TU58 serial emulator) to copy the first 32MB from the CDROM to the hard
drive
as an image transfer. This 32MB contained the complete root filesystem, so I
could now boot the hard drive 2.11BSD image. At this point I could then use
'dd' to copy all the bits from the CDROM to the hard drive.
One last gotcha is that the CDROM is only 700MB, whereas the RA72 .dsk image
is 1GB, so the last 400MB is truncated. This was allocated to the '/user'
filesystem (nothing in it) so I just used standard 2.11BSD commands to
reimage
the filesystem in that partition.
So the long answer to both your questions is yes.

Assuming you have SCSI for your PDP-11, the easiest way to install is to
build the system using simh and then dd the resulting disk image to a
SCSI drive attached to the system running the emulation. Move the disk
to the PDP-11 and away you go. Somehow that seems like cheating. I used
this method for my first installation and then made some 9-track tapes
so I could get the authentic experience. :-)

I have a CQD-220/M and it does boot. I don't recall a problem, but I
know there was a problem with the KFQSA when using the DU boot loader.
Can a CD-ROM drive be attached to the CQD-220/M? If so, what drive types
have been successful?
Is there a way to convert a CQD-220/T to a /M or /TM? What about a
Viking TMSCP SCSI controller (forget the model)? I got them cheap,
knowing that they didn't do disk and hoping there might be a conversion
method some day.

The standard distributions that I have seen are Patch Level: 431
Patch 432 includes:
(5) The MSCP bootblock could not boot disks attached to a TD Systems
Viking MSCP controller.
Patch 441 includes:
(3) The MSCP bootblock would not work with a CMD CQD220 adaptor due to
the bootblock relying on the (undocumented?) behaviour of DEC
adaptors.
I haven't yet verified myself that 441 fixes the boot failure I am
seeing with my CDQ-220. The same drive moved to a SQ706A boots fine.
Can a CD-ROM drive be attached to the CQD-220/M? If
so, what drive types
have been successful?
I can boot an XXDP image burned onto a CD and the OVMS73 install CD
using a Plextor CD-ROM drive in 512-byte block mode on both a CMD
CQD-220/TM and a Dilog SQ706A, on a PDP-11 and VAX, respectively.
With the CQD-220 VMS identifies the CD-ROM drive as an RRD40, but with
the SQ706A VMS does not identify the CD-ROM drive as a CD-ROM drive
and I couldn't figure out how to mount the CD to finish the install
after booting and doing the initial standalone backup restore to disk.
Maybe some magic mount parameter is needed that isn't necessary when
VMS identifies the device as a CD-ROM drive.
Is there a way to convert a CQD-220/T to a /M or /TM?

I think this is a common wishlist item. I think if it is possible you
need to change both the firmware EPROMs and the PAL. Cloning EPROMs
from a /TM to a /T or /M would be trivial. If the PAL
is secured that
might be an obstacle. Has anyone sucessfully done this? Is there
a
/TM version of the CQD-200? I have CQD-200/T that would of course be
nice if it were a /TM.

I've no idea on the CMD, but for the Viking it is
more than just the EPROM
and PAL.
Are you sure? I thought the only difference was those two ICs, but if
you know more, I'd be interested to know what else is different.

One additional bit of info I can give you on the Viking boards is that you
want as new of firmware as possible in the EPROM if you want to use a
CD-ROM drive. Not all 512-byte CD-ROM drives will work. I've seen drives
that will work on a DEC Alpha not work on it. However, I've had good luck
with Plextor Caddy drives (6x and 8x). I think the other drive I got to
work was an RRD-42 (DEC Caddy drive).
