Installing and running other OS than RT11 and XXDP (with TU58 emu) or BSD (with Vtserver)

As I told in a previous message, I was success installing RT11 v5.3 in one
ESDI drive managed with one Dilog DQ696 (treated as a DU drive) in one PDP11
where I boot with one copy of this OS managed with TU58EM (TU58 emulator)
from one PC laptop.
I shall try in a while to install BSD2.11 with Vtserver, and to start XXDP
from TU58EM.
But I should like to ask to ask everybody insterested about this question:
Can I install other OS in the PDP11 using these pieces of software (Vtserver
and TU58em) ?
I was thinking in other versions of Unix previous to BSD2.11, or other OS as
RSTS, IAS, RSX or DSM.
By the way... Is this one (DSM-11) available in some form ? I know of one
copy from one member of this list which was available some years ago but
this is lost actually as far as I know.
Regards
Sergio

I have installed 2.11BSD via vtserver. Then I used the running
2.11BSD system to help install other operating systems, by generating
disk images with simh, transferring them to the PDP11 via ftp and
using "dd" to write them to real disks.

Mmm... Interesting technique. Some special parm to use DD to write the
diverse OS's ? And with SIMH ?
I was thinking in RSTS, for example.

RSTS was the first OS I did it with. No special parameters are
necessary on either end. The format simh uses for disk emulation is
just a raw expanse of bytes, no weird stuff anywhere. That makes
things very easy. Just use the correct disk type in simh to make the
image file the right size. Use "rauser" and set the size explicitly
if you're using an MSCP disk that's not a "standard" DEC size like an
RD54 or whatever, like for your ESDI controller.
I made a bootable XXDP RL02 pack using this trick just recently.
I transferred it to my 11/83 running 2.11BSD using FTP, cabled up an
RL02 drive, put in a pack, did the dd, shut down, then I could boot
that RL02 pack.

Aha, I see. I think that I shall begin with the installation of BSD 2.11.
The ESDI drive has 739 Mb of capacity... I guess if could be possible to
define more than one partition ar PC style...
I confess happily my ignorance, I'm a complete newbie (or nerd) in this
matter :-)
Another option could be to have a couple of drives... I suppose that I could
use two boards (the DQ696 and one RQDX3) in the PDP-11/23 PLUS... and I have
one MFM drive from one old PC ready to use.
This last question make think in something that I've read in some place or
file... Is it neccesary to start up with XXDP to format the MFM drives
connected to one RQDX3 ?
Thanks

2.11BSD supports disklabels for
partitioning, but there's no
"universal" scheme supported by all operating systems. You may need to
get creative in order to get more than one OS on a single physical
disk.

You can't just hook up any old MFM
drive to an RQDX3, unless you want
to calculate the parameters required to format it. It can be done, but
it's not exactly straight forward. The DQ696 may be more flexible in
that area, I don't know.

You will need to format the drive if it's not yet been
formatted on
for a RQDX3 or something compatible, e.g. a MicroVAX. There is a
stand-alone version of the XXDP formatting program for VTServer (I say
"stand-alone", you still need to use boot.dd to load it).
Cheers,

It is, FYI. (for ESDI drives, that is)

The Webster WQESD/4 supports this as well. It's quite handy, though
I prefer SCSI with removable disk trays.
