I've been trying but when it goes to device
detection it always turns
up with an empty list. I mean, the install kernel boots, detects the
virtual hard disk and the CD-ROM, the install program starts and reaches
the installation menu (options for BASIC or ADVANCED) and it's then,
when choosing any option that it does not detect any suitable install
I know that I figured out, a number of years back, how to install
Ultrix on non-supported media. It involved aborting the install,
editing the install script to "recognize" the target media, and then
restarting the script. You might want to experiment with this...
I've managed to do this by editing the ULTRIX install script,
'install.1', to support installing from RA disks. It turned out to be
I have media and licenses for ULTRIX and UWS V4.3 (My media is
AG-ND76E-RE, September 1992), so that's what I used for this experiment.
I don't know how ULTRIX 4.2, 4.4, or 4.5 would differ, you will have
to experiment. I just used dd to dump the CD-ROM image (i.e.,
"dd if=/dev/cdrom of=ultrix.iso bs=512")
I then set up SIMH with the following commands. You may be able to play
around with this and choose a different disk setup, but this is what
worked for me:
set cpu 64M
set rq0 ra90
set rq1 ra90
set rq2 cdrom
set rq3 disable
attach rq0 d0.dsk
attach rq1 d1.dsk
attach rq2 ultrix.iso
ULTRIX will see rq0 as /dev/ra0*, rq1 as /dev/ra1, etc. RA90 is
supported under ULTRIX 4.3, RA92 is not, and RA60 failed to work for me,
so my disk choices were limited. Your milage may vary.

You'll be greeted by the ULTRIX installer. It has a menu like:
Select one of the following options:
1) BASIC Installation
2) ADVANCED Installation
3) System management
Choose "3", which dumps you at a standalone shell, so you can edit the
installer script, 'install.1'
The only editor available in this environment is 'ed' (The Standard
Editor!). Invoke it with the command:
# ed install.1
If you have the same ULTRIX media I have, then you can just use these
If you have a different version of the installer, the line numbers might
be different, so you'll have to poke around in the file yourself.
Here's what to look for: Line 173 reads "BTD=`btd`". On SIMH, /bin/btd
returns an empty string, so we're just explicitly setting BTD to 'ra2',
the CDROM drive. Line 193 is part of a case statement that switches on
the value of $BTD, but there's no support for 'ra', so we'll just
the line that reads "rz *)" to "ra *)" instead. Voila! The script
should now work.
Type "w" to write out the file, "q" to quit. Then type ^D to exit the
shell and return to the installation script.
This time, choose "2) ADVANCED installation", and select the first RA90
device as the root disk. You should be able to install normally from
here on out.
