Under Ultrix, something like:
mount -r -o nodefperm,noversion -t cdfs /dev/rz4c /mnt
should work (for at least Ultrix 4.4 and later - dunno about 4.3A and
earlier).

It's a DECstation 5000/25 right? Try the following:
>> setenv boot "3/rz?/netbsd -a"
where the ? is your NetBSD disk's SCSI id.

A 1000 user licence? Probably make good money on comp.unix.ultrix with
it! I've only ever seen a 32 user licence here...

I've never done a CD install, but from the code it looks like you get a
chance to choose the device to mount the CD on. Is this is the case?
If so (as Jonathan says), use /dev/rz?a and not /dev/cd?a. Can you
please let me know if this works?

Yup. Maybe the sysinst fix is as simply as putting an initialiser in
arch/pmax/md.c ?
