Hi Isaac.

Try these notes (email re-use, I like it ;) :

The two files 'rzboot' and 'bootrz' need to be in the '/usr/mdec'
directory on the machine running 'disklabel'.

This won't interfere with the file already there, because Ultrix
uses a file with a different name, so this is "safe" :)

Note that some combinations of options seem to cause 'disklabel'
to fall over (segmentation fault). This is probably the options
that cause it to read the BSD label when there isn't one, IIRC...

I found it easiest to use the:

	disklabel -R -B /dev/rz?c <protofile>

form of the command, which almost always seems to work fine for
me, whether the drive has a BSD label on it or not.

Hope this helps.

There's a sample <protofile> in the Ultrix disklabel package,
edit to suit your drive parameters.
