Yes, that will work, thank you.   I'll add it to the Web page.

And here's an easier way of doing this with diskimage.gz, if a 32Mbyte
root fileystem is the right size. (24Mbyte might be better for very,
very small disks.)

1. Connect HDD-C  to Machien B and boot Ultrix off HDB-B.
2. uncompress diskimage.gz.

3. On Machine-B, do  dd if=diskimage.gz  of=/dev/rz?c
		(where rz?c is HDD-C.
4. Boot machine-B from  HDD-C.
   Edit the disklabel from diskimage.tar.gz on /dev/rz?c
   to suit your local setup.

5. Unpack the *.tar.gz pmax sets onto HDD-C.
    (the tar sets could be NFS-mounted or you could copy them onto
     HDD-A ahead of time, and then mount it read-only.)

This way is a couple of steps shorter, doesn't require an i386, and
doesn't require moving any disk drives.

I really shouuld rebuild diskimage.tar.gz with a statically-linked
tar, gzip/gunzip, uncompres, vi, and ftp.  That would make it easier
to set things up. Next is  to add all the install/upgrade  scripts...
