install NetBSD on pmax

I've attempted to install NetBSD on a decstation with
no success.

I've tried numerous permutations of the directions, but what
I think should have worked was:

I put the disk on a decstation 5000/120 running ULTRIX 4.3.
I compiled disklabel with gcc 2.5.8, moved bootrz and rzboot
to /usr/mdec and ran disklabel as such:

./disklabel -B /dev/rrz3c
  (some warning about no disk label)
./disklabel -B -R /dev/rrz3c rz24

Now, if I run ./disklabel -r /dev/rrz3c it looks good.  I then
did the dd:

dd if=./miniroot of=/dev/rrz3c seek=16

the disklabel is still in tact.  So, I didn't clobber it.

However, the resultant disk is NOT bootable on a decstation
5000/133 or a 2100.  Anyone get this beast to work?

A friend tried labeling the disk from a macintosh running NetBSD
but that didn't work either.  Both machines will boot ULTRIX and
I'm certain I have the boot rom environment variable set correctly.

Help!?

The install guide is wrong. The right command is:
dd if=./miniroot of=/dev/rrz3c seek=16 skip=16
(you can also do :dd if=./miniroot of=/dev/rrz3c before labelling the disk).
This is because the miniroot also contains the 8k for disklabel+boot blocks.

Yes.
