Thank God, I'm not the only one ;-)

I was having problems just as you described.  With much help from Ted
Lemon (specifically, his port of NetBSD disklabel to Ultrix) I was
able to get going.

If you have Ultrix, I'd suggest grabbing disklabel from
~ftp/pub/NetBSD/arch/pmax/tools on ftp.netbsd.org.  Write and install  a
label that puts a at an offset >= 16.  Place your bootblocks (rzboot &
bootrz) in the ultrix /usr/mdec (this is safe, as Ultrix uses one
file, bookblks, for its boot blocks), and install them using the -B
arg to disklabel.

Then dd the miniroot to wherever you started a on the NetBSD disk. If
you started a at 16, then you'd say 'dd if=miniroot of=/dev/rrz#c skip=16'

For some odd reason, I couldn't get the latest miniroot of Jonathan's
to work - the kernel loaded & then the machine hung (3100, KN01
V7.03).  But I managed to get off the ground using the 2-14 version.  

If you need more help, feel free to send me mail -- I just went
through all this in the last 48 hours.
