Subject: Netbooting a 9000/330 from an i386/1.1A

I recently was lucky enough to acquire a 9000/330 with the nice
serial/thinnet/HIL/HPIB card.  What I'd like to do at this point, since I
don't have a drive, is netboot it from the other NetBSD box on my desk, my
i386 box.  

The i386 box is running more or less -current, usually lagged a couple of
days.  I've got a filesystem built on the i386 for the HP to boot to, have
correctly setup the /etc/bootparams, and have gotten rbootd to load the
Net bootblocks on the HP.  (The HP FS is the 1.1 binary dist out of the box,
with /etc modified for netbooting)

The following script, while kinda long, shows exactly what transpires over
the network, in case I am misunderstanding some component of this.

A friend of mine mentioned that the failure to get the file might be related
to a byte order difference between the HP and the i386 box.

My question was whether it might be something RPC that I don't have
correctly setup (basically an out of the box system that has been upgraded
from 1.0A to 1.1A one sup at a time), or whether it truly is a software
problem, and what I might aim to do to fix it.  From the tcpdump, it would
appear that the i386 host (traveler) doesn't know how to respond to the
HP's (lunchbox) request.  I appreciate any help anyone may have on this, and
look forward to running two ports of NetBSD.  :)

(And wouldn't mind at all if someone told me to RTFM, as long as they
pointed me to the right FM.  :)  )
