OpenBSDInstallPrelude

At the moment, the only way to install OpenBSD/vax is via diskless 
booting over an Ethernet network.  You will need both the "boot.mop" 
image and the "bsd" kernel to boot.  You will also need a machine 
configured as a rarp, MOP, bootparam, and NFS server.  

This document will give a few examples on how to set up each of these 
services on an OpenBSD machine; if this is not enough information, 
check out the OpenBSD manpages for rarpd(8), mopd(8), rpc.bootparamd(8), 
bootparams(5), nfsd(8), mountd(8), and diskless(8).  Also, Brian Chase 
<bdc@world.std.com> has written a guide for booting a VAX off of a 
network; this was written for NetBSD/vax, but the procedure is virtually 
identical for OpenBSD/vax, and the document covers the use of several 
different platforms as servers.
The guide is available at:

Configuring the Server:
---------------------

When you turn on your VAX, it will run a set of self-diagnostic ROM routines.
Depending on the model of VAX you have, it may take quite a while.  When 
it is done, you will see a >>> prompt (also called the chevron prompt) on the
console.  Typing "show dev" or "show ethernet" to get the VAX ethernet 
device's MAC address usually works; also try "TEST 50" on MicroVAXen 2000
and 3100.

You will need to create an /etc/ethers file.  This file is used by rarpd to 
answer rarp (ethernet address->IP address) requests.  The format of this file 
is the ethernet address followed by the machine name or address.  Here is an 
example:

08:00:2b:24:72:00		quickvax

Then start rarpd (or configure /etc/rc.conf to always start rarpd).

Copy boot.mop into /tftpboot/mop/AABBCCDDEEFF.SYS, where "AABBCCDDEEFF"
represents the six octets of your ethernet address.  For example, the 
filename for the machine described above would be "08002b247200.SYS".
Start mopd by typing "mopd -a".

rpc.bootparamd's configuration file is /etc/bootparams.  The format for this
file is described in the diskless(8) and bootparams(5) manpages.  Enable
rpc.bootparamd in /etc/rc.conf by changing the value of "bootparamd_flags". 
Also, make sure "portmap" is "YES"; you will need portmap running.  

nfsd and mountd configuration are described in their respective manual pages.
Make a separate directory for your VAX's /, make sure it is exported via NFS, 
and place "miniroot.fs" there.

Typing "B <DEVICE>", where <DEVICE> is your VAX's ethernet device, at the 
chevron prompt should then load the OpenBSD booter.  A countdown should begin;
type any key on the console and type "boot miniroot.fs".
