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:
http://world.std.com/~bdc/projects/vaxen/VAX-netboot-HOWTO
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".
