Introduction

The following document outlines how one can make an OpenBSD net installation for a Sun Sparc Station 5/10/20.

The following instructions assume the following

Add the clients MAC address in /etc/ethers with a hostname eg. ss5.
```
echo "01:02:03:04:05:06 ss5" >> /etc/ethers
```
Add an entry in /etc/hosts for the hostname (eg ss5) with an IP address.
```
echo "10.0.0.2 ss5" >> /etc/hosts
```
Start rarpd(8).
```
rarpd -la
```
Copy boot.net from the OpenBSD/sparc release to /tftboot/ip-adress.SUN4M).
```
cp boot.net $(printf "%.2X" 10 0 0 2).SUN4M
```
Uncomment the tftp entry in /etc/inetd.conf and restart inetd.
```
kill -HUP $(cat /var/run/inetd.pid)
```

Create /etc/bootparams containing this:

ss5  root=10.0.0.1:/export/ss5/root swap=10.0.0.1:/export/ss5/swap

Start rpc.bootparamd(8).
```
rpc.bootparamd -s
```
Copy bsd.rd to /export/ss5/root/ and make bsd a symlink to it.
```
ln -s bsd.rd bsd
```

Edit /etc/exports and add entry for /export:

/export -alldirs -network 10.0.0 -mask 255.255.255.0

Create the swap file like this:

dd if=/dev/zero of=swap bs=1k count=16000
