<p><a href="http://www.netbsd.org/ports/pmppc/">NetBSD/pmppc</a> can
run in GXemul on an emulated Artesyn PM/PPC board. Currently, no SCSI or other
disk controller is emulated for this machine type, but it is possible to run
NetBSD with root-on-nfs.
<p><br>
<a name="netbsdpmppc"></a>
<h3>NetBSD/pmppc:</h3>
<p>
<a href="20070616-netbsd-pmppc-diskless.png"><img src="20070616-netbsd-pmppc-diskless_small.png"></a>
<p>These setup steps will let you run NetBSD/pmppc with root-on-nfs:
<p>
<ol>
<li>First of all, the "<tt>nfs server</tt>" machine must be set up.
This needs to have a 750 MB <tt>/tftpboot</tt> partition.
<a href="#netbsdpmaxinstall">Install NetBSD/pmax 3.1 from CDROM</a>.
(Don't forget to add the extra partition!)
<p>
<li>Configure the nfs server machine to act as an nfs server.
Start up the emulated DECstation:<pre>
<b>gxemul -e 3max -d nbsd_pmax.img</b>
</pre>and enter the following commands as <tt>root</tt>
inside the emulator:
<p><table border="0"><tr><td><tt> </tt></td><td><pre>
<b>echo hostname=server >> /etc/rc.conf
echo ifconfig_le0=\"inet 10.0.0.2\" >> /etc/rc.conf
echo nameserver 10.0.0.254 >> /etc/resolv.conf
echo 10.0.0.254 > /etc/mygate
echo /tftpboot -maproot=root 10.0.0.1 > /etc/exports
echo rpcbind=YES >> /etc/rc.conf
echo nfs_server=YES >> /etc/rc.conf
echo mountd=YES >> /etc/rc.conf
echo bootparamd=YES >> /etc/rc.conf
printf "client root=10.0.0.2:/tftpboot \\\n swap=10.0.0.2:/tftpboot/swap\n" > /etc/bootparams
echo "bootps dgram udp wait root /usr/sbin/bootpd bootpd -d 4 -h 10.0.0.2" >> /etc/inetd.conf
cat >> /etc/bootptab
client:\
:ht=ether:\
:ha=102030000010:\
:sm=255.0.0.0:\
:lg=10.0.0.254:\
:ip=10.0.0.1:\
:rp=/tftpboot:
</b>(press CTRL-D)
<b>echo "10:20:30:00:00:10 client" > /etc/ethers
echo 10.0.0.1 client > /etc/hosts
reboot</b>
</pre></td></tr></table>
<p>
<li>Download the NetBSD/pmppc CD-ROM iso image, and the GENERIC kernel:<pre>
<a href="ftp://ftp.netbsd.org/pub/NetBSD/iso/3.1/pmppccd-3.1.iso">ftp://ftp.netbsd.org/pub/NetBSD/iso/3.1/pmppccd-3.1.iso</a>
<a href="ftp://ftp.NetBSD.org/pub/NetBSD/NetBSD-3.1/pmppc/binary/kernel/netbsd-PMPPC.gz">ftp://ftp.NetBSD.org/pub/NetBSD/NetBSD-3.1/pmppc/binary/kernel/netbsd-PMPPC.gz</a>
</pre>
<li>Start the DECstation emulation again:<pre>
<b>gxemul -e 3max -d nbsd_pmax.img -d pmppccd-3.1.iso</b>
</pre>and extract the files from the PM/PPC CD-ROM image to the
DECstation disk image:
<p><table border="0"><tr><td><tt> </tt></td><td><pre>
<b>cd /tftpboot; mount /dev/cd0a /mnt
for a in /mnt/*/binary/sets/[bcemt]*; do echo $a; tar zxfp $a; done
echo 10.0.0.2:/tftpboot / nfs rw 0 0 > /tftpboot/etc/fstab
echo rc_configured=YES >> /tftpboot/etc/rc.conf
echo 10.0.0.254 >> /tftpboot/etc/mygate
echo nameserver 10.0.0.254 >> /tftpboot/etc/resolv.conf
echo rc_configured=YES >> /tftpboot/etc/rc.conf
dd if=/dev/zero of=swap bs=1024 count=65536
cd /tftpboot/dev; sh MAKEDEV all
cd /; umount /mnt; halt</b>
</pre></td></tr></table>
<p>
<li>Create a configuration file called <tt>config_client</tt>:
<table border="0"><tr><td><tt> </tt></td><td><pre>
<font color="#2020cf">! Configuration file for running NetBSD/pmppc diskless with
! a NetBSD/pmax machine as the nfs server.</font>
<b>net(
add_remote("localhost:12444") </b>! the server<b>
local_port(12445) </b>! the client<b>
)
machine(
name("client machine")
serial_nr(1)
type("pmppc")
load("netbsd-PMPPC.gz")</b>
)
</b>
</pre></td></tr></table>
... and another configuration file for the server,
<tt>config_server</tt>:
<table border="0"><tr><td><tt> </tt></td><td><pre>
<b>net(
local_port(12444) </b>! the server<b>
add_remote("localhost:12445") </b>! the client<b>
)
machine(
name("nfs server")
serial_nr(2)
type("dec")
subtype("5000/200")
disk("nbsd_pmax.img")
)
</b>
</pre></td></tr></table>
</ol>
<p>It should now be possible to boot NetBSD/pmppc using the NetBSD/pmax
nfs server, using the following commands: (NOTE! Execute these two
commands in separate xterms!)<pre>
<b>gxemul @config_server</b>
<b>gxemul @config_client</b>
</pre>
<p>You might want to log in as <tt>root</tt> on the server machine, and
run <tt>tcpdump -lnvv</tt> or similar, to see that what the client machine
actually does on the network.
<p>When asked for "<tt>root device:</tt>" etc. on the client machine, enter
the following values:<pre>
root device: <b>tlp0</b>
dump device: <b>(leave blank)</b>
file system (default generic): <b>(leave blank)</b>
..
init path (default /sbin/init): <b>(leave blank)</b>
</pre>
