+### How I installed Debian on a Sun Ultra 10 from the network
+
+First of all, the first thing I tried is to replace the long-dead CD-ROM
+drive with a newer IDE DVD-RW and install the latest OpenBSD release.
+This worked as expected. I need, however, to also run Linux on an
+UltraSPARC processor for development and the choice was Debian stable.
+The bootable CD installer from Debian always hangs at a seemingly random
+phase of the package installation process. The system has 256 MB of
+memory and a 10 GB Western Digital disk. After many tries, and not
+having identified the problem, I decided to try the network boot
+installer and see what happens. This also failed, but I will document
+the process of booting the installer from the network here.
+
+I connected back-to-back the Ultra 10 with my laptop that is running OpenBSD.
+The laptop will host the boot image on its TFTP server. Downloaded the
+`boot.img` for SPARC from the Debian website and put it into my
+TFTP server root:
+
+ # mkdir /srv
+ # cp boot.img /srv/
+ # echo 'tftpd_flags="/srv"' >> /etc/rc.conf.local
+ # /etc/rc.d/tftpd start
+
+Next found out the MAC address the Ultra 10 has (it is written on the
+top on the OpenBoot initial screen), and configured an IP address
+mapping for RevARP:
+
+ # echo 'de:ad:ba:be:de:ad snoopy' >> /etc/ethers
+ # echo '192.168.1.2 snoopy' >> /etc/hosts
+ # /etc/rc.d/rarpd start
+
+By default the machine will ask for a file named after the hex
+representation of its IP address:
+
+ # echo 192.168.1.2 | awk -F . \
+ '{ printf "%02X%02X%02X%02X\n", $1, $2, $3, $4 }'
+ # cd /srv
+ # ln -s boot.img C0A80102
+
+Now boot the Ultra 10 and press <kbd>Stop-A</kbd> to get to the `ok `
+prompt; here type `boot net`. I also used `tcpdump` on my wired
+interface to monitor all requests this whole time, and kept PF disabled
+while offline. When the installer loaded, I plugged "the other" network
+cable to do DHCP business as usual.
+
+
+### Installing OpenBSD on a Sun Blade 100 using network boot
+
+Edit the following configuration files to enable RevARP, BOOTP, and NFS
+services on the server.
+
+/etc/rc.conf.local:
+
+ tftpd_flags="/srv"
+ rarpd_flags=
+ bootparamd_flags=
+ portmap_flags=
+ mountd_flags=
+ nfsd_flags="-tun 4"
+
+/etc/ethers:
+
+ de:ad:ba:be:be:ef blade
+
+/etc/hosts:
+
+ 192.168.1.3 blade
+
+/etc/bootparams:
+
+ blade root=192.168.1.1:/export
+
+/etc/exports:
+
+ /export -alldirs -ro -network 192.168.1 -mask 255.255.255.0
+
+
+Get the bootloader and ramdisk files. Again, create a symlink named
+after the hex representation of the IP address `192.168.1.3`.
+
+ # mkdir /srv
+ # cd /srv
+ # ftp $MIRROR/OpenBSD/5.4/sparc64/ofwboot.net
+ # ln -s ofwboot.net C0A80103
+ # cd /export
+ # ftp $MIRROR/OpenBSD/5.4/sparc64/bsd.rd
+
+
+Connect the machines back-to-back and configure the network.
+
+ # ifconfig em0 inet 192.168.1.1
+ # /etc/rc.d/tftpd start
+ # /etc/rc.d/rarpd start
+ # /etc/rc.d/bootparamd start
+ # /etc/rc.d/portmap start
+ # /etc/rc.d/mountd start
+ # /etc/rc.d/nfsd start
+
+Boot the client machine and on the `ok ` prompt write `boot net bsd.rd`.
+To get to the `ok ` prompt press <kbd>Stop-A</kbd>. If you do not have a Sun
+keyboard press the power button two times while booting OpenBoot.
+
+Get cracking!
