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.
