This page describes installation procedure of Debian GNU/Linux (sarge) on Plathome's OpenBlockSS. The following procedure flushes the entire contens in the internal flash memory and the harddisk. Before proceeding, make a backup copy of all important files.
First, obtain the latest firmware for OpenBlocks from Plathome's support page:
http://www.plathome.co.jp/support/labo/obssr/At the time of this writing, the latest firmware is zImage.initrd.treeboot-20041101-1:
ftp://ftp.plathome.co.jp/pub/OpenBlockSS/zImage.initrd.treeboot-20041101-1Detailed procedure for upgrading OpenBlockSS's firmware can be found in the user's manual:
ftp://ftp.plathome.co.jp/pub/OpenBlockSS/pdf/userguide02.pdfAfter update, boot from the internal flash memory. The default password for root is root.
Create a partition for storing the customized Linux distribution on harddisk.
# fdisk /dev/hda
(create /dev/hda1 partition)
# mke2fs /dev/hda1It's better to use /dev/hda1 for installing the customized Linux distribution since the default kernel assumes /dev/hda1 for its boot device. The harddisk image of the customized Linux distribution can be found at
ftp://openlab.plathome.co.jp/pub/OpenBlockSS/hdimage-20041101-1.tar.gzInstallation of the customized Linux distribution is simple.
# ftp your-ftp-server
(fetch hdimage-YYYMMXX.tar.gz)
# mount /dev/hda1 /mnt
# cd /mnt
# tar xzpvf hdimage-YYYMMXX.tar.gzThen, reboot from the harddisk
# flashcfg c harddisk
# shutdown -r nowCrate partitions for the root filesystem and swap.
# fdisk /dev/hda
(create /dev/hda2 for root, and /dev/hda3 for swap)
# mke2fs /dev/hda2
# mkswap /dev/hda3
# mount /dev/hda2 /mntdebootstrap works fine for installing Deban GNU/Linux (sarge). But, it needs some tweaks since sarge is based on GLIBC 2.3 whereas the customized Linux distribution (hdimage-YYYMMXX.tar.gz) is based on GLIBC 2.2. The trick is using the latest version of debootstrap, but replacing /usr/lib/debootstrap/pkgdetails with an older one.
First, obtain the following two Debian archives.
ftp://ring.asahi-net.or.jp/pub/linux/debian/debian/pool/main/d/debootstrap/debootstrap_0.2.45-0.2_powerpc.deb
ftp://ring.asahi-net.or.jp/pub/linux/debian/debian/pool/main/d/debootstrap/debootstrap_0.1.17.7woody1_powerpc.deb
# mkdir /mnt/sarge-inst
# cd /mnt/sarge-inst
# ar x debootstrap_0.1.17.7woody1_powerpc.deb
# mv usr/lib/debootsrap/pkgdetails usr/lib/debootsrap/pkgdetails.old
# ar x debootstrap_0.2.45-0.2_powerpc.deb
# mv -f usr/lib/debootsrap/pkgdetails.old usr/lib/debootsrap/pkgdetails
# ln -s /mnt/sarge-inst/usr/lib/debootsrap /usr/libThen, invoke debootstrap:
# mkdir /mnt/sarge-root
# cd /mnt
# ./sarge-inst/usr/sbin/debootstrap sarge sarge-root http://ftp.jp.debian.org/debian/The required time depends on your Internet access link. If this fails, check your network settings (/etc/resolv.conf, /etc/sysconfig/network, /etc/sysconfig/network-scripts/ifcfg-eth0).
Use chroot for configuring your Debian GNU/Linux base system.
# chroot /mnt/sarge-root
# umount /proc
# mount -t proc
# base-configPerform minimal configuration for rebooting from Debian GNU/Linux. The following is a patch for my OpenBlockSS.

tts/0Before rebooting, getty configuration (/etc/iniittab and /etc/securetty) must be changed. Otherwise, you will not be able to login via serial console. I strongly recommend to install telnetd and ssh at this point for ensuring your login via network.
