Installing Gentoo On Cobalt RaQ XTR

Posted in AtWherever by Rami on the February 20th, 2005

Requirments:

RaQ XTR
A Linux server having nfs supprt and running dhcpd

Download the following files:

http://prdownloads.sourceforge.net/cobalt-rom/cobalt-2.10.3-ext3-1M.rom?download
http://prdownloads.sourceforge.net/cobalt-rom/romutils-1.0.tar.bz2?download
ftp://ftp.cobalt.sun.com/pub/iso/960-RAQXTR01AU.iso.gz
ftp://ftp.cobalt.sun.com/pub/products/raq550/RPMS/kernel-2.4.16C12_V-1.i386.rpm

Copy the cobalt-rom as well as the romutils to the cobalt and run the following on the cobalt to upgrade the rom:

flashtool -v -w cobalt-2.10.3-1M.rom

If the upgrade fails keep on trying till it succeeds.

After a successful rom upgrade do the following on the linux server:

gunzip 960-RAQXTR01AU.iso.gz

mkdir /mnt/raq

mount -o loop 960-RAQXTR01AU.iso /mnt/raq

cd /mnt/raq

cp -a nfsroot-x86 /

Edit /etc/exports and add the following on the linux server:

/nfsroot-x86 192.168.1.0/255.255.255.0(rw,no_root_squash)

Edit the dhcpd.conf file and add the following on the linux server:

ddns-update-style none;
server-name "192.168.1.25";
next-server 192.168.1.25;
option root-path "192.168.1.25:/nfsroot-x86";
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.50 192.168.1.100;
}

Download stage1 from a gentoo mirror and place it in /nfsroot-x86 as well as the previously downloaded raq kernel.
Edit /nfsroot-x86/etc/rc.d/rc.sysinit and add /bin/bash before /test/main_script
Change the ip of the linux server to 192.168.1.25 and restart both the dhcpd and nfs.
Connect a serial console to the RaQ with 115200 8N1
Reboot the RaQ while holding the S key.
When it asks you for the device to boot select ‘boot from net’
When it’s done booting you will get a bash prompt at the serial console.
Proceed installing Gentoo as normal.
When done run the following commands:

emerge rpm
emerge xinetd
netkit-telnetd
rc-update add xinetd default

Edit /etc/xinetd.conf and remove the line that says "only_from = localhost"

Edit /etc/xinetd.d/telnetd and remove the line that says "disable = yes"

Edit /etc/inittab and remove all the lines having agetty then add the following line:

TO:2345:respawn:/sbin/agetty 115200 ttyS0 vt100

Run the following command to allow root to login from the serial console:

echo ttyS0 >> /etc/securetty

Edit /sbin/rc (remember to do that everytime /sbin/rc is updated) and change any devfs="yes" to devfs="no"

Copy the earlier downloaded kernel to / of the gentoo system and run the following:

rpm2cpio kernel-2.4.16C12_V-1.i386.rpm | cpio -i –make-directories

Reboot

Press the spacebar when prompted to enter the ROM mode

Enter the following commands:

boot
set_boot_type disk
set_root_dev hde3
set_boot_dev hde1
reboot

Enjoy
