One can download the current installer snapshot from http://cdimage.ubuntu.com/non-ports/por ... owerpc.iso

To create a bootable install kernel one can use the following command in /install/powerpc directory of the CD:
Code:
mkvmlinuz -o /tmp/ubuntu -a chrp -z -k vmlinux -i initrd.gz
and then use the resulting file ubuntu to boot the system. For boot parameters take a hint from yaboot.conf in the same directory.

A similar command can be used to create a boot kernel during installation. Just before rebooting the machine one can change to another virtual console (alt+F3), hit 'enter', and a command line is there. Chroot to the freshly installed system, change to the /boot directory and use the command from above:
Code:
chroot /target /bin/bash
cd /boot
mkvmlinuz -o ubuntu -a chrp -z -k vmlinux -i initrd.gz
Ubuntu still uses the old ATA driver on Pegasos, so one can boot it using:
Code:
boot hd:X boot/ubuntu root=/dev/hdaY
where Y=X+1 :)

Stay tuned, I'm working to also get EFIKA running...

Well, it runs. But be warned: even just to login to XFCE needs ~50MB of swapping and a couple of minutes. More tomorrow...

Do you have the kernel source package or so for this version as shipped with Ubuntu? I'd like to look at the patchset they're using, I just don't have a system which is reliably extracting RPMs or DEB formats right now.

The SuSE 11.0 kernel patchset included a fix for pata_via which worked.. I'm trying to fix all this up for mainline and pushing to distros but it's a hell of a lot of work for 5 lines of changes..

Seems to me, that the pata_via fixes are now part of the Linus kernel. See http://kernel.org/pub/linux/kernel/v2.6 ... g-2.6.24.3

OpenSUSE factory still uses 2.6.24.1 and will be upgraded to 2.6.25 soon

OK. I took initrd from here: http://ports.ubuntu.com/dists/hardy/mai ... c/netboot/ and recompiled the Ubuntu kernel to include ethernet support for the EFIKA. I also filed a bug report on Ubuntu launchpad, so it will be part of the netboot image hopefully soon.

And a bad news (also for openSUSE): sound does not work.

If you are still interested, you can use the installer from here: http://genesi.hu/ubuntu/ubuntu33 The number '33' is derived from the above URL, as long as there isn't a newer netboot image, it should work. Sometimes it is two weeks, sometimes just two days :-)
