[SOLVED] PowerMac G5 unable to boot PPC ubuntu 7.10

[Chucklz15]

root@ubuntu:/# ls /dev/disk
by-id  by-label  by-path  by-uuid
root@ubuntu:/#

I'm going to have to finish this (I hope), a bit later. Going somewhere and will be back in about 4 hours.

Ok, I go soon to sleep (I live in Berlin...)
My two last suggestions (for today): run, from the chrooted Ubuntu

mkofboot -v

and post it here.
If it should work umount everything, as explained before, and restart.


Second option:
If you can't yet boot, try again from Open Firmware (comd+opt+o+f) with following (please, note the difference 0 and 1) :

boot /ht/pci@7/k2-sata-root/k2-sata@0/disk@0:2,\yaboot

or

boot /ht/pci@7/k2-sata-root/k2-sata@1/disk@0:2,\yaboot

or

/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@0/disk@0:2,\yaboot

or

/ht@0,f2000000/pci@7/k2-sata-root@c/k2-sata@1/disk@0:2,\yaboot

If you want to pursue the yabootconfig way:

/dev/disk/by-uuid numbers should point to device names like this (for this box)

admax@g4:~/forum$ ls -l /dev/disk/by-uuid/
total 0
lrwxrwxrwx 1 root root 10 2008-08-26 12:51 700bb606-55d1-4229-b211-556bd53b7079 -> ../../hda4

The by-uuid names should be links pointing to the sda partitions, but yabootconfig and ofpath are trying to interpret the uuid name (got from fstab) as device names which they need.

If there is some problem there, then an option is to give yabooconfig the bootstrap and root device name.

For example, (In your case -b /dev/sda2 -r /dev/sda3 I think)
I ran this as --noinstall for a test.

This would be done finally from the <chroot>/ with /proc /sys and /dev mounted as you have done.

 
admax@g4:~$ sudo yabootconfig -b /dev/hda2 -r /dev/hda6 --noinstall --debug

Create simple /etc/yaboot.conf to boot Linux from /dev/hda6? [Yes] y

And thats it, just run that command with the --noinstall? Or should I try tiresia's 4 solutions first?

UPDATE - IMPORTANT!!!: I did the ls -l /dev/disk/by-uuid command and this is what I got (I noticed that it didn't do sda2!!!!):

ubuntu@ubuntu:~$ ls -l /dev/disk/by-uuid
total 0

Hi Chucklz,

please, before trying my suggestiongs, try what pxwpxw suggests (me too i think is right)
You must be in the chrooted ubuntu (with /dev, /proc and /sys mounted)

sudo yabootconfig -v -b /dev/sda2 -r /dev/sda3

Please, tell me what you get.
If it doesn't work try my other solutions

[Chucklz15]

BINGO, YES!!! Your second solution seemed to have worked and I think I know why. I was looking around inside my computer and I noticed where my hard disk was located. It was in slot B, meaning slave, so in your second solution when you said "...sata@1..." it meant slave. Thanks everyone for your help.

[tiresia]

Right, I tought yesterday the same (because the patched ofpath gave a different path than that one you found days ago in the OpenFirmware - you have in fact seen the HD in slot A).
Now, from inside your new Ubuntu, you should anyway run (just to check that the command gives the same path that you used to boot)

 ofpath /dev/sda2

and install a correct Yaboot

sudo yabootconfig -b /dev/sda2 -r /dev/sda3 --debug

Please, if your g5 is now ok, mark the thread as solved

[Chucklz15]

How do I do that exactly?

UPDATE: Everything matchs what I booted with and the yabootconfig is working.
