The second ways is by following the instructions at this web site:

http://penguinppc.org/bootloaders/yaboot/doc/yaboot-howto.shtml/ch9.en.shtml

under the title "9.2 Loading Yaboot". I strt my machine and hold the Command-Option-o-f keys and the open firmware screen appears at the prompt I enter:

0 > boot hd:2,yaboot

and yellowdog linux starts.

BUT I dont want to have to do this everytime to use linux, I had yaboot set up and now it is gone. Is there anything I can do to get yaboot running again so I can choose which OS to boot each time I start up?

Thanks for reading.

You should be able to straighten things out by simply running 'ybin' (as root) once you are booted into YDL. If your 'yaboot.conf' file is set up properly, this should reset the OF to recognize yaboot on the bootstrap partition first.

Hello!

I am faced with exactly the same problem. I therefore tried the above solution, i.e. I gave this OF commmand:

boot hd:12,yaboot

This started the loading of Linux, but it stopped a little later with this error message (copied by hand):

VFS Cannot open root device "hda15" or unknown-block(0,0)
Pleased append a correct "root=" boot option
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
Rebooting in 180 seconds.

That has a touch of "déjà vu", but one never knows what to do about it: it seems that I am supposed to write "root=/dev/hda15" or perhaps "root=hd:15" somewhere. As a matter of fact, it is already in yaboot.conf, and also in the kernel (default parameters), but this obviously is not sufficient. I have tried to add it to the OF command above, and at the prompts that come later, all to no avail.

Thanks to anybody that could point out the correct solution.

Charles
