Any ideas will be appreciated.Well, the debian-installer works, provided that you upgrade yaboot tothe one from the unstable distribution. So if you do not have importantdata on your ubuntu, you could install a debian sarge instead. This is what I have at home and booting osX was not a problem. I have documented how I installed sarge on my mac on the following installation report. http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=340980 Also, if you are lucky, you might find a working yaboot.conf in the debian bugs or the list archives. Lastly, here is the debian installation manual, which might contain useful stuff related to your problem. http://www.debian.org/releases/stable/powerpc/index (By the way, I have no macintosh background, but I wonder wetherpressing the option after reset would start another boot selector whichis not yaboot...) Best, and good luck ! -- Charles
Thanks Charles. No, I didn't find anything that would work for me and my yaboot problem. I have also been looking at http://penguinppc.org/bootloaders/yaboot/doc/yaboot-howto.shtml/ ch9.en.shtml, but unfortunately nothing that I understand that could help. While installing a vanilla Debian system is tempting (I have even downloaded the netinstall iso), I have a working Ubuntu system and even though it is somewhat fiddly at this point, it is working and seems a waste throwing all that time and effort out of the window :-( Not to mention, that Ubuntu Dapper Flight 3 PPC is the first version of Linux that I have actually gotten to boot without crashing.
I honestly believe it is simply a configuration issue, so in the hope that someone else on the list picks up on this thread, I am including my yaboot.conf file content at the end o this mail.
