After wrestling about two days with yaboot, the kernel boots fine. Now I can recommend (on iBooks and alike): - make yaboot's partition of type Apple_Bootstrap (anything else didn't work for me) - 1MB is fine (800k is minimum (still true?)) - splitting the swap partition is a good choice if you have a running system - move it up/downwards to the second position (moving partitions is a nice feature) - if you want MacOS press option while booting - "video=ofonly" is a good last resort help Could someone please put the following explanations into the yaboot-faq: Option is the key with alt and a half-fork on it. Command is the key with the apple and the knotlike figure I had not been a Mac expert, so I had to guess. Christof ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
