I have tried every PPC live CD I can get my hands on - Ubuntu, Lubuntu, Desktop, Minimal 10,12.04,12.10 yadda yadda.
Same result every time - boots to prompt. Type any flavor of startup (with and without splash, all variations). Boot process starts - gets to mounting the RAM disk (white screen with black letters) then flashes to a black screen with a Kernel Panic Message: Unable to mount root fs on unknown-block(0,1)
Can't find any suggestions that don't start with "boot off the live CD" which is the exact thing I can't do...
