My Power Mac G4 seems now to be only capable in booting OS X DVDs, and none other. I have tried 6 different CD/DVDs other than my OS X installs and none work. I only ever get to a blank white screen on all of my install disks, which it surely isn't possible to be coincidence that all 6 are broken, so that is why I burnt and tried another. Just to point out, the installs I have tried are all Linux, and all different versions/distros. I have tried the three latest versions of Ubuntu, two latest Kubuntu and Fedora 11 Alpha release. Yes I have also checked that they are the PPC version of the distro. This is really starting to bug me, as I really want to install a Linux distro on my spare HD. Any help appreciated!
