Trying to reinstall Panther onto a 1 Ghz iBook G4 currently running 10.3.9. It is an off-the shelf Panther disk as I can't find the disks that came with the machine. When I put the disk in, it reads fine, and I click the restart icon to reboot from the install disk. At this point, the standard apple logo comes up on the grey screen, then, after a few seconds, the apple logo shifts a handful of pixels to the right and gets a little screwed up visually. Then... nothing. It just sits in this position. Anyone have any ideas?
