Is this even possible? I'm trying to get Leopard on our G5 PowerMac, but it won't read the disk (it reads all other disks). Trying to figure out a workaround to get it installed, but I'm coming up empty. I was going to boot it to target disk mode and install from another computer, but we don't have any other PowerPC machines to use. I know the disk is good, because my other machine can read it fine. Any suggestions?
