Need some help. Just purchased Tiger 10.4.8. Tried to install it on G4 Cube (450MHZ, 320MB ram, os 10.2.8). Get this error: Kernel Panic (....something about cpu 0....) Unable to find driver for this platform: "Powermac5,1" I can't go beyond this screen to install Tiger. I don't know what this is. What do I need to do? Thanks for your help.
