I've been looking to install morphos on my powermac quicksilver but when I try booting the installer from any sort of media I get an error of some sort. When I try booting from a CD I get a white screen. When booting from USB I get the same thing, when booting from USB via openfirmware, I either get an error message or a white screen with a circle and cross in the middle. Am I doing anything wrong or would there be any alternative instructions?

Powermac g4 Quicksilver 2002 dual 1ghz, 1gb of RAM, ATI Radeon 9000 pro gpu with 64mb of vram
