Ok i have a G4 powerbook 400Mhz. When i try to boot from the cd it does nothing.(yes i know the cd is working)so i tryed to go into open firmware and boot cd. It gives me an error message "boot cd method <load> not found; ihandle=0 phandle=0 load-size=0 adler32=1 LOAD-SIZE is too small" I know the drive is not broken because it can boot the os 10.4 dvd just fine. i have tryed zapping the pram and the nvram and even the power mangement thing. If anyone has any ideas id be glad to hear. This is my first mac and i just got it today from a friend for free. It did have 9.1 on it then it had kubuntu linux now it has nothing but a half finished Fedora core linux install on it. Could the fact that the install for fedora only ended up going halfway have anything to do with it?
