Hello, one of my ibook's onboard RAM is defective (failed memtest's tests, though AHT said everything is ok, but I had issues). I have an extra stick of RAM in there, which is good. Now I am following a solution by KawaiiAurora and ask, if someone can write me such a file, or if this is even possible. The onboard RAM is 512MB big. It is an ibook G4 mid 2005 12". Thanks in advance!
