A while back I tried this guide on my iBook G4 to try to get it to boot into OS 9, but it didn't work because the iBook was newer than the one in the guide. But my PowerMac G5 is from about the same time, maybe older. Would it be possible to install OS 9 on the G5 using this method? I'm going to try it out. Just think how fast OS 9 would be on a G5. If anyone knows that this would not work, please let me know. I'll get started soon. I appreciate any additional information that may help. Oh, there used to be a piece of software called CountDown G5 that would run OS 9 on the G5, but you can't get it any more.
