Hello, I have recently purchased a used IBook G4 1.42 Ghz to replace an older G4 Ibook I owned. My intention was to take out the new IBook's current hard drive (OS 10.4.2) and replace it with the hard drive in my previous IBook (10.3.9). When I dropped it in and tried to boot I was met with a flashing ?/Apple Face folder logo. I would like to stick with 10.3.9 for a while until some of third party vendors catch up with 10.5. So my questions are: #1. Is it possible to run the last generation of IBook G4 (1.42) with OS 10.3.x? #2. If so, should I just erase the hard drive and do a clean restart, or am I doing something else incorrectly?
