Mel Assuming the DP G4 can boot OS 9, and the hard drive has OS 9 drivers installed, just boot off the OS 9 install CD and install it (just don't format the drive first, unless you want to blow away 10.3.8...) If it can"t boot OS 9, obviously stop here. It can't be done. If your drive doesn't have OS 9 drivers installed (sorry, don't know how to check, it is an option when you format the drive!), then you have to reformat your drive and select that option in disk utility.
