I have Mac OS X 10.3 on my G4. I wanted to do a fresh install with my dad's CDs that Apple sent him. They are upgrade CDs, so the installer will not let me install Panther (I am at version 10.3.1) Can I go into some preference somewhere and change something so that it reads my computer as 10.3.0 or something? I have heard you can do this. See, I have 2 HDs in this computer. The one I am using now is a 32GB IBM. My second drive is an 80GB IBM (much faster). I want to make the 80GB my primary drive, but I don't want to have one OS on each drive, I do not believe the computer will boot if I did that. The 80GB currently has nothing on it, its just chillin. So, any ideas?
