I have a 12" Powerbook G4 that I recently purchased used. I restored it to its original OS of 10.2.8. I bought a tiger DVD from a user on Macnn and the DVD says: "Mac OS X Tiger Includes Xcode 2 CPU Drop In DVD" When I try to install it (reboot to dvd) it says I need to have 10.3 or later installed on the system to install Tiger. Do I really need to get 10.3 or is there a way for me to use this DVD? If so, I probably need to format the harddrive and install it on to a blank system. Please help me and I'd appreciate any input from the wise mac users!
