So I just got my hands on a Power Mac G4 "Sawtooth" (AGP Graphics). (20 GB / 640 MB / DVD ROM) It came with an ATI Rage 128 Pro graphics card installed, everything works fine. I completely wiped the hard drive, installed Tiger on the clean drive without OS 9 drivers. I've gone on to ATI's website and downloaded drivers for the card, yet when i stick the new card in, I still get no video to the monitor whatsoever. So, who here has upgraded the AGP card in an old G4? What weird quirky step am I missing?
