I've been digging through a bunch of my older hardware that's been in storage, and I decided to play around with some Matrox video cards. I have two Milleniums and one Millenium II that were both successfully flashed to Mac ROMs and previously used in a 9500 system. I wanted to see if any of these would work for a second monitor in G3/G4s, and started testing out the Millenium II.
I downloaded the installer from Matrox and put the card in a Sawtooth booting OS 9.1. System profiler sees it but it never gets initiallized as a video output. Should it work in this system, or is there a ceiling on motherboard compatibility?
