7800GS in a MDD G4
I have a dual 1.25GHz MDD G4 Mac (originally dual 1.0GHz) and a BFG GeForce 7800GS with the copper heatsink.
I flashed the card with the ROM from themacelite.com described as "GeForce 7800 GS generic (nvflash, gotoh), tmeperature sensor removed for G4 running Leo (gotoh) ²" successfully and taped over pins 3 and 11.
I have both OS 9.2.2 and 10.5.8 on my MDD, and have been trying to figure out how to get this card working. I modified NVDAResmanPPC.kext and NVDANV40HalPPC.kext and added my card's numbers (0x00f510de) and repaired the disk permissions both from inside of 10.5 AND from the 10.5 DVD, yet when I reboot with my card installed, I get 2 popups saying (System Extension cannot be used: blah blah blah, was installed improperly and cannot be used"
If I go to System Profiler, the card registers as a 7800GS, but Core Image is "software" and Quartz Extreme is "Not Supported".
If I run a game like Halo Demo, it doesn't open, giving me an error saying "An unrecoverable error has occured, and Halo Demo cannot continue.", which I assume means it found no OpenGL card.
What do I do? Any suggestions? I see japamac has a 7800GS in his QS, and has played with a Gainward Bliss 7800GS too. Help please? Thanks!
