After 2 months of good regular working of an ATI X800 XT Mac Edition video board on my dual 1.8 G5 PowerMac, my Mac began starting up in Open Firmware mode; moreover, waking up from stop mode it suddenly shuts down. Exiting or booting from open firmware makes the Mac working absolutely normally.
Why that??
Apple official support laboratory made several trials including new buffer battery, but no way. At least they took off the X800 XT and changed to native GE FORCE FX 5000, and all turned perfectly well. But they could not give me a reasonable explanation, and i still do need that faster graphic card. I flashed the ATI ROM to the last available upgrade, but no changes. Can anyone solve my problem?
ATI website support was not useful. Note that the ATI card is true native Mac Edition, never been modded.
