Re: Making an ATI Radeon X1900 PCIe work on a G5/Quad (or can I?)

With older cards the driver doesn't require any information from the
ROM, but with newer cards (as of X1xxx) it relies on byte code in the
ROM (called ATOM BIOS) for low-level initialization and modesetting. I
suspect the Mac Edition of the card doesn't have an ATOM BIOS though;
ironically a 'standard' card might work better.
Maybe, but without open firmware, it means booting in blind mode at best.
You can try the radeonhd driver instead, which relies less on the ROM.
Indeed I should have tried. But no more luck, it seems. Interesting
results, thought:

It requires AtomBIOS, and I am not sure it is provided in the card rom.
Thank you anyway.
