Hello,

i have bought graphics cards for Quad G5 but neither works...

So i search one work on Quad G5 and MorphOS.

Thanks

Have a look over there:

Thanks amifrog for the link.

I know graphics cards compatible but i search one work on Apple Quad and MorphOS (tested).

I have bought 4 "compatible" cards but no success.

The card must be specific Apple or flashed for Apple...

It only needs to be Apple-flashed if you want to run Mac OS with it.

...or access OpenFirmware or the built-in boot menu. Another possibility is to use two graphics cards where one is just for MorphOS.

Thanks for clarification.
Here is the thread about it, btw.
