    I tried the Radeon X800GTO AGP card and can confirm :

    It does not work ! (at least with my 2GHz G5 PowerPC)

    I do not get any picture !

    Did you have MorphOS installed previously (before the gfx card swap) or are you trying to boot an AGP G5 Power Mac from CD using AtomBIOS card? Because the latter won't work.

    EDIT: I just figured out X800 is not an AtomBIOS card, so you won't be able to boot anyway. You need a newer Radeon (or Apple BIOS for this card).

    But it is, just too old version of AtomBIOS for MorphOS (see comment #21).

    Back again :-)

    I bought a X1950 Pro Xtreme 512mb from ebay, dont know anything about AtomBIOS, but some suggested to leave the original card in the Mac.

    Should i put the new X1950Pro in Slot 3 which is a X8 slot ? slot 2+4 is only X4

    The Fan on the X1950Pro is huge and the Clear plastic side won't fit :-(
    so i need to find another Fan/cooling solotion for the X1950Pro.


    and last which PCIe Lan sould i look for ?


    Regards

    Peter

    You should always put the Radeon in "main" slot, so the x16 one is the way to go. If you want to leave nVidia inside - use some other one.

    You can get rid of the plastic deflector - the airflow should be fine enough without it.
    Just make sure to put a piece of paper inside the right bottom hole for the deflector (notice the deflector had a white sticker there), there's an optical sensor you need to fool. Otherwise the fans will blow at full speed when the machine realizes there's no deflector present.

    Take a look at this thread. You'll find a list of tested and compatible cards for your machine.

    Radeon X1950 cards with 512 MiB have been reported (#8) to work fine with MorphOS, just that only 256 MiB are recognized (which is expected).
