    Tonight I thought I'd upgrade the screen card in this mac with a more powerful ATI Rage Theater card I got out of a Quicksilver. The card has both vga and dvi connections. When I boot it with the dvi connection the screens shows the apple logo and then turns black until I press the power button on the mac again. Next odd thing is when I click the about this mac it shows it as a Power Mac G3, which this definitely is not. Is this a software problem, so far it seems to work fine except for the having to press the power twice to use my Cinema Display.

    Your screen shot shows that you have a PowerMac1,2, which is NOT an AGP model, but is the PCI G4 model, also called the Yikes!

    One difference is that the AGP model has an AGP slot, and the PCI has only PCI slots.
    The PCI has a removable Firewire card, and the AGP has a Firewire port built-in to the logic board
    An external difference: the PCI G4 audio ports on the back are placed horizontally.
    The AGP model audio ports are placed vertically.

    Apple was behind the eight ball when launch day for the G4 PCI rolled around. To get it to customers on time Apple basically modified a G3 system board to accept the G4 processor. The PCI is thus limited by the G3 bus.

    Apple fixed that when they rolled out the AGP.

    I have a Radeon 9200 software CD somewhere, it has drivers so maybe I can copy them for you and it'll all work.

    Which kind of connector has the card got? Perhaps you can post a picture of it.

    It has vga and dvi connectors. If you have drivers Gavin I'd really appreciate it. The card works but I have to press the power button to get the dvi connection to come back on after the apple logo boot up.
