I mentioned this elsewhere, but thought I'd give it a mention here. I have a flashed PCI FX5200 that I've used in several G4 towers. This particular card is a PNY brand with 256mb of VRAM and dual VGA. I recently acquired an Xserve G5, which only has PCI-X slots so the graphics cards options are limited to PCI. Since high-performance PCI video cards are not exactly common, I'd intended to install the FX5200 long enough to get the computer set up(I ultimately plan to run it headless, but am not good enough in terminal to do everything through SSH). The computer is running OS X Tiger Server. When I attempt to boot the computer with the 5200 installed, it will boot to the gray Apple screen and show the spinning progress bar. It would, however, kernel panic before booting to the desktop. I was able to get it to boot to single user mode(I didn't try verbose mode). I installed a Rage 128, and it works perfectly although obviously is not a great card for Tiger. Does anyone have any ideas about what would cause the problem I was having? If it's of any relevance, when received the computer was running 10.4.0(the version it shipped with). I've since run software update and brought it up to 10.4.11, although I can't see this necessarily making a difference.
