initial install on pci express
I just purchased pc with an MSI K8N platinum motherboard and nvidia 6600 pci express card in it. When trying to boot from the Ubuntu 5.10 x86_64 cd, or install Centos 4.2 for x86_64, when the system starts the x server, the screen displays broad horizontal bands of broken color and a large square that follows the mouse, but is basically unusable. The people at the shop assure me that this is because "Linux doesn't support pci express". Is there something I need to pass as a kernel option, or do I have a defective card? The pc does not have windows on it, so I cannot test it that way.
any help would be greatly appreciated
