    Known Problems

    Some PCI machines will not start up if there is more than one Number Nine Imagine128 display adpter present. This is a BIOS limitation.

    The Revolution 3D cards used for driver development exhibited a slight distortion on screen under the following display modes:

    1600x1200x32@70Hz
    1280x1024x32@75Hz

    The distortion causes the right side of windows to undulate. This is most noticeable on a text filled window with white background. This seems to be caused by some unknown hardware problem on those cards.
