                        PREMMIA LX ERROR WITH CORNERSTONE VIDEO CARD

    PROBLEM:        The Cornerstone Image Accel PC1608C/12 color 20/70 video card
                    is not recognized by the Premmia LX system when running OS/2
                    version 2.11.

    CAUSE:          The Premmia LX ROM BIOS is setup with the field Disable Shadow
                    Memory Size "Disabled".  This setting conflicts with the
                    Cornerstone Image Accel PC1608C/12 color 20/70 video cards' ROM
                    BIOS address.
