                         VGA DRIVER SUPPORT FOR WINDOWS 3.1

    PROBLEM:       VGA drivers distributed with the AST systems do not support
                   Microsoft Windows 3.1.  The following two problems will occur
                   when attempting to load these drivers under Windows 3.1:

                   1) The Windows 3.1 logo will be overwritten with a 3.0 logo.

                   2) The 256 color drivers for both the 800x600 and 640x480
                      resolutions operate slowly and with considerable flicker.

                   The video drivers experiencing problems are contained on the
                   following diskettes:

                   DESCRIPTION                        PART NUMBER

              Premium II Integrated VGA drivers       910403-003/033
              Bravo Integrated VGA drivers            910524-031
              Advantage Integrated VGA drivers        910527-031

    CAUSE:         These drivers were written to support Windows 3.0 and were not
                   meant to support Windows 3.1.

    SOLUTION:      There is no solution for the above problems until drivers for
                   Windows 3.1 have been released.
