                        BRAVO 486/33 AND PIXEL WORKS RA-1280

    PROBLEM:       When using the AST Bravo II 486/33 with the Pixel Works RA-
                   1280 graphics board installed, the diagnostic software bundled
                   with the RA-1280 may hang when running board tests, requiring
                   a cold boot to restart the system.

    CAUSE:         The RA-1280 is a bus-mastering card that is not compatible
                   with the Premium II, Premium CLEM, and Bravo II 486 series of
                   computers.

    AFFECTED
    SYSTEMS:       AST Premium II systems.
                   AST Premium CLEM systems.
                   AST Bravo II 486 systems.

    SOLUTION:      AST Sustaining Engineering has determined that this problem
                   will not be fixed.  AST suggests using an alternate graphics
                   adapter.
