           SOUNBLASTER PRO II FAILURE WITH 386/25 AND /33 PROCESSOR CARDS

    PROBLEM:       Distortion of ".WAV"-type files occur in Windows 3.1 when
                   played through a Creative Labs Sounblaster Pro II card.  The
                   problem only occurs in a system where the processor is a
                   386/25 or 386/33.

    CAUSE:         The Sounblaster card stops issuing DMA requests and times out
                   during the playback of a .WAV file due to the excessive amount
                   of time that the processor card takes to process the DMA
                   request.

    AFFECTED
    SYSTEMS:       All AST systems with a 386/25 or a 386/33 processor card with
                   AST part number 202403-00X.

    SOLUTION:      The 386 processor card must be replaced with a processor that
                   is not of the same type (part number).
