    ASCENTIA 950N DOES NOT RECOGNIZE AST PCMCIA TOKEN RING CARD

    PROBLEM

    The Ascentia 950N system may not recognize the AST PCMCIA Token Ring Card if
    the sound option is enabled.

    If the Sound option under the Audio Options menu is set to Enable, the system
    (Cardsoft's CARDINFO utility) does not recognize any PCMCIA Token Ring
    Adapters.  For example, when Cardinfo is run, it will say;

    Slot 0:
    Card Type Unavailable
    Manufacturer = "IBM"
    Product Name = "TOKEN RING"

    CAUSE

    There is a conflict in the sound option's default base memory address 220h
    with the AST PCMCIA Token Ring Card.

    SYSTEMS AFFECTED
    AST PART NUMBER AND DESCRIPTION

    501707-XXX      ASCENTIA 950N

    SOLUTION

    1. In CONFIG.SYS, change the exclude memory address statement
    from D400-D8FF to D000-DFFF.

    2. In system Setup, Sound Option, select a Base Address from the following:

    240h
    260h
    280h

    Save the settings and exit.  Reboot the system.

    Note:
    Default Base Address 220h should not be used to avoid the conflict with the
    sound.
