    This is an informational bulletin.

    The PCI IDE Card with TEKRAM DC-680/690 Controller not being seen in
    the Advantage! Adventure 80XX system.

    TEKRAM DC-680/690 controllers are marketed today on at least two PCI
    IDE Cards.  These controllers are hardcoded to use interrupt 14.
    AST's and other Plug and Play BIOSes claim interrupt 14 for the on-board
    IDE controller.
    The TEKMAR controller used in the AST Advantage! Adventure systems is
    not compatible with Plug and Play BIOSes.
