                 PREMIUM/486-33TE AND WESTERN DIGITAL'S ELITE 16 COMBO

    PROBLEM:         Banyan Vines version 4.10 network software driver will not
                     initialize Western Digital's Elite 16 Combo network card, in
                     a Premium/486-33TE computer system.  The error that occurs
                     is "Controller Failure", and at this point the workstation
                     is unable to connect to the file server.

    SOLUTION:        This is not an issue that AST can resolve.  Currently,
                     Banyan Vines software version 4.10 does not support Western
                     Digital Elite 16 Combo card.  At this time Banyan Vines and
                     Western Digital are working together on a software driver
                     that will support Western Digital's Elite 16 combo card.

    WORKAROUND:      Banyan Vines and Western Digital Technical Support, both
                     agree that the NDS software driver should be selected when
                     installing the network card.  Also, the AST VGA Plus must be
                     forced to 8-bit mode.  If the AST VGA Plus is set for 16-bit
                     mode the system will not boot.  The reason for this error is
                     the software drivers that are supported in Banyan Vines
                     software are for the older Western Digital 8-bit network
                     cards.  The older software drivers are doing 8-bit writes.
