                           PREMMIA GX P/90 ON-BOARD ETHERNET VERY SLOW

    PROBLEM:        When running NDIS drivers on a Banyan VINES 5.53 (6) network
                    in a Premmia GX P/90 system, the on-board ethernet is about
                    one tenth the expected speed.

    CAUSE:          Incompatibility between the default interrupt setting (IRQ 9)
                    and the interrupt setting for optimum network performance
                    (IRQ 5).

                    PART NUMBER            DESCRIPTION

                    501457-801      PREMMIA GX P/90 733M 16MB

    SOLUTION:       1. Turn the system on.  When prompted to go into System Setup,
                       press and hold ++.
                       Change the CMOS setting for the ethernet configuration from
                       interrupt 9 (default) to interrupt 5.
                       Save and exit.

                    2. Other cards using IRQ 5 will need to be changed to avoid a
                       conflict.
