                       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).

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

SOLUTION:       1. Turn the system on.  When prompted to go into System Setup,
                   press and hold <Ctrl>+<Alt>+<Esc>.
                   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.
