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).

AFFECTED: AST
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.
