Software Guide

PS/2 Mouse

The "PS/2 mouse function control" default setting is "Enabled".

If you do not wcint to use the on-board PS/2 mouse port or port con­

nector, disable this. When enabled, the port uses IRQ 12, whether or
not you connect anything to it.

Shadow Controls

The default setting for the "Video BIOS Shadow" is "Enabled".

This copies the video display card BIOS into system DRAM to im­
prove performance.

The next lines, "C8000-CBFFF Shadow" to "DCOOO-DFFFF

Shadow" are for shadowing other expansion card ROMs. The default
setting for these areas is "Disabled". If you have other expansion

cards with ROMs on them, you will need to know which addresses
the ROMs use to shadow them specifically. When you shadow a ROM
it reduces the memory available between 640KB and 1024KB by the
amount used for shadowing.

After you have made your selections in BIOS Features Setup,

press the <Esc> key to go back to the main screen. The next item is
Chipset Features Setup.
