3.1 Introduction

The board uses an Intel/AMI BIOS that is stored in the Firmware Hub (FWH) and can be updated

using a disk-based program.

The FWH contains the BIOS Setup program, POST, the PCI auto-

configuration utility, and Plug and Play support.

The BIOS displays a message during POST identifying the type of BIOS and a revision code.

The

initial production BIOSs are identified as WB91X10J.86A.

When the BIOS Setup configuration jumper is set to configure mode and the computer is powered-

up, the BIOS compares the CPU version and the microcode version in the BIOS and reports if the

two match.

The BIOS Setup program can be used to view and change the BIOS settings for the computer.

The

BIOS Setup program is accessed by pressing the <F2> key after the Power-On Self-Test (POST)

memory test begins and before the operating system boot begins.

The menu bar is shown below.
