3 Overview of BIOS Features

3.1 Introduction

The board uses an Intel BIOS stored in the Serial Peripheral Interface Flash Memory

(SPI Flash) that you can update using a disk-based program. The SPI Flash contains

the BIOS Setup program, POST, PCI auto-configuration utility, LAN EEPROM

information, 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

BPX5810J.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.

You can use the BIOS Setup program to view and change the BIOS settings for the

computer. You access the BIOS Setup program by pressing the <F2> key after the

Power-On Self-Test (POST) memory test begins but before the operating system boot

begins. The menu bar is shown:

Maintenance Main Advanced Security Power Boot Exit

NOTE

The maintenance menu displays only when the board is in Configure mode.

Section 2.3 shows how to put the board in Configure mode.
