Introduction

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

Memory (SPI Flash) and can be updated using a disk-based program.

The SPI Flash

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 MQ96510A.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.
