Introduction

The boards use 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 PE94510M.86A.
When the BIOS Setup configuration jumper is set to configure mode and the computer
is powered-up, the BIOS compares the processor 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.

The maintenance menu is displayed only when the Desktop Board is in configure
mode. Section 2.3 on page 46 shows how to put the Desktop Board in configure mode.
