3.1
Introduction
The BIOS is stored in the Serial Peripheral Interface (SPI) Flash device and can be
updated using a disk-based program.
The SPI 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 BX97520J.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.
