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, 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
DPP3510J
.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.
