3.1 Introduction
The board uses an Intel
a disk-based program. The FWH 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 VG91510A.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.
