3.1 Introduction

The Desktop Boards D845GEBV2 and D845GERG2 use an Intel/AMI BIOS that is stored in the
Firmware Hub (FWH) and can be updated using 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 RG84510A.86A.

When the Desktop Board’s jumper is set to configuration 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.
