3.1 Introduction

The Desktop Board D865PCD uses 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 RC86510A.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.
