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.

The Desktop Boards’ compliance level with Plug and Play Section 1.3, page 16
