3.1 Introduction
The D815EEA board uses an Intel/AMI BIOS, which is stored in flash memory and can be updated
using a disk-based program. In addition to the BIOS, the flash memory contains the BIOS Setup
program, POST, APM, the PCI auto-configuration utility, and Plug and Play support.
The D815EEA board supports system BIOS shadowing, allowing the BIOS to execute from 64-bit
onboard write-protected DRAM.
The BIOS displays a message during POST identifying the type of BIOS and a revision code. The
initial production BIOS is identified as EA81510A.86A.
When the D815EEA board 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.

The D815EEA board’s compliance level with APM and Plug and Play Section 1.3, page 16
