3.1 Introduction
The D810E2CA3 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, ACPI, PCI auto-configuration utility, and Windows 98-ready Plug
and Play.
This 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 CA81030A.86A.

3.2 BIOS Flash Memory Organization
The SST 49LF004A Firmware Hub (FWH) includes a 4 Mbit (512 KB) symmetrical flash memory
device. Internally, the device is grouped into eight 64-KB blocks that are individually erasable,
lockable, and unlockable.
