3.1 Introduction
The D815EGEW boards 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, the PCI auto-configuration utility, and Plug and Play support.
The D815EGEW 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 EW81520A.86A.
When the D815EGEW board's BIOS Setup configuration 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.
