1-14 Chapter 1: Product Overview
Board BIOS
The Processor board uses a Phoenix BIOS, which is stored in Flash
ROM and easily upgraded through the network connection or serial
port
.
The Flash EEPROM also contains the Setup utility, Power-On Self
Tests (POST), and APM 1.2
.
The board also supports system BIOS
shadowing, allowing the BIOS to execute from onboard write-
protected DRAM.
The BIOS displays a sign-on message during POST identifying the type
of BIOS and a five-digit revision code.
FLASH memory Implementation
The Intel 82801AB Firmware Hub (Flash ROM) is organized as a
512KBx8 device (4Mb total). It is divided into eight blocks, each of
64KB size. The physical ROM occupies FFF80000h through FFFFFFFFh
in high memory and the run-time BIOS occupies E4000h through
FFFFFh in lower memory.
BIOS Upgrades
Flash memory makes distributing BIOS upgrades easy
.
A new version
of the BIOS can be installed from the hard disk, network or through a
serial port.
The disk-based Flash upgrade utility, PHLASH.EXE, ensures the
upgrade BIOS extension matches the target system to prevent
accidentally installing a BIOS for a different type of system.
Setup Utility
The ROM-based Setup utility allows the system configuration to be
modified without opening the system for most basic changes
.
The
Setup utility is accessible only during the Power-On Self Test (POST)
by pressing the <F2> key after the POST memory test has begun and
before boot begins
.
A prompt may be enabled that informs users to
press the <F2> key to access Setup.
Note:
An external alphanumeric keyboard is not required to run the
BIOS CMOS Setup Utility, but is recommended for ease of use.
