3 Overview of BIOS Features 3.1 Introduction The board uses a Intel Visual BIOS that is stored in the Serial Peripheral Interface Flash Memory (SPI Flash) and can be updated using a disk-based program. The SPI Flash contains the Visual BIOS Setup program, POST, the PCI auto-configuration utility, LAN EEPROM information, and Plug and Play support. The initial production BIOSs are identified as FYBYT10H.86A. The Visual BIOS Setup program can be used to view and change the BIOS settings for the computer, and to update the system BIOS. The BIOS Setup program is accessed by pressing the key after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. NOTE The maintenance menu is displayed only when the board is in configuration mode. Section 2.3 on page 40 shows how to put the board in configuration mode. 3.2 BIOS Flash Memory Organization The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 64 Mb (8192 KB) flash memory device. 3.3 System Management BIOS (SMBIOS) SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components. The MIF database defines the data and provides the method for accessing this information. The BIOS enables applications such as third-party management software to use SMBIOS. The BIOS stores and reports the following SMBIOS information: • BIOS data, such as the BIOS revision level • Fixed-system data, such as peripherals, serial numbers, and asset tags • Resource data, such as memory size, cache size, and processor speed • Dynamic data, such as event detection and error logging Non-Plug and Play operating systems require an additional interface for obtaining the SMBIOS information.

Overview of BIOS Features
3.1
Introduction
The board uses a Intel Visual BIOS that is stored in the Serial Peripheral Interface
Flash Memory (SPI Flash) and can be updated using a disk-based program.
The SPI
Flash contains the Visual BIOS Setup program, POST, the PCI auto-configuration
utility, LAN EEPROM information, and Plug and Play support.
The initial production
BIOSs are identified as FYBYT10H.86A.
The Visual BIOS Setup program can be used to view and change the BIOS settings for
the computer, and to update the system BIOS.
The BIOS Setup program is accessed
by pressing the <F2> key after the Power-On Self-Test (POST) memory test begins
and before the operating system boot begins.
NOTE
The maintenance menu is displayed only when the board is in configuration mode.
Section 2.3 on page 40 shows how to put the board in configuration mode.
3.2
BIOS Flash Memory Organization
The Serial Peripheral Interface Flash Memory (SPI Flash) includes a 64 Mb (8192 KB)
flash memory device.
3.3
System Management BIOS (SMBIOS)
SMBIOS is a Desktop Management Interface (DMI) compliant method for managing
computers in a managed network.
The main component of SMBIOS is the Management Information Format (MIF)
database, which contains information about the computing system and its
components.
Using SMBIOS, a system administrator can obtain the system types,
capabilities, operational status, and installation dates for system components.
The MIF
database defines the data and provides the method for accessing this information.
The
BIOS enables applications such as third-party management software to use SMBIOS.
The BIOS stores and reports the following SMBIOS information:
•
BIOS data, such as the BIOS revision level
•
Fixed-system data, such as peripherals, serial numbers, and asset tags
•
Resource data, such as memory size, cache size, and processor speed
•
Dynamic data, such as event detection and error logging
Non-Plug and Play operating systems require an additional interface for obtaining the
SMBIOS information.
The BIOS supports an SMBIOS table interface for such operating
