3 Overview of BIOS Features
3.1 Introduction
The board uses an 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 PYBSWCEL.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 50 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 systems. Using this
support, an SMBIOS service-level application running on a non-Plug and Play operating system
