Overview of BIOS Features
3.1
Introduction
The BIOS is stored in the SPI device on the PCH SPI bus. If SPI flash programming is
necessary, contact your Intel technical representative about the SPI programming
details.
The BIOS displays a message during POST identifying the type of BIOS and a revision
code. The BIOS Setup program can be used to view and change the BIOS settings for
the CRB. The BIOS Setup program is accessed by pressing the <F2> or <Delete> key
after the POST test and memory test begin and before the operating system begins to
boot.
3.1.1
PCI Auto-Configuration
The BIOS automatically configures PCI devices. Currently on the CRB, there are six
PCI Express add-in card connectors. Auto-configuration lets a user insert or remove
PCI Express cards without having to manually configure the system. When a user
turns on the system after adding an add-in card, the BIOS automatically configures
interrupts, the I/O space, and other system resources. Any interrupts set to
AVAILABLE in setup are considered to be available for use by the add-in card.
3.2
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 clock frequency.
•
Dynamic data, such as event detection and error logging.
3.3
Legacy USB Support
Legacy USB support enables USB devices to be used even when the operating
system's USB drivers are not yet available. Legacy USB support may be used to
access the BIOS Setup program and to install an operating system that supports USB.
