Resource Configuration
4.2.1
PCI Auto Configuration
The BIOS automatically configures PCI devices. Currently on the CRB there is a 32/33
PCI add-in card socket. Auto configuration lets a user insert or remove PCI cards
without having to manually configure the system. When a user turns on the system
after adding a PCI 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 add-in card.

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
Non-Plug and play operating systems, such as Microsoft Windows NT*, 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 can obtain
the SMBIOS information.
4.4
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 is used to access the BIOS Setup
program, and to install an operating system that supports USB.
