3.3 Resource Configuration

3.3.1 PCI Autoconfiguration

The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards.
Autoconfiguration lets a user insert or remove PCI cards without having to 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 the add-in card.

The versions of PCI and Plug and Play supported by the BIOS

3.3.2 PCI IDE Support

If you select Auto in the BIOS Setup program, the BIOS automatically sets up the two
PCI IDE connectors with independent I/O channel support. The IDE interface supports hard drives
up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape
drives, and Ultra DMA drives (see Section 1.4 for the supported version of ATAPI). The BIOS
determines the capabilities of each drive and configures them to optimize capacity and
performance. To take advantage of the high capacities typically available today, hard drives are
automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending
on the capability of the drive. You can override the auto-configuration options by specifying
manual configuration in the BIOS Setup program.
To use ATA-66/100 features the following items are required:
•
An ATA-66/100 peripheral device
•
An ATA-66/100 compatible cable
•
ATA-66/100 operating system device drivers
✏
NOTE
Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For
example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive.

3.4 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
