BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE
auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub.
The BIOS can be upgraded by following the instructions in Chapter 3.
PCI Auto Configuration
If you install a PCI add-in board in your computer, the PCI auto-configuration utility in the BIOS
automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that
add-in board. You do not need to run the BIOS Setup program after you install a PCI add-in
board.
IDE Auto Configuration
If you install an IDE device (such as a hard drive) in your computer, the IDE auto-configuration
utility in the BIOS automatically detects and configures the device for your computer. You do not
need to run the BIOS Setup program after installing an IDE device. 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
LAN Subsystem (Optional)
The optional Intel 82562ET (with the Intel 82801BA ICH2) provides a Fast PCI LAN subsystem
providing both 10Base-T and 100Base-TX connectivity. The Intel 82562ET provides the
following functions:
• Basic 10/100 Ethernet LAN connectivity
• Supports RJ-45 connector with status indicator LEDs
• Programmable transit threshold
• Configurable EEPROM that contains the MAC address
