Desktop Board Features Legacy I/O The board's Legacy I/O Controller provides the following legacy features: • One serial port header • One parallel port header with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP) support • Serial IRQ interface compatible with serialized IRQ support for PCI Conventional bus systems • PS/2-style keyboard/mouse interface • Intelligent power management, including a programmable wake-up event interface • PCI Conventional bus power management support The BIOS Setup program provides configuration options for the Legacy I/O controller. BIOS The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the PCI Express and SATA auto-configuration utilities. The BIOS is stored in the Serial Peripheral Interface (SPI) Flash device. The BIOS can be updated by following the instructions in Chapter 3 starting on page 59. Serial ATA Auto Configuration If you install a Serial ATA device (such as a hard drive) in your computer, the autoconfiguration 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 a Serial ATA device. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. PCI*/PCI Express Auto Configuration If you install a PCI or PCI Express add-in card in your computer, the PCI/PCI Express auto-configuration utility in the BIOS automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that add-in card.

Legacy I/O
The board’s Legacy I/O Controller provides the following legacy features:
•
One serial port header
•
One parallel port header with Extended Capabilities Port (ECP) and Enhanced
Parallel Port (EPP) support
•
Serial IRQ interface compatible with serialized IRQ support for PCI Conventional
bus systems

BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the
PCI Express and SATA auto-configuration utilities.
The BIOS is stored in the Serial
Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions in Chapter 3 starting on
page 59.
Serial ATA Auto Configuration
If you install a Serial ATA device (such as a hard drive) in your computer, the 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 a
Serial ATA device.
You can override the auto-configuration options by specifying
manual configuration in the BIOS Setup program.
PCI*/PCI Express Auto Configuration
If you install a PCI or PCI Express add-in card in your computer, the PCI/PCI Express
auto-configuration utility in the BIOS automatically detects and configures the
resources (IRQs, DMA channels, and I/O space) for that add-in card.
You do not need
to run the BIOS Setup program after you install a PCI or PCI Express add-in card.
