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 SATA 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 SATA 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 Express add-in card in your computer, the PCI Express autoconfiguration 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 Express add-in card.
