BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, and the
PCI/PCI Express and SATA auto-configuration utilities.
The BIOS is stored in a Serial
Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions in Chapter 3 starting on
page 65.
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.
