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 63. SATA 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. 20
