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 the Serial
Peripheral Interface (SPI) Flash memory device.
The BIOS can be updated by following the instructions in Chapter 3 starting on
page 69.
SATA Auto Configuration
If you install a SATA device (such as a hard disk 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
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 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.
