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.
