BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the
PCI/PCI Express auto-configuration utilities, and the video BIOS. The BIOS is stored in
a Serial Peripheral Interface (SPI) Flash device.
The BIOS can be updated by following the instructions on page 61 in Chapter 3.

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. You do not need to run the BIOS Setup program after installing a
Serial ATA device. You can override the auto-configuration options by specifying
manual configuration in the BIOS Setup program.

PCI and PCI Express* Auto Configuration

If you install a PCI/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/PCI Express add-in card.

Security Passwords

The BIOS includes security features that restrict whether the BIOS Setup program can
be accessed and who can boot the computer. A supervisor password and a user
password can be set for the BIOS Setup and for booting the computer, with the
following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup
options. If only the supervisor password is set, pressing <Enter> at the password
prompt of Setup gives the user restricted access to Setup.
