BIOS

The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI
and SATA auto-configuration utilities, and the video BIOS.

PCI/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.
• If both the supervisor and user passwords are set, you must enter either the
supervisor password or the user password to access Setup. Setup options are then
available for viewing and changing depending on whether the supervisor or user
password was entered.
• Setting a user password restricts who can boot the computer. The password
prompt is displayed before the computer is booted. If only the supervisor
password is set, the computer boots without asking for a password. If both
passwords are set, you can enter either password to boot the computer.
For instructions on resetting the password, see Clearing Passwords on page 43.

Hardware Management Features

The board's hardware management features enable the board to be compatible with
the Wired for Management (WfM) specification. The board's hardware management
features include thermal and voltage monitoring.
The hardware monitoring and fan control subsystem is based on the Nuvoton
W83627DH-P legacy I/O controller, which supports the following:
• Processor and system ambient temperature monitoring
• System fan speed monitoring
• Power monitoring of +12 V, +5 V, +5 Vstdby, +3.3 V, and +VCCP
• SMBus interface
