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
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.

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed.
The security feature uses a mechanical switch on the chassis that can be connected to the chassis
intrusion header on the desktop board. See Figure 10 on page 37 for the location of the chassis
intrusion header.

Power Management Features

Power management is implemented at several levels, including:
•
Advanced Configuration and Power Interface (ACPI)
•
Hardware support:
 Power connectors
 Fan connectors
 Suspend to RAM (Instantly Available PC technology)
 Resume on Ring
 Wake from USB
 Wake from PS/2 keyboard/mouse

ACPI

ACPI gives the operating system direct control over the power management and Plug & Play
functions of a computer. The use of ACPI with the desktop board requires an operating system that
provides full ACPI support.

Power Connectors

The desktop board has two power connectors. See Figure 10 on page 37 for the location of the
power connectors.
