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.

Hardware Management

The hardware management features of Intel Desktop Board DP55WB enable the board
to be compatible with the Wired for Management (WfM) specification. The board has
several hardware management features including the following:
• Fan speed monitoring and control
• Thermal and voltage monitoring
• Chassis intrusion detection

Hardware Monitoring and Fan Speed Control

The features of the hardware monitoring and fan speed control include:
• Monitoring of power supply voltages to detect levels above and below acceptable
values
®
• Intel Precision Cooling Technology fan speed control, delivering acoustically-
optimized thermal management
• A thermal sensor in the processor
• Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed
®
Intel Precision Cooling Technology
Intel Precision Cooling Technology automatically adjusts processor fan speed based on
the processor temperature and adjusts chassis fan speeds based on the internal
system temperature.
