Intel Desktop Board DP43BF Product Guide 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 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 in the BIOS Setup Program" on page 54. Hardware Management Features The hardware management features of Intel Desktop Board DP43BF 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 Fan Speed, Thermal, and Voltage Monitoring and Control Features of the board's fan speed, thermal, and voltage monitoring and control subsystem include: • Monitoring of power supply voltages to detect levels above and below acceptable values. • Smart fan control provided by the legacy I/O controller, delivering acoustically- optimized thermal management. Fan speed controllers and sensors are integrated into the legacy I/O controller. • Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed according to thermal conditions. • Two thermal sensors (processor and a remote thermal sensor). 22

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 in the BIOS Setup
Program” on page 54.
Hardware Management Features
The hardware management features of Intel Desktop Board DP43BF 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
Fan Speed, Thermal, and Voltage Monitoring and
Control
Features of the board’s fan speed, thermal, and voltage monitoring and control
subsystem include:
•
Monitoring of power supply voltages to detect levels above and below acceptable
values.
•
Smart fan control provided by the legacy I/O controller, delivering acoustically-
optimized thermal management.
Fan speed controllers and sensors are integrated
into the legacy I/O controller.
•
Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed according to thermal conditions.
•
Two thermal sensors (processor and a remote thermal sensor).
