Intel Desktop Board DQ45EK Product Guide Intel® Trusted Platform Module (Intel® TPM) The Intel TPM component is designed to enhance platform security above and beyond the capabilities of today's software by providing a protected space for key operations and other security critical tasks. Using both hardware and software, the TPM protects encryption and signature keys at their most vulnerable stages-operations when the keys are being used unencrypted in plain-text form. The TPM is specifically designed to shield unencrypted keys and platform authentication information from softwarebased attacks. NOTE The Intel TPM uses the onboard coin-cell battery (CR2032) to maintain its monotonic counters. One major function of the monotonic counters is for anti-replay protection of the internal Intel TPM data. If the battery is removed or exhausted, the Intel TPM data will be deleted in accordance with Trusted Computing Group guidelines. Please read the Intel TPM user guide and back-up Intel TPM keys and data before removing the battery. Hardware Management Features The hardware management features of Intel Desktop Board DQ45EK 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 The board's fan speed, thermal, and voltage monitoring and control features include the following: • Monitoring of power supply voltages to detect levels above and below acceptable values • Intel Quiet System Technology fan speed control, delivering acoustically-optimized thermal management NOTE Memory must be installed in the Channel A socket to enable Intel Quiet System Technology. • Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed according to thermal conditions. • Fan speed controllers and sensors integrated into the ICH10DO 24

Trusted Platform Module (Intel
®
TPM)
The Intel TPM component is designed to enhance platform security above and beyond
the capabilities of today’s software by providing a protected space for key operations
and other security critical tasks.
Using both hardware and software, the TPM protects
encryption and signature keys at their most vulnerable stages—operations when the
keys are being used unencrypted in plain-text form.
The TPM is specifically designed
to shield unencrypted keys and platform authentication information from software-
based attacks.
NOTE
The Intel TPM uses the onboard coin-cell battery (CR2032) to maintain its monotonic
counters.
One major function of the monotonic counters is for anti-replay protection
of the internal Intel TPM data.
If the battery is removed or exhausted, the Intel TPM
data will be deleted in accordance with Trusted Computing Group guidelines.
Please
read the Intel TPM user guide and back-up Intel TPM keys and data before removing
the battery.
Hardware Management Features
The hardware management features of Intel Desktop Board DQ45EK 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
The board’s fan speed, thermal, and voltage monitoring and control features include
the following:
•
Monitoring of power supply voltages to detect levels above and below acceptable
values
•
Intel Quiet System Technology fan speed control, delivering acoustically-optimized
thermal management
NOTE
Memory must be installed in the Channel A socket to enable Intel Quiet
System Technology.
•
Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed according to thermal conditions.
•
Fan speed controllers and sensors integrated into the ICH10DO
