Desktop Board Features Trusted Platform Module (TPM) The TPM 1.2 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.

Trusted Platform Module (TPM)
The TPM 1.2 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.

Hardware Management Features
The hardware management features of Desktop Board DQ965GF 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 Quiet System Technology, delivering acoustically-optimized thermal
management
NOTE
Memory must be installed in the Channel A, DIMM 0 socket to enable Intel®
Quiet System Technology.
•
Fan speed controllers and sensors integrated into the ICH8
•
Thermal sensors in the processor, GMCH, and ICH8 plus an onboard remote sensor
•
Thermally monitored closed-loop fan control, for all onboard fans, that can adjust
fan speed or switch the fans off as needed
Chassis Intrusion Detection
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 26 on
page 51 for the location of the chassis intrusion header.
