Intel Desktop Board DH61WW Product Guide Trusted Platform Module (TPM) Support Intel Desktop Board DH61WW provides a header to connect to an external TPM. The header is shown in Figure 1, P on page 12 and the header pinout is listed in Table 8 on page 45. TPMs are designed to enhance platform security 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. TPMs shield unencrypted keys and platform authentication information from softwarebased attacks. Fan Speed Control and Hardware Monitoring The features of the hardware monitoring and fan speed control include: • Thermal sensors in the processor and the Intel PCH, as well as near the processor voltage regulators and system memory • Monitoring of system voltages to detect levels above or below acceptable values • Thermally monitored closed-loop fan control for all three fans that can adjust fan speed as needed • Support for 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. Power Management Power management is implemented at several levels, including software support through the Advanced Configuration and Power Interface (ACPI) and the following hardware support: • Power connectors • Fan headers • LAN wake capabilities • Instantly Available PC technology (Suspend to RAM) • +5 V standby power indicator LED • Wake from USB • PCI Power Management Event signal (PME#) wakeup support • PCI Express WAKE# signal support • Wake from serial devices • Wake from PS/2 devices Software Support ACPI ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the Desktop Board requires an operating system that provides full ACPI support. 20

Intel Desktop Board DH61WW Product Guide
Trusted Platform Module (TPM) Support
Intel Desktop Board DH61WW provides a header to connect to an external TPM.
The
header is shown in Figure 1, P on page 12 and the header pinout is listed in Table 8 on
page 45.
TPMs are designed to enhance platform security 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.
TPMs shield unencrypted keys and platform authentication information from software-
based attacks.
Fan Speed Control and Hardware Monitoring
The features of the hardware monitoring and fan speed control include:
•
Thermal sensors in the processor and the Intel PCH, as well as near the processor
voltage regulators and system memory
•
Monitoring of system voltages to detect levels above or below acceptable values
•
Thermally monitored closed-loop fan control for all three fans that can adjust fan
speed as needed
•
Support for 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.
Power Management
Power management is implemented at several levels, including software support
through the Advanced Configuration and Power Interface (ACPI) and the following
hardware support:
•
Power connectors
•
Fan headers
•
LAN wake capabilities
•
Instantly Available PC technology (Suspend to RAM)
•
+5 V standby power indicator LED
•
Wake from USB
•
PCI Power Management Event signal (PME#) wakeup support
•
PCI Express WAKE# signal support
•
Wake from serial devices
•
Wake from PS/2 devices
Software Support
ACPI
ACPI gives the operating system direct control over the power management and Plug
and Play functions of a computer.
The use of ACPI with the Desktop Board requires an
operating system that provides full ACPI support.
