Clearing Passwords on page 48.
Chassis Intrusion
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 20 on page 39 for the location of the chassis
intrusion header.
Power Management Features
Power management is implemented at several levels, including:
• Advanced Configuration and Power Interface (ACPI)
• Hardware support:
⎯ Power connectors
⎯ Fan connectors
⎯ Suspend to RAM (Instantly Available PC technology)
⎯ Wake from USB
⎯ Wake from PS/2 keyboard/mouse
⎯ PME# wakeup 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.
Power Connectors
The desktop board has three power connectors. See Figure 24 on page 45 for the location of the
power connectors.
Fan Connectors
The desktop board has a 4-pin processor fan header and two 3-pin chassis fan headers. See
Figure 23 on page 44 for the location of the fan headers.
Fan Speed Control (Intel
®
Precision Cooling Technology)
Intel Precision Cooling Technology automatically adjusts the processor fan speed based on the
processor thermal diode temperature and adjusts the chassis fan speeds depending on the system
temperature. System fan noise may be reduced by operating controlled chassis and processor fans
at the minimum necessary speeds.
The processor and chassis fan speed control features can be disabled independently through the
desktop board BIOS. Disabling the processor fan speed control will result in the fan operating at
full speed if it is not a self controlled fan. It is recommended that processor fan speed control
remain enabled (default BIOS setting) when using the processor fan heat-sink included with Intel
®
boxed processors. Disabling the chassis fan speed control results in chassis fans always operating
