Intel Desktop Board D865GVHZ Product Guide
•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.
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 10 on page 36 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)
Resume on Ring
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 & 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 two power connectors. See Figure 10 on page 36 for the location of the power connectors.
Fan Connectors
The desktop board has two chassis fan connectors (Intel Precision Cooling Technology) and one processor fan connector. See Figure 10 on page 36 for the location of the fan connectors.
Fan Speed Control (Intel® Precision Cooling Technology)
Intel Precision Cooling Technology automatically adjusts the chassis fan speeds depending on the system’s temperature. This feature reduces system fan noise by lowering the speed of the chassis fans connected to the front and rear chassis fan connectors. The processor fan connector is not controlled.
