Desktop Board Features

If both the supervisor and user passwords are set, you must enter either the supervisor password or the user password to access Setup. Setup options are then available for viewing and changing depending on whether the supervisor or user password was entered.

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 15 on page 42 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

Fan Speed Control

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 15 on page 42 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 15 on page 42 for the location of the fan connectors.
