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. 21

Desktop Board Features
21
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.
