Desktop Board Features

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.

For instructions on resetting the password, see Clearing Passwords on page 52.

Hardware Management Features

The hardware management features of Desktop Board DG35EC enable the board to be compatible with the Wired for Management (WfM) specification. The board has several hardware management features including the following:

Fan speed monitoring and control

Thermal and voltage monitoring

Chassis intrusion detection

Hardware Monitoring and Fan Speed Control

The features of the hardware monitoring and fan speed control include:

Monitoring of power supply voltages to detect levels above and below acceptable values

Fan speed controllers and sensors integrated into the legacy I/O controller

Thermal sensors in the processor, GMCH, and ICH8, plus an onboard remote sensor

Thermally monitored closed-loop fan control, for all onboard fans, that can adjust fan speed or switch the fans off as needed

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 23 for the location of the chassis intrusion header.
