1-4 Special Features

Recovery from AC Power Loss
Basic I/O System (BIOS) provides a setting for you to determine how
the system will respond when AC power is lost and then restored to
the system. You can choose for the system to remain powered off, (in
which case you must press the power switch to turn it back on), or for
it to automatically return to a power-on state. See the Advanced BIOS
Setup section to change this setting. The default setting is Last State.

1-5 PC Health Monitoring

This section describes the PC health monitoring features of the board.
All have an onboard System Hardware Monitoring chip that supports PC
health monitoring. An onboard voltage monitor will scan these onboard
voltages continuously: +1.8V, +3.3V, +5V, +/- 12V, +3.3V Stby, +5V
Stby, VBAT, HT, Memory Temperature, PCH Temperature, and System
Temperature. Once a voltage becomes unstable, a warning is given, or
an error message is sent to the screen. The user can adjust the voltage
thresholds to define the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control
PC health monitoring in the BIOS can check the RPM status of the cool-
ing fans. The onboard CPU and chassis fans are controlled by Thermal
Management via SIO.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time
and will turn on the thermal control fan whenever the CPU temperature
exceeds a user-defined threshold. The overheat circuitry runs indepen-
dently from the CPU. Once the thermal sensor detects that the CPU
temperature is too high, it will automatically turn on the thermal fans to
prevent the CPU from overheating. The onboard chassis thermal circuitry
can monitor the overall system temperature and alert the user when the
chassis temperature is too high.
Note: To avoid possible system overheating, please be sure to
provide adequate airflow to your system.
