Special Features

Recovery from AC Power Loss
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.

PC Health Monitoring

This section describes the PC health monitoring features of the X8DTU/X8DTU-F. All
have an onboard System Hardware Monitor chip that supports PC health monitoring.
An onboard voltage monitor will scan these onboard voltages continuously: Onboard
voltage monitors for CPU1 Vcore, CPU2 Vcore, CPU1 DIMM, CPU2 DIMM, 5V,
5VSB, 12V, -12V, 3.3Vcc, 3.3VSB, VBAT and Vtt. Once a voltage becomes unstable,
a warning is given or an error message is sent to the screen. Users can adjust the
voltage thresholds to define the sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
CPU and chassis fans are controlled by Thermal Management via BIOS (under
Hardware Monitoring in the Advanced Setting).
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 independently from the CPU. Once it detects
that the CPU temperature is too high, it will automatically turn on the thermal fan
control to prevent any overheat damage to the CPU. The onboard chassis thermal
circuitry can monitor the overall system temperature and alert users when the chas-
sis temperature is too high.
To avoid possible system overheating, please be sure to provide adequate
airflow to your system.
