1-3 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
.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the X8DTT-H/-HF/-
HIBX/-HIBXF/-HIBQ/-HIBQF. All have an onboard System Hardware Monitor chip
that supports PC health monitoring. An onboard voltage monitor will scan these
onboard voltages continuously: CPU1 VCore, CPU2 VCore, +5Vin,
12Vcc (V),
VP1 DIMM, VP2 DIMM, +3.3Vcc (V), and Battery Voltage. 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 defi ne 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-defi ned
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
airfl ow to your system.
System Resource Alert
This feature is available when used with Supero Doctor III in the Windows OS
environment or used with Supero Doctor II in Linux. Supero Doctor is used to
notify the user of certain system events. For example, you can also confi gure
