Special Features

Recovery from AC Power Loss
The Basic Input/Output 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.

PC Health Monitoring

This section describes the PC health monitoring features of the motherboard. All
have an onboard System Hardware Monitor chip that supports PC health monitor-
ing. An onboard voltage monitor will scan these onboard voltages continuously:
Onboard voltage monitors for CPU 1 Vcore, CPU 2 Vcore, +3.3V, +5V, +12V, +3.3V
Stdby, +5V Stdby, CPU 1 DIMM, CPU 2 DIMM, and VBAT. 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 the
Hardware Monitoring section 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 the CPU from overheating. The onboard chassis thermal circuitry
can monitor the overall system temperature and alert users when the chassis
temperature is too high.
Note: 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
