1-3 Special Features
Recovery from AC Power Loss
The Basic I/O System (BIOS) provides a setting that determines 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 the power-on state. See the
Advanced BIOS Setup section for this setting. The default setting is
Last State
.
1-4 PC Health Monitoring
This section describes the features of PC health monitoring of the motherboard.
This motherboard has an onboard System_Hardware_Monitor chip that supports
PC health monitoring. An onboard voltage monitor will scan the following onboard
voltages continuously: +3.3V, 3.3VSB, +5V, CPU, memory, chipset, and battery
voltages. Once a voltage becomes unstable, a warning is given, or an error mes-
sage 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
The PC health monitor chip can check the RPM status of a cooling fan. The on-
board cooling and chassis fans are controlled by firmware thermal management
via IPMI interface.
Environmental Temperature Control
A thermal management controller 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
the CPU temperature is too high, the thermal control manager will automatically turn
on the thermal fan control to prevent the CPU from overheating, and the overheat
beep will be activated to alert the user when the temperature is too high.
Note
: To avoid possible system overheating, please be sure to provide
adequate airflow to your system.
System Resource Alert
This feature is available when used with SuperDoctor® 5 in the Windows or Linux
environment. SuperDoctor is used to notify the user of certain system events. For
example, you can configure SuperDoctor to provide you with warnings when the
