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 sys-
tem to remain powered off (in which case you must hit the power switch to turn it
back on) or for it to automatically return to a power- on state. See the Power Lost
Control setting in 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 SUPER X6DVA-
4G2/X6DVA-EG2. All have an onboard System Hardware Monitor chip that sup-
ports PC health monitoring.
Onboard Voltage Monitors for the CPU Cores, Chipset Voltage,
Memory Voltage, +3.3V, +5V, +12V, -12V, +3.3V Standby, and
+5V Standby
An onboard voltage monitor will scan these voltages continuously. Once a voltage
becomes unstable, a warning is given or an error message is sent to the screen.
Users can adjust the voltage thresholds (in Supero Doctor III) to defi ne the sen-
sitivity of the voltage monitor.
Fan Status Monitor with Fan Speed 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 the BIOS.
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 reaches a user-
defi ned threshold. The overheat circuitry runs independently from the CPU. It can
continue to monitor for overheat conditions even when the CPU is in sleep mode.
Once it detects that the CPU temperature is too high, it will automatically turn on
the thermal control fan to prevent any overheat damage to the CPU. The onboard
chassis thermal circuitry can monitor the overall system temperature and alert
users when the chassis temperature is too high.
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning function
in the BIOS. This allows the user to defi ne an overheat temperature.
