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 hit the power switch to turn it back
on) or for it to automatically return to a power- on state. See the Power Lost Con-
trol setting in the Advanced BIOS Setup section to change the setting. The default
setting is Last State.

PC Health Monitoring

This section describes the PC health monitoring features of the X7DA8+/X7DAE+.
All have an onboard System Hardware Monitor chip that supports PC health monitor-
ing.An onboard voltage monitor will scan the following voltages continuously: CPU
Cores, Chipset Voltage, +3.3V, +5V, +12V, -12V, +5V Standby 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
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 CPU overheat. The onboard chassis thermal circuitry can moni-
tor the overall system temperature and alert users when the chassis temperature
is too high.
CPU Fan Auto-Off in Sleep Mode
When the power is turned on, the CPU fan becomes active. It continues to operate
when the system enters Standby mode. When in sleep mode, the CPU will not run
at full power, thereby generating less heat.
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, if the system is running
low on virtual memory and there is insuffi cient hard drive space for saving the
