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 hit the power switch to turn it back on
when the power is restored.) You can also select "Last State" from the Advanced
BIOS Setup section. In this case, the system will be restored to its original state
before the power outage. The default setting is Last State.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the PDSMA+/PDS-
MA-E+. The motherboard has an onboard System Hardware Monitor chip that
supports PC health monitoring.
Onboard Voltage Monitors for the CPU Cores, Chipset Voltage
(+1.5V), Memory Voltage (+1.8V), +3.3V, +3.3V Standby, +5V,
+
5V
Standby,

12V,
−
12V, VTT FSB and VBAT.
The onboard voltage monitor will scan these voltages continuously. Once a voltage
becomes unstable, it will give a warning or send an error message to the screen.
The user can adjust the voltage thresholds to define the sensitivity of the voltage
monitor.
Fan Status Monitor with Firmware Speed Control
The PC health monitor can check the RPM status of the cooling fans. The onboard
fans are controlled by Thermal Management via BIOS.
CPU Overheat/Fan Fail LED and Control
This feature is available when the user enables the CPU overheat warning option
in the BIOS. This allows the user to define an overheat temperature. When this
temperature reaches the threshold, the CPU thermal trip feature will be activated
and it will send a signal to the Speaker LED and, at the same time, the CPU speed
will decrease. It will also activate the alarm if a fan failure occurs.
