1.4 Special Features
1.4.1 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 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 .
1.5 PC Health Monitoring
This section describes the PC health monitoring features of the RES-32XR3/FIO
motherboard. All have an onboard System Hardware Monitor chip that supports PC
health monitoring. An onboard voltage monitor will scan these onboard voltages
continuously:
CPU1 Vcore, CPU2 Vcore, CPU1 Vtt, CPU2 Vtt, CPU1 DIMM, CPU2 DIMM,
1.1V, 1.5V, 1.8V, 3.3V, 12V, 5V, 3.3 Vsb, 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 define the sensitivity of the
voltage monitor.
1.5.1 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 in the BIOS (under
Hardware Monitoring in the Advanced section).
1.5.2 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-defined
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 any overheat damage to the CPU. The onboard chassis thermal
