Introduction
1.1.3 Intelligence
CPU Fan Protection
The CPU Fan Protection function has the capability of monitoring the
CPU fan when the system boots. Once it has detected that the CPU
fan did not rotate, 5 warning beeps will sound then the system will
automatically power-off. This preventive measure has been added to
protect the CPU from damage and insure a safe computing environ-
ment.
CPU Temperature Protection
The CPU Temperature Protection function has the capability of
monitoring the CPU's temperature during system boot-up. Once the
system has detected that the CPU's temperature exceeded the
temperature limit defined in the BIOS, 5 warning beeps will sound then
the system will automatically power-off.
Dual Function Power Button
Depending on the setting in the "Soft-Off By PWR-BTTN" field of
the Power Management Setup, this switch will allow the system to
enter the Soft-Off or Suspend mode.
Wake-On-Ring
This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
from an external modem or respond to calls from a modem PCI
card that uses the PCI PME (Power Management Event) signal to
remotely wake up the PC.

Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of 720mA.
