Automatic Fan Control
With the system's power switched on, the processor's fan will
rotate only if the temperature of the processor is over 25
saves energy, prevents system overheat, prolongs fan life and
implements a silent system.
Dual Function Power Button
Depending on the setting in the BIOS setup, this switch will allow
your system to enter the Soft-Off or Suspend mode. "Soft-Off By
PWRBTN" in the Power Management Setup (Chapter 3) allows
you to select the method of powering off your system.
External Modem Ring-on
The Modem Ring-on feature allows the Soft Power Down (Soft-
Off) PC to power-on to respond to incoming calls. Enable this
function in the "Resume On Ring" field and select an IRQ channel
for the external modem in the "Modem Use IRQ" field. Refer to
the Power Management Setup section (Chapter 3) for more
information.
Note:
This feature supports external modem only. If you are using
this function, make sure to turn on the power of the modem
prior to powering-off the system.
RTC Timer to Power-on the System
The RTC installed on the system board allows your system to
automatically power-on on the set date and time. Set the date and
time you would like your system to power-on in the "Resume On
Alarm" field of the Power Management Setup (Chapter 3).
Virus Protection
Most viruses today destroy data stored in hard drives. The system
board is designed to protect the boot sector and partition table
of your hard disk drive. If an attempt is made to write to the
boot sector or partition table of the hard disk drive, the BIOS will
halt the system and an error message will appear. Refer to the
"Virus Warning" field in the BIOS Features Setup of the Award
BIOS (Chapter 3).
