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 25oC. This
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.
RTCTimer 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).

2.2.2 Installing a Processor
The system board is equipped with a 321-pin Zero Insertion
Force (ZIF) socket The ZIF socket is designed for easy removal of
an old processor and easy insertion of an upgrade processor. If
you need to apply excessive force to insert the processor, you are
not installing the processor correctly.
1. To raise the handle of the ZIF socket, push it down, slightly pull
it out to the side, then raise it as far as it will go. It may be
necessary to initially apply a small amount of sideways force to
free the handle from its retaining “tab”. Once clear of the “tab”,
the handle will open relatively easily. The top plate will slide
back.
2. Insert the processor until the pins are in their corresponding
holes. Make sure pin 1 of the processor is aligned with pin 1
of the socket. To prevent improper processor installation, the
ZIF socket has a Plug/Keying mechanism. Several holes in the
socket are plugged so that the processor will go in only one
way.
3. Push the handle down until the handle locks into place. The
top plate will slide forward.
Warning:
The processor must be kept cool by using a fan with
heatsink. Otherwise, the processor will overheat and damage
the processor and the system board.
