2.2 Installation of Processor (CPU) Installation of Processor (CPU)
Before you install the processor, make sure that you have an approved Heat Sink with
Cooling Fan. Without proper heat sink with cooling fan will damage the processor and
mainboard.
Caution
Caution ! ! According to the documentation from AMD, Duron™ and
Athlon™ processors require larger heat sink. The rotation speed of the
cooling fan is 5,500 RPM or above. Thermal grease must be applied
between the heat sink and the CPU to improve heat dissipation. Also,
ensure that the heat sink is fastened securely on the CPU.
To install your processor, please do the following:
1. Locate a small dot marked on top of the CPU. The marking indicate Pin 1 of the
CPU.
2. Locate the Socket Pin 1 marking on the mainboard.
3. Push the lever sideway and lift it
upwards to 90-degree angle. Insert
the CPU into the Socket. Please
make sure that the CPU Pin 1 is
insert to the socket Pin 1 location
4. Install an approved heat sink with
cooling fan for proper heat
dissipation. Falling to install a heat
sink with cooling fan may cause
overheating and burnout your CPU.
5. Snap back the lever into place.
Caution ! Be careful not to scrape the mainboard when mounting a
clamp-style processor fan to prevent damage to the mainboard.

Option 1: If you chose “Delay 4 Sec.” In the BIOS CMOS Setup, the function of
“PW” will be:
A. When system power is "OFF", press this switch, the system will power on.
B. When system power is "ON”, you can select two different mode:
Mode 1: Press the Power ON button and release (less than 4 seconds); the system
will be turned into Suspend mode (turn into the GREEN mode) When the system is in
Suspend mode:
!Press the Power on button (less than 4 seconds), the system will return to Full-
ON mode.
!Press and hold the Power On Button for more than 4 seconds, the system will
be powered off.
Mode 2: Press and hold the Power ON button for more than 4 seconds, the system
will be completely powered off.
Option 2: If you chose “Instant OFF.” In the BIOS CMOS Setup, it will operate like
normal ON / OFF Power button.
