HARDWARE INSTALLATION
2.1 Central Processing Unit: CPU
The mainboard operates with Intel® CeleronTM or Pentium® III processor.
The mainboard uses a CPU socket called Socket 370 for easy CPU installation. The CPU should always have a Heat Sink and a cooling fan attached to
prevent overheating.
2.1-1 CPU Installation Procedures
1. Pull the lever sideways away
from the socket. Then, raise
the lever up to a 90-degree
angle.
Open Lever
Sliding
Plate
2. Locate Pin 1 in the socket
and look for the white dot or
cut edge in the CPU. Match
Pin 1 with the white dot/cut
edge. Then, insert the CPU.
It should insert easily.

1. If the CPU Core/Bus ratio is already fixed, adjusting the SW1 will not
change the CPU Core/Bus ratio. If the Core/Bus ratio is not fixed by the
CPU, then you can adjust the SWI to change the Core/Bus ratio.

2.1-3 CPU Bus Frequency Selector: J9
The J9 is used to set the CPU Bus Frequencies from 66MHz to 100MHz.
When J9 is shorted, this will automatically detect the CPU Bus Frequency.
When J9 is open, if you used 66MHz CPU, the Bus Frequency will be set
virtually into 100MHz.

NOTE:
1. This feature works with 66MHz FSB only.
2. If your CPU FSB supports 66MHz and you want to run it
on 100MHz FSB, the J9 should be open. The AGP Bus will be
set to run at 100MHz x 2/3=66MHz to make it stable.

These connectors support system cooling fan with +12V. It supports three
pin head connector. When connecting the wire to the connector, always
take note that the red wire is the positive and should be connected to the
+12V, the black wire is Ground and should be connected to GND. If your
mainboard has System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of this function.
