The motherboard operates with Socket 370 for Intel PIIITM
processor. The CPU should always has a Heat Sink and cooling fan
attached to prevent overheating.
CPU Installation Procedure: Socket 370
1. Pull the lever sideways away from the socket then raise
the lever to a 90-degree angle.
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 or
cut edge then insert the CPU.
3. Press the lever down to complete installation.
4. Make sure the spec of the heatsink is good enough.
5. Please lock the fan on CPU very carefully, or you
will damage the resistor array even circuit line
on the mainboard.
