3. Hardware Description
CPU Installation
The board supports a single Intel Celeron or Pentium III processor. The processor’s
VID pin automatically sets the CPU board’s voltage variation ratio to the required
processor voltage. The host bus speed is also selected automatically.
The processor
is connected to the CPU board via a 370-pin ZIF PPGA socket.
The CPU board supports the processors listed in the table below.

The ZIF PPGA socket has a lever to hold the processor in place.
Ensure that the
notch on the side of the processor is aligned with the notch in the socket.
After installing the processor in the 370 socket, check that the configuration settings
relating to the processor model and speed are correct. The CPU must always be fitted
with a heat sink and fan to prevent overheating.
Note!
To avoid problems such as unstable operation and system hang-up
due to CPU overheating, ensure that the heat sink contacts firmly
with the top surface of the CPU.
