CPU Installation

The system board comes with a zero-insertion force (ZIF) CPU socket
for easy installation.

Follow these steps to install a Pentium CPU:

Lift up the socket lever.

Insert the CPU to the socket. Make sure that the notched corner
of the CPU matches the pin 1 indicator on the socket.

Be careful not to bend any pins.

Pull down the socket lever.
