3.10 CPU Installation

Several types of CPUs (75 thru 200MHz) can be used on S1471. Please refer to section 3.2 for the correct CPU jumper settings for your board.

wThe CPU is a sensitive electronic component and it can be easily damaged by static electricity. Do not touch the CPU pins with your fingers.

wWhen installing the CPU into the socket, match the CPU pins to the socket pins.

wBefore the CPU is installed, the mainboard must be placed on a flat plane. You should be able to insert the CPU with minimal pressure. Do not push down hard, use firm pressure.

wA cooling fan and heat sink assembly is required to protect the CPU from being damaged.

1.Make sure the ZIF socket lever is up. To raise the lever, pull it out to the side a little and raise it as far as it will go. The top plate will slide back.

2.Align the CPU and socket Pin 1 corners. The pins on the bottom should align with the rows of holes in the socket.

3.Insert the CPU in the socket. It should insert easily. If it does not, adjust the position of the lever a little.

4.Press the lever down. The top plate will slide forward. You will feel some resistance as the pressure starts to secure the CPU in the socket. This is normal and will not damage the CPU.

The lever should snap into place at the side of the socket.
