3.11 CPU Installation
Many types of Pentiums (75 thru 233 MHz) and Cyrix/AMD CPUs can
be used on the S1564. Please refer to the previous pages for the correct
CPU jumper settings for your board.
w
The CPU is a sensitive electronic component and it can be easily
damaged by static electricity. Do not touch the CPU pins with your
fingers.
w
When installing the CPU into the socket, match the CPU pins to the
socket pins.
w
Before 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.
w
A 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.
