CPU Installation
Several types of CPUs (75 through 233MHz) can be used on the
S1576S. Please refer to page 13 for the correct CPU jumper settings
for your particular CPU.
Remember:
s
The CPU is a sensitive electronic component and it can easily be
damaged by static electricity. Do not touch the CPU pins with your
fingers.
s
When installing the CPU into the socket, match the CPU pins to
the socket pins. Note that one corner of the socket’s top is different
from the other three corners. Likewise, one corner of the CPU’s
bottom is different from the other three corners. Line the unique
socket corner up with the unique CPU corner.
s
Before the CPU is installed, the mainboard must be placed on a
flat surface. You should be able to insert the CPU with minimal,
but firm, pressure. Do not press down hard on the CPU.
s
An assembly composed of both a cooling fan and a heat sink is
required to protect the CPU from being damaged.
CPU Installation Procedure:
1. Make sure the ZIF socket
lever is up. To raise the lever,
pull it a bit horizontally, and
then as far as it will go
vertically. The top plate will
slide back to open up the
socket.
2. Align the CPU and socket
pin 1 corners. The pins on
the bottom of the CPU
should align with the holes in
the socket.
3. Insert the CPU into the socket. It should slip in easily. If it does
not, adjust the position of the lever a little.
