4. Installing the

CPU and Cool-

ing Fan

Socket 370 Type proces-

sors can be used on the

Tomcat i810ef. Remember:

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.

Before the CPU is installed, the mainboard must be placed on a flat

surface. You should be able to insert the CPU into the slot with minimal,

but firm pressure. Do not press down hard on the CPU.
