This subsection provides the procedure for upgrading
and configuring the Pentium II Processor in your
system. The system board has a socket for the
processor. Figure 5-4, A illustrates the location for the
processor in your system.
Notice: Electrostatic discharge (ESD) can damage
components; place them on an antistatic surface. Modify
the system board using an antistatic wrist strap
attached to chassis ground.
Warning: If the system has been running, any
processor and heat sink already installed on the board
will be hot. To avoid the possibility of a burn, let the
components cool for 10 minutes before continuing with
the procedures described here
