Installing Upgrade CPUs

The G586IPC is equipped with a 321-pin Zero Insertion Force (ZIF)

socket at location U27 of the system board. Refer to page 12 for the

location of the ZIF socket. This socket is designed for easy removal of

an old CPU and easy insertion of an upgrade CPU. The socket allows

you to carefully place the new CPU into its position. If you need to

apply excessive force to insert the CPU, you are not installing the CPU

correctly.

Warning:

Open the socket only if you are actually installing a CPU. The warranty

on the original CPU will be voided if the S/N seal is broken.

Before proceeding with the upgrade, take note of the following. The mi-

croprocessor and heat sink may be hot if the system has been running.

To avoid the possibility of a burn, power the system off and let the

processor and heat sink cool for 15 minutes.

The 321-pin ZIF socket consists of five rows of pin holes on each side.

To prevent improper CPU installation, the ZIF socket has a Plug/Keying

mechanism. Several holes in the socket are plugged so that the CPU

will go in only one way. If you cannot easily insert the CPU, verify that

pin 1 of the CPU is aligned with pin 1 of the socket.
