Installing Upgrade CPUs

The G586OPA is equipped with a 320-pin Zero
Insertion Force (ZIF) socket at location U22 of the
system board. This socket is designed for easy removal
of the old CPU and easy insertion of the 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, the installation is being done incorrectly.
Warning:
Open the socket only if actually installing a CPU. The
warranty on the original CPU will be voided if the S/N
seal is broken.
Do not change any factory CPU speed jumper settings.
You do not need to change any jumpers to properly
install the 3.3V Pentium Upgrade Processor.
Before proceeding with the upgrade, take note of the
following. The microprocessor 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 10 minutes.
The 320-pin ZIF socket consists of the four rows of pin
holes on each side. To avoid improper installation, the
ZIF socket is designed with a Plug/Keying mechanism.
There are several holes in the socket that are plugged so
the CPU will only go in one way. If you are unable to
easily insert the CPU, please verify that pin 1 of the
CPU is being plugged into pin 1 of the socket. The
location of the pin 1 is shown on the next page.
