Installing Upgrade CPUs
The G586IPB/E is equipped with a 321-pin Zero Insertion Force (ZIF)
socket at location U25 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 10 minutes.
