The G586VPA supports the CPU clock of 100MHz if the

Installing Upgrade CPUs
The G586VPA is equipped with a 320-pin Zero
Insertion Force (ZIF) socket at location U1 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.
The jumpers below are for factory testing only and
should always be set to their default configurations.
Reconfiguring these jumpers will cause problems with
your system board.
J4: 2-3 On
J5: 2-3 On

The 320-pin ZIF socket consists of four rows of pin
holes on each side. To avoid improper installation, the
ZIF socket is designed with a Plug/Keying mechanism.
