Processor Upgrade
The system has an S.E.C. processor cartridge that connects to
a Slot 1 242-pin edge connector on the system board. The
processor cartridge is secured to the connector in a retention
mechanism. When a cartridge is inserted in the connector, the
VID pins program the voltage regulator on the system board
to the required voltage for the processor.
NEC recommends that you contact your NEC
dealer or NEC service center for assistance in
upgrading your processor.
Incorrect installation of the processor cartridge
and heat sink can damage the processor, system
board, or both. Carefully follow all installation
instructions provided with your upgrade
processor and the procedures in the following
sections.
Ensure that you have the correct heat sink for the
processor being installed. Celeron, Pentium II,
and Pentium III processors use different heat
sinks. Do not use the heat sink from the removed
processor.
When upgrading the processor, first remove the processor
currently installed in the system, then install the upgrade
processor.
Before starting, you must first determine which processor
your system has, as the type of processor determines the
installation procedure you use. Check the side of the cartridge
for processor identification.
