Processor Upgrade
The system board has a Slot 1 242-pin edge connector and a
universal retention mechanism for securing in place a
Celeron, Pentium II, or Pentium III processor cartridge
(depending on your system model).
Before starting the processor upgrade, you must first
determine the processor your system has, as the type of
processor determines the installation procedure you use.
To identify a Pentium II or a Pentium III processor, check the
top of the cartridge. To identify a Celeron processor, check
the rear of the cartridge.
To remove the processor, see “Removing the Celeron or
Pentium III Processor Cartridge” or see “Removing the
Pentium II Processor Cartridge” in the following sections.
To install the upgrade processor, see “Installing the Celeron
or Pentium III Processor Cartridge” or see “Installing the
Pentium II Processor Cartridge” in the following sections.
!
CAUTION
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 the installation
instructions provided with the upgrade processor
and the procedures in the following sections.
Ensure that you have the correct heat sink for the
processor being installed. The Celeron,
Pentium II, and Pentium III each use a different
heat sink. Do not use the heat sink from the
removed processor.
