Upgrading a Microprocessor Your computer comes with an Intel® microprocessor installed on the system board. It can be either a Pentium or a Pentium with MMX technology. (To see which microprocessor is installed in your computer, refer to the Configuration/Setup Utility Program.) For the latest information on microprocessor upgrades available for your computer, contact your place of purchase or your IBM reseller. If you do upgrade the microprocessor, use the instructions that come with the upgrade along with the instructions in this publication. CAUTION: The microprocessor and heat sink will be hot if the computer has been running. To avoid the possibility of a burn, if the computer has been on, let the microprocessor and heat sink cool for 10 minutes before continuing with the procedure. Before you begin Read "Electrical Safety" on page 4 and "Handling Static-Sensitive Devices" on page 5. Read the instructions that come with the new microprocessor. Turn off the computer. Disconnect all cables attached to the computer and remove the computer cover (see "Disconnecting Cables and Removing the Cover" on page 6). Chapter 3. Working with Options on the System Board 21
