Page 36 highlights

Replacing a Microprocessor Attention: The presence of 5 V standby power might result in damage to your hardware unless you disconnect the power cord from the wall before opening the computer. Your computer comes with an Intel® Pentium®II microprocessor installed on the system board. For the latest information on microprocessor upgrades available for your computer, contact your IBM reseller or IBM marketing representative. If you do upgrade the microprocessor, use the instructions that come with the upgrade along with the instructions in this publication. Note: Upgrading a processor may require a BIOS update. After replacing or upgrading your processor, you may get a '167' POST error code. If you get this error, you must run the flash utility again. See Using Your Personal Computer for error code information. 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 and all other connected devices. Disconnect all cables attached to the computer and remove the computer cover (see "Disconnecting Cables and Removing the Cover" on page 6). Obtain a flash diskette for updating the system BIOS. If you do not have a flash diskette, refer to Updating the System BIOS in Using Your Personal Computer. Obtain a copy of the flash utility on diskette. 22 Installing Options in Your Personal Computer
