Working with microprocessors Your server comes with an intel Pentium III microprocessor. This microprocessor incorporates MMX technology with built-in ECC L2 cache. For the latest information about microprocessor upgrades available for your server, 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 section. When you install an additional microprocessor, your Netfinity 3500 M10 server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between microprocessors. This can enhance performance for database applications, integrated manufacturing solutions, and other applications. The voltage regulator function is built into the system board. This feature supports each microprocessor on the system board. If you install a second microprocessor, it must operate at the same voltage as the primary microprocessor to ensure proper operation of the voltage regulator feature. Installing a second microprocessor Attention OS for SMP must be installed before the system will recognize a second microprocessor. Before you begin Read "Safety Information" on page 196 Thoroughly review the documentation that comes with the microprocessor, so that you can determine whether you need to update the server BIOS. ServerGuide includes IBM Update Connector, a dial-up program that keeps your BIOS and device drivers current. You also can obtain the latest level of BIOS for your server through the World Wide Web and the IBM PC Company Bulletin Board System (BBS). See "Online Support" on page iv for the appropriate World Wide Web addresses. Turn off the server. Disconnect all cables attached to the server and remove the server cover (see "Preparing to install and remove options" on page 73). Read "Accessing the system board" on page 82.
