Microprocessor 2socket (CPU2)Microprocessor 1socket (CPU1)v If only one microprocessor is installed, make sure that it is installed inmicroprocessor socket 1 (system-board identifier CPU1). Microprocessor 1supports both the startup and application processes.v If you install a second microprocessor in the server, the server operates as asymmetric multiprocessing (SMP) server, and operating-system applicationprograms can distribute the processing load between the microprocessors. Thisenhances performance for database and point-of-sale applications, integratedmanufacturing solutions, and other applications. Microprocessor 2 is installed insocket 2 (system-board identifier CPU2).v Read the documentation that comes with the microprocessor to determinewhether you must update the BIOS code in the server. To download the mostcurrent level of BIOS code for your server, go to http://www.ibm.com/servers/eserver/support/xseries/index.html and follow the instructions.v (Optional) Obtain an SMP-capable operating system.
