The ServerGuide programdetects the server model and optional hardware devices that are installed and usesthat information during setup to configure the hardware. The ServerGuideprogram simplifies operating-system installations by providing updated devicedrivers and, in some cases, installing them automatically.You can download a free image of the ServerGuide Setup and Installation CD orpurchase the CD from the ServerGuide fulfillment website at http://www.ibm.com/systems/management/serverguide/sub.html. To download the freeimage, click IBM Service and Support Site.Note: Changes are made periodically to the IBM website. The actual proceduremight vary slightly from what is described in this document.The ServerGuide program requires a supported IBM server with an enabledstartable (bootable) CD drive. In addition to the ServerGuide Setup and InstallationCD, you must have your operating-system CD to install the operating system.102 IBM System x3850 X5 and x3950 X5 Types 7145, 7146, 7143, and 7191: Installation and User's Guide
