2. The ServerGuide program stores information about the server model, serviceprocessor, hard disk drive controllers, and network adapters. Then, the programchecks the CD for newer device drivers. This information is stored and thenpassed to the operating-system installation program.3. The ServerGuide program presents operating-system partition options that arebased on your operating-system selection and the installed hard disk drives.4. The ServerGuide program prompts you to insert your operating-system CD andrestart the server. At this point, the installation program for the operating systemtakes control to complete the installation.Installing your operating system without using ServerGuideIf you have already configured the server hardware and you are not using theServerGuide program to install your operating system, complete the following stepsto download the latest operating-system installation instructions from the IBM Website.Note: Changes are made periodically to the IBM Web site. The actual proceduremight vary slightly from what is described in this document.1. Go to http://www.ibm.com/systems/support/.2. Under Product support, click System x.3. From the menu on the left side of the page, click System x support search.4. From the Task menu, select Install.5. From the Product family menu, select System x3250 M3.6. From the Operating system menu, select your operating system, and then clickSearch to display the available installation documents.Using the integrated management moduleThe integrated management module (IMM) is a second generation of the functionsthat were formerly provided by the baseboard management controller hardware. Itcombines service processor functions, video controller, and (when an optionalvirtual media key is installed) remote presence function in a single chip.For more information about IMM, see the Integrated Management Module User'sGuide at http://www.ibm.com/systems/support/supportsite.wss/docdisplay?lndocid=MIGR-5079770&brandind=5000008The IMM supports the following basic systems-management features:v Environmental monitor with fan speed control for temperature, voltages, fanfailure, and power supply failure.v DIMM error assistance. The Unified Extensible Firmware Interface (UEFI)disables a failing DIMM that is detected during POST, and the IMM lights theassociated system error LED and the failing DIMM error LED.v System-event log (SEL).v ROM-based IMM firmware flash updates.v Auto Boot Failure Recovery (ABR).v A virtual media key, which enables remote presence support (remote video,remote keyboard/mouse, and remote storage).v Nonmaskable interrupt (NMI) detection and reporting.v Automatic Server Restart (ASR) when POST is not complete or the operatingsystem hangs and the operating system watchdog timer times-out.
