    Server Software and Utilities System Configuration Utility (SCU) The server was pre-configured at the factory using the System Configuration Utility (SCU). This means that the server’s hardware (processor modules, memory, cache, mass storage devices, expansion boards, etc.) has been identified and configured for optimum performance.

  • Page 27: Configuring Expansion Boards

    Server Software and Utilities Configuring Expansion Boards Each time you add, remove, or relocate any EISA/ISA/PCI expansion board, you need to run the SCU to identify their operating characteristics, server resource requirements, and slot locations. Based on this information, the SCU will then automatically assign the proper server resources to EISA expansion boards, enable PCI boards, and inform you as to what jumper or switch settings need to be manually set on ISA expansion boards to avoid resource conflicts.
  • Page 28 Server Software and Utilities Start the SCU in one of three ways: 1. During the Quick Launch boot process, if a DOS partition was created, the SCU was copied to the partition on the hard disk drive. This allows you to run the SCU anytime from the DOS partition.
