Setup Utility Program Attention A customized setup configuration (other than default settings) might exist on the computer you are servicing. Running the Setup Utility program might alter those settings. Note the current configuration settings and verify that the settings are in place when service is complete. To start the Setup Utility program, see "Setup Utility Program." The Setup Utility (configuration) program is stored in the permanent memory of the computer. This program includes settings for the following: Devices and I/O Ports Date and Time Security Start Options Advanced Setup ISA Legacy Resources Rapid Resume Manager To run the Setup Utility program, do the following: 1. Power-off the computer and wait for a few seconds until all in-use lights go off. 2. Power-on the computer. 3. When the Setup Utility prompt appears on the screen during start-up, press F1. The Setup Utility menu appears. 4. Follow the instructions on the screen. 5. When finished, select System Summary to verify that any configuration changes have been accepted. Adapter Configuration To add adapters to past generations of ISA computers, a variety of switches are provided on the adapters. These switches control the assignment of computer resources such as interrupt request (IRQ) lines, direct memory access (DMA) channels, and memory address ranges. Determining how to set switches for (or configuring) these resources can be complex. Plug and Play adapters and devices make this task easier. Plug and Play Adapters Plug and Play adapters are easier to install and set up because they are auto-configuring (no jumpers or switches) to set. A Plug and Play adapter comes with built-in identification and configuration specifications set in the adapter memory. This information is sensed by the I/O bus and interpreted by the computer BIOS. The BIOS routines then automatically configure the adapter around the resources already in use by other devices. 220 IBM PC 300/700, IntelliStation Series HMM
