The currentBIOS setup pictures in the chapter are for reference only, which may change by the BIOSmodification in the future. If any unclear message occurs, please contactDELTA COMPONENTS GmbH customer service representative for help.4.1 About the BIOSThe BIOS (Basic Input and Output System) Setup program is a menu driven utility thatenables you to make changes to the system configuration and tailor your system to suit yourindividual work needs. It is a ROM-based configuration utility that displays the system’sconfiguration status and provides you with a tool to set system parameters. These parametersare stored in non-volatile battery-backed-up CMOS RAM that saves this information evenwhen the power is turned off. When the system is turned back on, the system is configuredwith the values found in CMOS.With easy-to-use pull down menus, you can configure such items as:♦ Hard drives, diskette drives, and peripherals♦ Video display type and display options♦ Password protection from unauthorized use♦ Power management featuresThe settings made in the Setup program intimately affect how the computer performs. It isimportant, therefore, first to try to understand all the Setup options, and second, to makesettings appropriate for the way you use the computer.4.2 When to Run BIOSThis program should be executed under the following conditions:♦ When changing the system configuration♦ When a configuration error is detected by the system and you are prompted to makechanges to the Setup program♦ When resetting the system clock♦ When redefining the communication ports to prevent any conflicts♦ When making changes to the Power Management configuration♦ When changing the password or making other changes to the security setupNormally, CMOS setup is needed when the system hardware is not consistent with theinformation contained in the CMOS RAM, whenever the CMOS RAM has lost power, or thesystem features need to be changed.
