The Configuration/Setup Utility program configures the system hardware and PCIIRQs. The program does not consider the requirements of the operating system orthe application programs. See “Resolving software configuration conflicts” onpage 31 for additional information.Resolving hardware configuration conflictsUse the following information to help resolve hardware configuration conflicts:1. Run the Configuration/Setup Utility program to view and change resourcesused by the system functions and the installed options. Record the currentsettings before making any changes. (See “The Configuration/Setup Utilityprogram” on page 20 for instructions.)2. Determine which adapter or device is causing the conflict. (See Chapter 6,“Solving problems” for instructions.)3. Change adapter jumpers or switches. Some devices use jumpers and switchesto define the system resources that the devices need. If the settings areincorrect or set to use a resource that cannot be shared, a conflict occurs andthe device will remain deactivated by the configuration program.4. Change system jumpers or switches. See “Changing jumper positions” onpage 103.5. Remove the device or adapter. Some configurations are not supported. If youmust remove an adapter, see “Working with adapters” on page 53.Resolving software configuration conflictsThe memory-address space and IRQs used by some hardware options mightconflict with addresses defined for use through application programs or theexpanded memory specification (EMS). (EMS is used only with DOS.)If a conflict exists, one or more of the following conditions might exist: The system cannot load the operating system. The system does not work. An application program does not operate, or it returns an error. Screen messages indicate that a conflict exists.To resolve conflicts, you can change the software or hardware configuration.Note: Start the Configuration/Setup Utility program to view the addresses used byyour server functions. (See “The Configuration/Setup Utility program” onpage 20 for instructions.)The best way to resolve memory-address conflicts is to change the addresses usedby the application program or the device driver. You can use theConfiguration/Setup Utility program to change addresses.If a device driver is causing a memory-address conflict, refer to youroperating-system documentation or the documentation that comes with the devicedrivers.Chapter 3.
