Resolving Configuration Conflicts Resolving Hardware Configuration Conflicts Use the following information to help resolve hardware configuration conflicts: 1. Run the Configuration/Setup Utility program to view and change the resources that the system board functions use. Record the current settings before making any changes. (See "The Configuration/Setup Program" on page 26 for instructions.) 2. Determine which adapter or device is causing the conflict. 3. Change adapter jumpers or switches. Some devices use jumpers and switches to define the system resources that they need. If the settings are incorrect or set to use a resource that cannot be shared, a conflict occurs, and the device will remain deactivated by the configuration program. 4. Change system board jumpers or switches. See "Preparing to Add Options" on page 56 for instructions for removing the cover. Then, refer to the system-board diagram inside your server. 5. Remove the device or adapter. Some configurations are not supported. If you must remove an adapter, see "Installing or Removing Adapters" on page 61. Resolving Software Configuration Conflicts The Configuration/Setup utility might change the memory-address space used by some hardware options. If this happens, the new memory-address space and IRQs used by some hardware options might conflict with addresses defined for use through application programs. 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 memory-address conflict exists. Chapter 3. Configuring Your Server 43
