Netfinity 3000 - Configuration Conflicts

Applicable to: World-Wide

Configuration Conflicts
The resources used by your server consist of IRQs, DMA, I/O port addresses, and memory. This information is
useful when a resource configuration conflict occurs.

Conflicts in the configuration occur if:

- A device that you installed requires the same resource as another device. (For example, a conflict occurs when two adapters try to write to the same address space.)
- A device resource is changed (for example, changing jumper settings).
- A device function is changed (for example, assigning COM1 to two serial ports).
- A software program is installed that requires the same resource as a hardware device.

The steps required to resolve a configuration error are determined by the number and variety of hardware devices
and software programs that you install. If a hardware configuration error is detected, a configuration error message appears after the server completes POST and before the operating system is loaded. You can bypass the error by pressing Esc while the error message is displayed.

The Configuration/Setup Utility program configures only the system hardware and interrupt requests. The program
does not consider the requirements of the operating system or the application programs. For these reasons,
memory-address configuration conflicts might occur. You can resolve some memory-address conflicts by changing
the address of the conflicting hardware option, or by changing or moving the hardware. You might have to
resolve other memory-address conflicts by changing some software parameters. See Hardware Configuration
Conflicts and Software Configuration Conflicts on page 21, respectively, for additional information.

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 "Configuration/Setup Utility Program" 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. 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 ISA and PCI Adapters".

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.

Note Start the Configuration/Setup Utility program to view the addresses that are used by your system board functions.

The best way to resolve memory-address conflicts is to change the addresses that are used by the application
program or the device driver. You can use the Configuration/Setup Utility program to view and change addresses.

Configuration/Setup Utility Program

For most configurations, the server will operate using the default system settings. You need to change the settings
only to resolve configuration conflicts or to enable or change device functions.

When you want or need to change the default settings, the Configuration/Setup Utility program provides a convenient way to display and change the settings.

After you run and exit the Configuration/Setup Utility program, configuration information is stored in electrically
erasable programmable read-only memory (EEPROM). While the server is powered off, the configuration
information remains available for the next system startup.

Always run the Configuration/Setup Utility program if you receive an error message instructing you to do so. If you
installed or removed SCSI devices, run the SCSISelect Utility program (see "SCSISelect Utility Program"). Review the information that comes with the option before making changes.

When you restart the server for the first time after working with most options, a message appears, indicating that a
configuration change has occurred. You are then prompted to enter the Configuration/Setup Utility program to manually update the configuration settings or to confirm and save the settings that were automatically updated by
the system programs.

After you change an option and restart the server, the following screen might appear.

Note Depending on the configuration changes that occurred, the error message that you see might be different from the one shown here.

If the preceding screen appears, select Continue until you reach the Configuration/Setup Utility program menu; then,
go to "Configuration/Setup Utility Program Menus".

If the preceding screen does not appear, use the following procedures to access the Configuration/Setup Utility
program menu.

To start the Configuration/Setup Utility program:

1. Power-on the server and watch the screen.

If the server is already turned on, power-off the server, wait a few seconds until all in-use lights go off, and then power the server back on. (Do not use Ctrl+Alt+Del to restart the server.)

2. When the message "Press F1 to enter Configuration/Setup" appears, press F1. The Configuration/Setup Utility program menu appears. For information about the menus, see "Configuration/Setup Utility Program Menus".

Notes 1. If an administrator password is not set, the Configuration/Setup Utility program starts once you complete the startup procedure. 2. If an administrator password is set, but a power-on password is not set, you must enter the administrator password to access the Configuration/Setup Utility program. 3. If you have set both an administrator and a power-on password, you can enter either one. However, to change any settings in the Configuration/Setup Utility program, you must enter the administrator password. If you enter the power-on password, you can view limited information in the Configuration/Setup Utility program, but you cannot change any settings. 4. If a configuration error occurs, a prompt appears before the operating system starts ( see "Configuration Conflicts".)
