Error messages are generated by system hardware or software. "Indicators, Codes, and Messages"
provides information about error messages that are hardware-based. If you receive an error message
that is not listed, see your operating system or software program documentation for
troubleshooting information.
Input Errors
Pressing a specific key or set of keys at the wrong time may produce unexpected results. See the
documentation that came with the software application to ensure that the values or characters you
are entering are valid.
Ensure that your operating system is configured properly to run the application. Remember that
whenever you change the parameters of the operating system, the changes can conflict with an
application’s operating requirements. After you configure the operating system, you may need to
reinstall or reconfigure a software application so that it can run properly in its new environment.
Application Conflicts
Some applications can leave unnecessary files or data behind after they are deleted from your
system. Device drivers can also create application errors. If application errors occur, see your
application device driver or operating system documentation for troubleshooting information.
IRQ Assignment Conflicts
Most PCI devices can share an IRQ with another device, but they cannot use an IRQ
simultaneously. To avoid this type of conflict, see the documentation for each PCI device for
specific IRQ requirements.
