Back to Contents PageFinding Software SolutionsDell™ PowerEdge™ 6600 Systems Installation and Troubleshooting GuideInstalling and Configuring SoftwareUsing SoftwareBecause most systems have several application programs installed in addition to the operating system, isolating a software problem can be confusing.Software errors can also appear to be hardware malfunctions at first.Software problems can result from the following circumstances:l Improper installation or configuration of a programl Input errorsl Device drivers that may conflict with certain application programsl Interrupt conflicts between devicesYou can confirm that a system problem is caused by software by running the system diagnostics. If all tests in the test group are completed successfully, theproblem is most likely caused by software.This section provides some general guidelines for analyzing software problems. For detailed troubleshooting information on a particular program, see thedocumentation that accompanied the software or consult the support service for the software.Installing and Configuring SoftwareUse virus-scanning software to check newly acquired programs and files for viruses before installing the programs on the system's hard drive. Viruses canquickly use all available system memory, damage or destroy data stored on the hard drive, and permanently affect the performance of the programs theyinfect. Several commercial virus-scanning programs are available for purchase.Before installing a program, read its documentation to learn how the program works, what hardware it requires, and what its defaults are. A program usuallyincludes installation instructions in its accompanying documentation and a software installation routine.The software installation routine assists users in transferring the appropriate program files to the system's hard drive. Installation instructions may providedetails about how to configure the operating system to successfully run the program. Always read the installation instructions before running a program'sinstallation routine.When you run the installation routine, be prepared to respond to prompts for information about how the system's operating system is configured, what typeof system you have, and what peripherals are connected to the system.Using SoftwareThe following subsections discuss errors that can occur as a result of software operation or configuration.Error MessagesError messages can be produced by an application program, the operating system, or the system. "Indicators, Messages, and Codes" discusses the errormessages that are generated by the system. If you receive an error message that is not listed in "Indicators, Messages, and Codes," check the operatingsystem or application program documentation.Input ErrorsIf a specific key or set of keys is pressed at the wrong time, a program may give you unexpected results. See the documentation that came with theapplication program to make sure that the values or characters you are entering are valid.Make sure that the operating environment is set up to accommodate the programs you use. Keep in mind that whenever you change the parameters of thesystem's operating environment, you may affect the successful operation of the programs. Sometimes, after modifying the operating environment, you mayneed to reinstall a program that no longer runs properly.Program ConflictsSome programs may leave portions of their setup information behind, even though you have exited from them. As a result, other programs cannot run.Rebooting the system can confirm whether these programs are the cause of the problem.Device drivers, which are programs that use specialized subroutines, can cause problems with the system. For example, a variation in the way the data is sentto the monitor may require a special screen driver program that expects a certain kind of video mode or monitor. In such cases, you may have to develop analternate method of running that particular program—by creating a start-up file made especially for that program, for example. Contact the support service forthe software you are using to help you with this problem.Avoiding Interrupt Assignment ConflictsMost PCI devices can share an IRQ line with another device. However, no two devices can use the IRQ line simultaneously. Problems can arise if a PCI devicecannot share an IRQ line or if two devices attempt to use the same IRQ line simultaneously. To avoid this type of conflict, see the documentation for eachinstalled expansion card. Consult Table 3-1 to configure the card for one of the available IRQ lines.
