Coprocessor Calculation Test Checks the use of different types of numbers and the math coprocessor's ability to calculate correctly. Coprocessor Error Exception Test Verifies the math coprocessor's ability to handle errors and to send IRQs to the microprocessor. Multiprocessor Test For systems with multiprocessors, confirms that the secondary microprocessor is operational. The System Set subtests double-check many system board components, such as the computer's I/O circuitry, that are tested by other test groups or subtests in the diagnostics. You should run the System Set test group if you are having a problem and cannot isolate the failure or malfunction to a particular system board component. The System Set test group also verifies the proper operation of other computer components, such as the speaker, that are not tested elsewhere in the diagnostics. The following symptoms usually suggest a problem with a component or subassembly that warrants running a System Set subtest: A program is not running as usual, or a proven piece of software appears to malfunction and you confirm that the software itself is not at fault. (You can confirm that the software is functioning properly by moving it to another computer and running it there.) An option card you previously accessed can no longer be accessed. You get a parity error or page fault failure-any error message that contains the word[s] parity or page fault-at any time during operation. These errors are usually accompanied by a reference to an address, which you should record on a copy of the Diagnostics Checklist found in Chapter 11, "Getting Help." Correcting errors in the system configuration information in the System Setup program does not resolve a problem. The computer's clock/calendar stops. The speaker no longer functions. The problem could be a failure of the system timers as well as a failure of the speaker itself. Run the System Timers test, followed by the System Speaker test. A peripheral device appears to malfunction. Run the Interrupt Controllers test. A spreadsheet program or other type of mathematical application runs abnormally slow, generates error messages concerning calculations or operations, runs incorrectly, or generates incorrect results, or a proven piece of the program appears to malfunction and you confirm that the software itself is not at fault. (You can confirm that the software is not at fault by moving the program to another computer and running it there.) Running the Dell Diagnostics 5-15
