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 diag-
nostics. 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 com-
ponents, such as the speaker, that are not tested elsewhere in the diagnostics.
The following symptoms usually suggest a problem with a component or sub-
assembly that warrants running a System Set subtest:
A program is not running as usual, or a proven piece of software appears to mal-
function 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 abnor-
mally 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.)
