Interrupt Controller Test
Generates an interrupt on each interrupt request (IRQ) line to verify that devices using that line
can communicate with the microprocessor and that the interrupt controllers send the correct
memory addresses to the microprocessor.
Reset Button Test
Confirms that the reset button works.
System Speaker Test
Checks the functionality of the speaker by generating eight tones.
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.
PC Card Controller Test
Tests the functionality of the PC Card controller on the system board.
Thermal Control Test
Checks the functionality of the thermal-monitoring and microprocessor speed-switching device on
the system board.
Multiprocessor Test
For systems with multiprocessors, confirms that the secondary microprocessor is operational.
USB Register Test
Checks the onboard registers of the Universal Serial Bus (USB) interface. This subtest does not
test USB peripherals.
USB Memory Structure Test
Monitors the ability of a USB controller to process a simple set of memory-resident instructions.
Why Run a System Set Test?
The System Set subtests double-check many system board components, such as the computer’s
input/output (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 Dell Diagnostics.
