The subtests in the System Set Test Group check the computer's basic system board components and verify their related functions. The subtests that constitute the System Set Test Group and the computer functions they confirm follow: CMOS Confidence Test Checks the NVRAM for accessibility and reliability of data storage by performing a data pattern check and verifying the uniqueness of memory addresses. DMA Controller Test Tests the direct memory access (DMA) controller and verifies the correct operation of its page and channel registers by writing patterns to the registers. Real-Time Clock Test Confirms the functionality and accuracy of the computer's real-time clock (RTC). System Timers Test Checks the timers used by the microprocessor for event counting, frequency generation, and other functions. Only the functions that can be activated by software are tested. 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. APIC Test Tests that the procedure used to boot a multiprocessor system is able to properly receive interrupts from the input/output (I/O) Advanced Peripheral Interrupt Controller (APIC). APIC MP Test Ensures that all microprocessors are able to properly receive interrupts from the I/O APIC. 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. 5-14 Dell PowerEdge 2300 Systems Installation and Troubleshooting Guide
