Test Descriptions
System Test Menu
The tests included in the System Test Menu exercise the basic functionality of the CPU, ensuring that the
registers, the flags, and both the basic and protected instructions work as expected. It includes tests of the
chip speed as well as the operation of integrated controllers for coprocessing, DMA, interrupts, and the
timers and clock functionality. Specialized tests for PCI devices, Plug and Play devices, and MMX
instructions are also included.
Basic Functionality Test
This test checks the 32-bit registers, 32 bit flags, and specific processor instructions.
CPU Protected Mode Test
This test checks if all protected mode special instructions are working properly.
Processor Speed Test
This test determines and displays the CPU clock speed. If you provide a specific clock speed to compare it
with, this test will report error if the expected speed and detected speed does not match.
Coprocessor Test
The tests include loading and storing the control and status word, data transfer between CPU and NPX, and
exception checking while the data transfer is in progress.
DMA Controller Test
The DMA Controller Test is a series of read/write tests on the memory address and page registers of DMA
controllers 1 and 2.
Interrupt Controller Test
This test performs a series of read/write tests on interrupt mask registers of the interrupt controller. It also
checks for stray interrupts.
Timer Test
This test checks the accuracy of the timer count by calibrating it against the periodic interrupt of the real
time clock (RTC).
Real Time Clock Test
This test checks the accuracy of the real time clock by calibrating it against the system timer. It also does a
pattern test on RTC.
CMOS Validity Test
This test checks the condition of AT CMOS RAM (non-volatile memory). The test assures that the CMOS
battery is in good condition and that the CMOS RAM checksum is correct.
Speaker
This tests checks the functionality of your Speaker by playing a short song.
