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.
