Diagnostic programs
The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the system board. These programs are the primary method of testing the major
components of your server, such as the the system board, Ethernet controller,
video controller, RAM, keyboard, mouse (pointing device), diskette drive, serial port,
and parallel port. You can also use them to test some external devices.

the software, you can run the diagnostic programs to confirm that the hardware is
working properly.
