It shows self-test codes and power supply status when power is switched on. You will see what"s wrong with a system that won"t boot,
even if the screen is blank! Just plug the card in an ISA or PCI slot, switch on power, and watch the digital display. If a failure is detected by the system self-test, it will halt, and the failing test number will be on the LED display.
