It is the same as D-LED that has 4 LEDs that light in certain orders to give you differant error codes. There is even a board that has a voice chip that will speak the problem in English (and at least one other language). A neat feature, that can save a bit of time if say the contacts on your DIMMs were not very clean or the keyboard was not plugged in all the way...
The COMPUTER is your FRIEND!
Happiness is manditory.
