Display codes when the operating system comes to an abnormal end.

During POST, the numbers that are displayed indicate the progress of the testing. If an error
is detected that requires attention, the system unit halts and a number is displayed in the
three-digit display to identify the error.
For instance, if the number for the error were 888, the three-digit display would appear as
shown in the following figure.
