attempting to display the error. Beep codes are useful for identifying the
error when the system is unable to display the error message.

Lights on the Status Panel

When the computer is first powered on, the power-on light on the status
panel illuminates yellow for about a second before changing to green. This
change of color is caused by the execution of an instruction early in the
System BIOS code.
If the light remains at yellow, therefore, it indicates a failure of the processor
or the System ROM in the instruction-fetch process. Check that the
processor is correctly seated in its socket.
