Beep Codes

If a terminal error occurs during POST, the system issues a beep code before attempting to display the error. Beep codes are useful for identifying the error when the system is unable to display the error message.

				system startup.

Lights on the Status Panel

When the computer is first powered on, the power-onlight 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, and that its VRM is also correctly seated.
