A system having a processor, a printed circuit board, and an adapter board, coupled to the processor through the printed circuit board. The adapter board provides a first signal having a first state when the adapter board is in a proper operating condition and a second state when the adapter board is in an improper condition. The adapter board produces a second signal having the second state for less than a predetermined time when an adapter board requires a reset signal from the processor. The adapter board combines the first signal with the second signal a single signal fed to the processor through the printed circuit board. When the processor detects that the single signal is in the second state for a time less than the predetermined period of time, the process interprets the single signal as indicating the adapter board requires a reset.
