#so include your on-board display in the count if it is enabled.
#-You can run your favorite miner if number matches
#-Shutdown computer with a delay if the number doesn't match
#-or you may still choose to run the miner with an alternative safe configuration
#-Due to separation of concerns, I have separate batches for notification and they are disabled here.
