Today it only beeped at me while running Director - not in the finder. It's not the SuperClock chime; I've turned SC off. I assume simms with 9 chips have parity. If that's the case, I replaced the parity chips with non-, and still got the dialog on startup and still got the beeps. I'm completely stymied, and need an answer by Thursday. Again, thanks for all help. ken mohnkern # the graphics deli # the robotics institute # pittsburgh pa
