I have a server (standard ATX motherboard) that tends to lock up, and I'd like to reset it using the Raspi. I know the motherboard has a reset switch/jumper, but I don't know what voltage it outputs to detect when it's closed. Does anyone have any experience doing something like this? It seems like GPIO 18 could pull the line high and perform the reset, but I don't want to fry a pin or the board if I can help it.
Thanks!
