PS: I managed to get audible POST signals by using a selected buzzer, but a sleep 15; printf "\a"; printf "\a"; printf "\a";printf "\a"; printf "\a"; p= rintf "\a";printf "\a"; printf "\a"; printf "\a";printf "\a"; printf "\a"; = printf "\a" is barely audible. "sleep 15" because pushing the enter-key is way, way lou= der than the "click" produced by printf "\a".
