Thank you. I should have to search archives, it would solve my crazy headaches :) Anyway, it's surprise that after fans replug to different connectors on the board - which has caused OpenBSD not detecting one fan - the board doesn't beep anymore. So yes, it must be related to the issue you pointed to. Jiri
