The other thing you might want to check out is if you multiboot your laptop that any non-FreeBSD operating system may put hardware into an inconsistent state. For example, my Acer laptop loses sound if I boot Windows then boot FreeBSD. The workaround is either adjust the HDA inputs/outputs through sysctl or simply power cycle the laptop. -- Cheers, Cy Schubert FreeBSD UNIX: Web: http://www.FreeBSD.org The need of the many outweighs the greed of the few.
