thanks for the answers fellas.
But the funny thing is your answers are for someone who doesn't know anything about electronics and/or computers but fortunately I am doing my phd in nanoelectronics. So I know that aside from manufacturer specific tools, there are tons of 3rd party tools that can control the motherboard signals such as setFSB, clockgen and etc. in windows. However FreeBSD or linux/unix systems in general don't seem to have such support within the kernel to provide access to these signals. I am an experienced overclocker however not so experienced FreeBSD user as I switched back to it again after 5 years and I wanna give play around with the hardware parameters.
Can anyone at least give me a direction other than simple answers or let the more experienced people answer.
cheers
