[Brent Bailey]

because no one answers..thats why i keep posting it ..and when i look at
the freebsd handbook on how to do this ...it reads in a very general
way..like stereo instructions. Alos i cant afford to mess up the systems
im trying to do this on...so i just want to be sure... sorry for asking
this
