They ban your bios because most isp's do not provide a static ip they use the dynamic ip system. So everytime you log into xbl it could be with a differant ip so banning a single ip would not be effective.
I know for a fact that a banned xbl chipped xbox can be fixed by flashing the bios with a new one.
