273	  secondary PCI host bridge that allows PCI Express root ports,
274	  and devices attached to them, to be removed from the default
275	  PCI domain and placed within the VMD domain. This provides
276	  more bus resources than are otherwise possible with a
277	  single domain. If you know your system provides one of these and
278	  has devices attached to it, say Y; if you are not sure, say N.
279
280	  To compile this driver as a module, choose M here: the
281	  module will be called vmd.
