 272           Adds support for the Intel Volume Management Device (VMD). VMD is a
 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.
