+         Adds support for the Intel Volume Management Device (VMD). VMD is a
+         secondary PCI host bridge that allows PCI Express root ports,
+         and devices attached to them, to be removed from the default
+         PCI domain and placed within the VMD domain. This provides
+         more bus resources than are otherwise possible with a
+         single domain. If you know your system provides one of these and
+         has devices attached to it, say Y; if you are not sure, say N.
