+// |  with an End Entire Device Path sub-type)             |
+// +-------------------------------------------------------+
+//
+// If there are n (n > 1) storage devices in the list, the content of this
+// LockBox will be:

+// +-------------------------------------------------------+
+// |                 DevPath Instance #1                   |
