+Module Name:
+
+ Partition.h
+
+Abstract:
+
+ Partition driver that produces logical BlockIo devices from a physical
+ BlockIo device. The logical BlockIo devices are based on the format
+ of the raw block devices media. Currently "El Torito CD-ROM", Legacy
+ MBR, and GPT partition schemes are supported.
