| 16 | Abstract:\r |
| 17 | \r |
| 18 | Partition driver that produces logical BlockIo devices from a physical \r |
| 19 | BlockIo device. The logical BlockIo devices are based on the format\r |
| 20 | of the raw block devices media. Currently "El Torito CD-ROM", Legacy \r |
| 21 | MBR, and GPT partition schemes are supported.\r |
