| 2 | Partition driver that produces logical BlockIo devices from a physical \r | |
| 3 | BlockIo device. The logical BlockIo devices are based on the format\r | |
| 8aafec2c | 4 | of the raw block devices media. Currently "El Torito CD-ROM", UDF, Legacy\r |
| adbcbf8f | 5 | MBR, and GPT partition schemes are supported.\r |
