The QNX Neutrino RTOS complies with the de facto industry standard for partitioning a disk.
This allows a number of filesystems to share the same physical disk. Each partition is also represented as a block-special file, with the partition type appended to the filename of the disk it's located on. In the above two-disk example, if the first disk had a Power-Safe partition and a DOS partition, while the second disk had only a Power-Safe partition, then the default files would be:
The following list shows some typical assigned partition types:
Type | Filesystem |
---|---|
1 | DOS (12-bit FAT) |
4 | DOS (16-bit FAT; partitions <32M) |
5 | DOS Extended Partition (enumerated but not presented) |
6 | DOS 4.0 (16-bit FAT; partitions ≥32M) |
7 | OS/2 HPFS |
7 | Windows NT |
11 | DOS 32-bit FAT; partitions up to 2047G |
12 | Same as Type 11, but uses Logical Block Address Int 13h extensions |
14 | Same as Type 6, but uses Logical Block Address Int 13h extensions |
15 | Same as Type 5, but uses Logical Block Address Int 13h extensions |
