| .I device |
| is usually one of the following (for floppy devices the major = 2, and the |
| minor is shown for informational purposes only): |
| .sp |
| .nf |
| .RS |
| /dev/fd0d360 (minor = 4) |
| /dev/fd0h1200 (minor = 8) |
| /dev/fd0D360 (minor = 12) |
| /dev/fd0H360 (minor = 12) |
| /dev/fd0D720 (minor = 16) |
| /dev/fd0H720 (minor = 16) |
| /dev/fd0h360 (minor = 20) |
| /dev/fd0h720 (minor = 24) |
| /dev/fd0H1440 (minor = 28) |

| .PP |
| The generic floppy devices, /dev/fd0 and /dev/fd1, will fail to work with |
| .B fdformat |
| when a non-standard format is being used, or if the format has not been |
| autodetected earlier. In this case, use |
| .BR setfdprm (8) |
| to load the disk parameters. |
