Writing disks
-------------
@@ -23,51 +24,39 @@ FluxEngine can also write Atari ST scheme disks.
The syntax is:
fluxengine write atarist -i input.st <options>
fluxengine write ibm -i input.st <options>
The format of `input.st` will vary depending on the kind of disk you're writing,
which is configured by the options. By default FluxEngine will write an 80
track, 9 sector, double-sided disk. If that doesn't match your target format you
will need to pass some options. There are some presets, which you will almost
certainly want to use if possible:
The format of `input.st` will vary depending on the kind of disk you're
writing, which is configured by the options. You will almost certainly need to
pass one of these:
- `--st-preset-360`: a 360kB 3.5" disk, with 80 cylinders,
1 side, and 9 sectors per track.
- `--st-preset-370`: a 370kB 3.5" disk, with 82 cylinders,
1 side, and 9 sectors per track.
- `--st-preset-400`: a 400kB 3.5" disk, with 80 cylinders,
1 side, and 10 sectors per track.
- `--st-preset-410`: a 410kB 3.5" disk, with 82 cylinders,
1 side, and 10 sectors per track.
- `--st-preset-720`: a 720kB 3.5" disk, with 80 cylinders,
2 sides, and 9 sectors per track.
- `--st-preset-740`: a 740kB 3.5" disk, with 82 cylinders,
2 sides, and 9 sectors per track.
- `--st-preset-800`: a 800kB 3.5" disk, with 80 cylinders,
2 sides, and 10 sectors per track.
- `--st-preset-820`: a 820kB 3.5" disk, with 82 cylinders,
2 sides, and 10 sectors per track.
- `--ibm-preset-atarist-360`: a 360kB 3.5" disk, with 80 cylinders, 1 side,
and 9 sectors per track.
- `--ibm-preset-atarist-370`: a 370kB 3.5" disk, with 82 cylinders, 1 side,
and 9 sectors per track.
- `--ibm-preset-atarist-400`: a 400kB 3.5" disk, with 80 cylinders, 1 side,
and 10 sectors per track.
- `--ibm-preset-atarist-410`: a 410kB 3.5" disk, with 82 cylinders, 1 side,
and 10 sectors per track.
- `--ibm-preset-atarist-720`: a 720kB 3.5" disk, with 80 cylinders, 2 sides,
and 9 sectors per track.
- `--ibm-preset-atarist-740`: a 740kB 3.5" disk, with 82 cylinders, 2 sides,
and 9 sectors per track.
- `--ibm-preset-atarist-800`: a 800kB 3.5" disk, with 80 cylinders, 2 sides,
and 10 sectors per track.
- `--ibm-preset-atarist-820`: a 820kB 3.5" disk, with 82 cylinders, 2 sides,
and 10 sectors per track.
These options simply preset the output destination flag (`-d`) and the
following, lower-level options. Note that options are processed left to right,
so it's possible to use a preset and then change some settings. To see the
values for a preset, simply append `--help`.
- `--st-sector-size=N`: the size of a sector, in bytes. Must be a power of
two.
- `--st-gap1-bytes=N`: the size of gap 1 in bytes (between the IAM record
and the first sector record).
- `--st-gap2-bytes=N`: the size of gap 2 in bytes (between each sector
record and the data record).
- `--st-gap3-bytes=N`: the size of gap 3 in bytes (between the data record
and the next sector record).
- `--st-sector-skew=0123...`: a string representing the order in which to
write sectors: each character represents on sector, with `0` being the
first. Sectors 10 and above are represented as letters from `A` up.
See [the IBM format documentation](disk-ibm.md) for more information.
