Floppy disk detection
|
|
---------------------
|
|
|
|
86Box detects the physical media format (sides, tracks per side, sectors per track, bytes per sector) of a floppy disk image through the following methods:
|
|
|
|
1. Data stored in the file header, except for Raw and DiskDupe formats where there is none.
|
|
2. Data stored in the `DOS BIOS Parameter Block <https://en.wikipedia.org/wiki/BIOS_parameter_block>`_.
|
|
3. If all else fails, a guess is made based on the file size.
|
|
|
|
The BIOS Parameter Block detection may result in incorrect behavior on *raw stream* (non-DOS) floppy disks. Installation floppies for UNIX and Linux are common examples of *raw stream* disks. Disabling the :ref:`settings/floppycdrom:Check BPB` option is strongly recommended for accessing these, as the inaccurate BPB detection may result in read errors, data corruption and other issues.
|
|
|
|
.. note:: When using a raw image of a raw stream floppy with the Check BPB option disabled, make sure the image file has the right size for its media type, otherwise incorrect behavior may still occur. |
