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 non-DOS-compatible floppy disks. Installation floppies for UNIX and Linux are common examples of non-DOS-compatible disks. Disabling the :ref:`Check BPB <settings/floppycdrom:Floppy drives>` setting 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 non-DOS-compatible floppy with the Check BPB setting disabled, make sure the image file has the right size for its media type, otherwise incorrect behavior may still occur.

CD audio
|
|
^^^^^^^^
|
|
|
|
Compact Disc Digital Audio (CDDA) is supported on *Cue sheet* images. CD audio playback is muted on all drives by default; it can be unmuted by unchecking the *Mute* option for the respective CD |nbdash| ROM drive on the status bar or the Media menu.
|
|
|
|
.. note:: Only raw format (.bin) tracks are supported. Compressed or otherwise encapsulated audio tracks (.wav, .mp3, .ogg, .flac and other formats) are not supported.
