Floppy disk detection
|
|
^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
86Box determines the physical media format (sides, tracks per side, sectors per track, bytes per sector) of a floppy disk image through the following methods:
|
|
|
|
1. Image file header data - not applicable for **Raw** and **DiskDupe** formats;
|
|
2. `DOS BIOS Parameter Block <https://en.wikipedia.org/wiki/BIOS_parameter_block>`_ data within the image;
|
|
3. If all else fails, a guess is made based on the image file's size.
|
|
|
|
The BIOS Parameter Block detection method may behave incorrectly with non-DOS floppy disks. Installation floppies for UNIX and Linux are common examples of non-DOS disks. Disabling :ref:`Check BPB <settings/floppycdrom:Floppy drives>` is strongly recommended for accessing these, as an inaccurate BPB detection may result in read errors, data corruption and other issues.
|
|
|
|
.. note:: When using a **Raw** image of a non-DOS floppy with Check BPB disabled, make sure the image file is not truncated (smaller than its media size), 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 emulated CD-ROM drives by default; it can be unmuted by unchecking the *Mute* option for the respective drive on the :ref:`status bar <usage/statusbar:|cdrom| |nbsp| CD-ROM drives>` or the :ref:`Media menu <usage/menubar:Media>`.
|
|
|
|
.. note:: Only raw format (.bin) tracks are supported. Compressed or otherwise encapsulated audio tracks (.wav, .mp3, .ogg, .flac and other formats) are not supported.
