/*
* 86Box A hypervisor and IBM PC system emulator that specializes in
* running old operating systems and software designed for IBM
* PC systems and compatibles from 1981 through fairly recent
* system designs based on the PCI bus.
*
* This file is part of the 86Box distribution.
*
* Implementation of the 86F floppy image format (stores the
* data in the form of FM/MFM-encoded transitions) which also
* forms the core of the emulator's floppy disk emulation.
