Currently the tools only support sector sizes of 256 bytes. It is
unknown what will happen if you try a different size sector sizes.

    For all the time I used OS9/6809, I never ran accros a sector
    size other than 256 bytes.
    The big issue was different disk formats.
    96 TPI vs 48 TPI. 16 sectors / track vs 18 (coco) sectors/track
    Dbld sided vs single sided. Dbl vs single density.
    And most severe problem What format was Sector 0, Track0
    Std: always single density, 16 sectors/track.
    Coco: DSDD 18 sectors/track.

    Os9/6809 had many assumptions about 256 byte structures
    built in to it, including almost all of the memory management
    routines.
