    fdisk - Use heads = 255 on file images
    
    When operating on a file image use max values for sectors and heads in
    order to match the case where the file might exceed the CHS limit.  By
    convention the CHS fields are set to all 1's in this case.
    
    If our sectors and heads are not set at max values then the all 1's case
    will result in a geometry that overflows the originally specified sectors
    and heads which can brick the BIOS.
