The EASIEST way to identify what's in the MBR or VBR is to run `ms-sys` with no other arguments than
the device:

        % ms-sys /dev/sda1
        /dev/sda1 has a FAT32 file system.
        /dev/sda1 has an x86 boot sector,
        it is exactly the kind of FAT32 DOS boot record this program
        would create with the switch -3 on a FAT32 partition.
