ae c7b111bbcf MS Windows NT+ uses 4 bytes at offset 0x1b8 in the MBR to identify
disk drive. The boot0cfg(8) utility preserves these 4 bytes when is
writing bootcode to keep a multiboot ability.
Change gpart's bootcode method to keep DSN if it is not zero. Also
do not allow writing bootcode with size not equal to MBRSIZE.
