Displays the contents of the default or of the specified sector
    as a Master Boot Record (MBR) structure.

                                   NOTE

       The FAT partition typically mounted with this utility
       does not include a Master Boot Record (MBR) structure. An
       entire OpenVMS I64 system disk will include a Legacy or a
       Protective MBR, however. To display the contents of the
       disk-level bootblock structures, please see the SYS$SETBOOT
       foreign-command interface.
