   Yes, it is really the lowest level possible for programming.   
   But it can also be a life saver for complete sector restore.   
   (you need to know and be aware of CHS and LBA formats)   
      
   I wrote my whole OS [KESYS] in hexadecimal and ASCII only.   
   But my own tool gave me much more comfort than DOS-debug:   
   * immediate disassemble for input verify   
   * allow full navigation within set limits (ie: go back up).   
   * can change between 16/32/64bit code interpreter anytime.   
   * toggle between ASCII/HEX input and dump view as well.   
   * RD/WR from/to any media, incl. partial sector writes.   
   * and a few more :)   
      
   unfortunately it became all history now (damned UEFI)
