      6 // The magic is the build date YYMMDD encoded as BCD in 3 bytes,
      7 // thus installing firmware built on a different date to the one
      8 // already installed can be detected and the EEPROM data is reset.
      9 // The only reason this is important is in case EEPROM usage changes
     10 // and the EEPROM was not explicitly reset by bootmagic lite.
