      F:\Flash.BAT
      F:\CONFIG.SYS
      F:\HIMEM.SYS
      F:\EMM386.EXE
      F:\SSDflash.EXE
      F:\1.BIN
      F:\SSDC.DAT
      ....etc
      
3. Boot to MSDOS by USB bootable device

4. Select menu :  [NORMAL, MSDOS + himem.sys]
   
5. Execute Flash.BAT to update firmware
   
Note: 
    For some specific platforms, if [NORMAL, MSDOS + himem.sys] is not work;
    Please reboot the system, select [EMM386, MSDOS + himem.sys + emm386.exe] instead.
