      Low Level Format can be done on boards that have their BIOS enabled  
      by utilizing the DOS DEBUG command g=cc00:5.                         
                                                                           
      It is recommended that a Format be accomplished when changing from a 
      WD1003-XXX controller to the WD1006V type controller.
