6.2 Using SMARTDrive with Double Buffering

   Most  expanded-memory   emulators  attempt   to  optimize   SMARTDrive  by
   configuring it to  load into upper  memory blocks (UMBs).  This will cause
   problems if  you are  running Windows  in  386 enhanced  mode  with double
   buffering. If you need to use  double buffering with SMARTDrive, make sure
   that SMARTDrive  is configured  in the  CONFIG.SYS file  to load  into low
   memory. The command line should look like this:

     device=smartdrv.exe /double_buffer

   This problem applies only  to the smartdrv command  line in the CONFIG.SYS
   file.  It  does  not  apply  to   the  references  to  SMARTDrive  in  the
   AUTOEXEC.BAT file. For more information about  using double buffering with
   SMARTDrive, see Chapter 14, "Optimizing Windows," in the Microsoft Windows
   User's Guide.
