                         DRAM JUMPER CONFIGURATION

                Size                                  JP2

               256KB                           pins 2 & 3 closed

               640KB                           pins 1 & 2 closed

  Note: System memory is factory configured at 640KB and should not be
  removed. Setting JP2 pins 2 & 3 closed forces the system to only
  recognize 256KB.
