  Note: The values in this table are only valid if no option board memory
  is used for backfill and no 384K offset is used. To set starting memory
  address if backfill or 384K offset is used, set SW2 to the correct
  value. SW2/1 is the most significant bit and SW2/4 is the least
  significant bit. The switches have the following values: SW2/1=512KB,
  SW2/2=1024KB, SW2/3=2048KB, and SW2/4=4096KB. Turn the switches on and
  add the values to set the starting memory address. (On=1, Off=0)
