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.
