   |     Note: A total of 255 BIOS address settings are         |
   |     available. The switches are a binary representation of |
   |     the decimal memory addresses. SW1/8 is the Most        |
   |     Significant Bit and switch SW1/1 is the Least          |
   |     Significant Bit. The switches have the following       |
   |     decimal values: SW1/8=8,388,608, SW1/7=4,194,304,      |
   |     SW1/6=2,097,152, SW1/5=1,048,576, SW1/4=524,288,       |
   |     SW1/3=262,144, SW1/2=131,072, SW1/1=65,536. Turn off   |
   |     the switches and add the values of the switches that   |
   |     are off to obtain the correct memory address. (Off=1,  |
   |     On=0)                                                  |
