   |Note: The Rampage AT may be set for any memory address from |
   |0K to 15896K, Each switch represents a quantity of memory.  |
   |SW2/1 is the Most Significant Bit and SW2/7 is the Least    |
   |Significant Bit. The switches have the following values:    |
   |SW2/1=8192K, SW2/2=4096K, SW2/3=2048K, SW2/4=1024K,         |
   |SW2/5=512K, SW2/6=256K, and SW2/7=128K. Turn off the        |
   |switches and add their values to obtain the correct starting|
   |memory address. (Off=1, On=0)                               |
