   me.com/intr/rb-1601.htm (only need to have one as an example) says POINTING   
   DEVICE BIOS INTERFACE (PS), does the PS at the end not mean PS/2 or is it a   
   certain set of PS/2 mice that it    
   supports?   
      
   behind INT15C2xx there are more mouse functions available.   
   C207 let you set your handler address but it doesn't save you from   
   enabling IRQ12.
