   //wiki.osdev.org/%228042%22_PS/2_Controller it has "0xA9 	Test second PS/2   
   port (only if 2 PS/2 ports supported)" so that's what I'm doing, I'm testing   
   the port.   
      
   OK, it's a wiki page :)  so modified by many and not all know best.   
   I checked on and it doesn't tell anything about 9C.   
   perhaps your virtual or OLD hardware haven't PS/2 mice support at all.   
      
   I'd try it again without CMD A9 and assume you have both PS/2 conns,   
   or look at the back of you PC and count PS/2 connectors :) :) :)   
      
   If there is non or just one for KBD then your PC isn't that old and   
   support/emulate PS/2 over USB (like mine show that).
