   Here is a copy of my mouse driver!
//init stuff:
Regs.x.ax=2;
__dpmi_int(0x33,&Regs); //hide cursor
Regs.x.ax=4;
Regs.x.cx=600;
Regs.x.dx=400;
__dpmi_int(0x33,&Regs); //set mousepos
mouseX=600;
mouseY=400;

Regs.x.ax=7;
Regs.x.cx=0<<3;  // take coordinate times 8 (This is a problem i hawe,
meady you can solve it for me? the mouse mover 8 stepps at a time)
Regs.x.dx=320<<3;
__dpmi_int(0x33,&Regs); //set xboundaries
Regs.x.ax=8;
Regs.x.cx=0<<3;
Regs.x.dx=200<<3;
__dpmi_int(0x33,&Regs); //set yboundaries



and then read from the mouse! :
        Regs.x.ax=3;
        __dpmi_int(0x33,&Regs);
        mouseX=Regs.x.cx>>3;
        mouseY=Regs.x.dx>>3;
                if(Regs.x.bx & 1)
left button pressed
                if(Regs.x.bx & 2)
right button pressed
               if(Regs.x.bx & 4)
middle button pressed
