One thing to keep in mind on AT boxes is that interrupt 2 was eaten
up by the second dma controller. The way to access int 2 is to use the
physical int 2 line on the hardware card, but to use INT 9 on the
software side, as this is where the int 2 line was connected to upon
the addition of the second dma controller.
