But you're almost right; the code in question will be at 0xcf0d3 offset in /dev/mem, so: # dd if=/dev/mem iseek=0xcf0d3 bs=1 count=16 | ndisasm -- ... every activity meets with opposition, everyone who acts has his rivals and unfortunately opponents also. But not because people want to be opponents, rather because the tasks and relationships force people to take different points of view.
