We are assuming that you are accessing MS-DOS through the Windows "Run CMD" capability. Since the normal Windows keyboard and mouse drivers are still running, the orbiTouch® will work fine. As for the optical mouse, that should work also. If the optical mouse is occupying one of the PS/2 ports, we suggest that you plug the orbiTouch® in via the included USB adapter
