Fault tolerant booting software is provided in a computer having remote control software. The computer is able to provide video information to another remote computer in response to a user's input. The fault tolerant booting software interfaces with the computer's various device drivers, including, a video driver, keyboard driver, and a pointing device driver. The fault tolerant booting software attaches to identified device drivers to prevent a faulty driver filter from rendering the operating system inoperable for failing to load during a bootstrap routine.
