Abstract
A method and article of manufacture, such as a magnetic disk containing computer instructions, for preventing a device driver from disabling an operating system during boot-up is provided. 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. The method includes a step of restoring registry information after the fault tolerant booting software attaches the device filters to identified device drivers. Messages are also displayed to identify a faulty device driver.
