  • Method and apparatus for disabling a graphics device when an upgrade device is installed
    Patent number: 6243782
    Abstract: One embodiment of a graphics device that can be disabled when an upgrade graphics device is installed is described. The graphics device includes an interface to a bus and an input to receive a device disable signal. When the device disable signal is asserted, the interface to the bus places its buffers in a high impedance state, meaning that the graphics device is electrically isolated from the bus. When the device disable signal transitions from asserted to deasserted, a reset circuit in the graphics device resets the graphics device.
