Abstract
A method and apparatus for maintaining automatic termination of a bus in the event of failure of a host computer are disclosed. The method includes the steps of (a) powering a first termination control circuit and a first terminating circuit of the first bus controller with the bus; (b) generating a first control signal (1) that is of an enable state if the first bus controller is located at an end of the bus, and (2) that is of a disable state if the first bus controller is located in a middle portion of the bus; (c) coupling the first terminating circuit to the bus if the first control signal is of the enable state; and (d) decoupling the first terminating circuit from the bus if the first control signal is of the disable state.
