摘要：
A boundary scan system for a data processing system using serial scan techniques for diagnostics comprises gated circuitry for each adapter card slot for controlling the propagation of controller generated diagnostic signals throughout the data processing system and the components included on the system's planar and each adapter card present, adapted to serially scan all present adapter cards and to provide electrical conduit to the next serially connected component in the absence of a card at an adapter slot.
