An apparatus and method for integrated serial bus testing in a data processing system are implemented. During testing of the data processing system, serial bus test signals are provided via a predetermined input/output (I/O) device port. Switching circuitry decouples I/O device control circuitry from the I/O port in response to a control signal having a first predetermined value. The switching circuitry additionally decouples the serial bus controller from the serial bus interface which fans out the serial data lines to serial peripheral devices. During operation of the data processing system, the switching circuitry couples the serial bus controller to the interface, couples the I/O device controller to the I/O device port, and decouples the serial interface from the I/O device port, in response to the control signal having a second predetermined value.

A method for reducing the impedance of a reference path in a printed circuit board includes forming a printed circuit board having a plurality of conductive layers including first, second, third, and fourth layers. The printed circuit board includes two or more vias interconnecting two or more of the conductive layers. A first via is part of a signal path configured to carry a signal from the first layer to the second layer. A second via is part of a reference path configured to carry said signal from a third layer to a fourth conductive layer. The method further includes embedding an electrical component, such as a capacitor, in the second via between two of the conductive layers.

A ZIF connector includes a cover movable between an engaged position and a disengaged position, being moved by movement of an actuator having a flexible tab attached to facilitate movement of the lever. In the engaged position, pins of an integrated circuit mounted in the ZIF connector are held in engagement with terminals within the connector. When the actuator is moved toward the disengaged position by pulling the flexible tab, the pins are released for removal of the integrated circuit from the connector. The tab may be formed from a portion of adhesive tape.
