1. A networking interface device for coupling a system host having one of a plurality configurations to a network medium, comprising:

  • a peripheral component interconnect (PCI) interface for coupling the interface device to a system host configured with a PCI based system bus interface;

    a medium independent interface (MII) for coupling the interface device to a system host configured with a media access controller (MAC) based system bus interface; and

    a control block for determining whether the interface device is operably coupled to a system host having a PCI based system bus interface or a MAC based system bus interface, wherein the control block determines that the interface device is coupled to a system host having a MAC based system bus interface by detecting the presence of at least one of a management data clock (MDC) or a management data input/output (MDIO) signal transmitted from an MII on the system bus interface to the MII of the interface device.
