An apparatus for cryptographic pre-boot authentication includes a cryptographic processor configured to perform cryptographic operations. Each of the shoes travels along at least one of the slats in order to laterally divert articles on the conveying surface. The wafer holding member has a wafer mounting surface and may preferably have a conical head having a tapered peripheral wall and a cylindrical portion. Based upon the topology information and the various forms of mapping information, a user is able to navigate through a web-based user interface to determine root causes of network problems. The secondary device may initiate the full-duplex link initialization stage, during which any handshaking signals may be exchanged, by transmitting signals to the primary device.
