An Overview of the HP OSI Express Card. The OSI Express card provides on an I/O card the networking services defined by the ISO OSI (Open Systems Interconnections) Reference Model, resulting in off-loading much of the network overhead from the host computer. This and other features set the OSI Express card apart from other network implementations in existence today, by William R. Johnson, pg 6-8

The HP OSI Express Card Backplane Handler. The backplane on the HP OSI Express card is handled by a pair of VLSI chips and a set of firmware routines.
