A design method of network device driver based on EFI is presented.To begin with
the inherent EFI driver model is studied and the Universal Network Driver Interface and Simple Network Protocol are analyzed.It provides the basic interface and services for the implement of network device drivers.It analyses the structure and the component of EFI network device and puts forward a 3-layer model for EFI network device driver scheme according to the features of EFI network device.How to implement EFI network device driver in the form of EFI driver is introduced.Finally
by designing and implementing the basic functions of network device
a basic process of network device drivers based on EFI is presented.
