A.1.2.3 Full NIC Driver Sample Code

As mentioned earlier, the DDK for Windows NT includes code for several sample miniport NIC drivers. For sample code to full NIC drivers, you will have to use the older DDK from Windows 3.1. For more information about this sample NIC driver, see Section A.4.

The sample code is based on an Ethernet driver that controls a MIPS-based network interface card using the SONIC integrated circuit, manufactured by National Semiconductor. The sample driver contains functions that you can adapt to your own purposes. There are always hardware-dependent functions that only you can write. However, many functions (primarily those that communicate with the NDIS interface library instead of a network interface card) are fairly standard. You can use these with little or no modification.
