MORE INFORMATION

When you develop an NDIS 3.0 driver, half of the code is common for all NDIS drivers and the other half is specific to hardware. Miniport is an extension to the NDIS 3.0 specification which allows developers to write code specific to the hardware and merge the common interface to the NDIS wrapper.
