Compiling an NDIS 6.40 Driver
The WDK for Windows 8.1 supports header versioning. Header versioning makes sure that NDIS 6.40 drivers use the appropriate NDIS 6.40 data structures at compile time.
Add the following compiler settings to the Visual Studio project for your driver:
For a miniport driver, add NDIS640_MINIPORT=1.
For a filter or protocol driver, add NDIS640=1.
For information on building a driver with the Windows 8.1 release of the WDK, see Building a Driver.
For information on converting an driver's build files to a Visual Studio project , see Creating a Driver From Existing Source Files.
