I am writing an application for an Emmerson NITX 316 board. It has Atom E640 and EG20T I/O hub. I have got drivers from Intel for EG20T for Windows XP and Windows 7. But the driver package does not include and documentation on how to use the functions included. The driver package included a header file for enums and typedefs and a header files listing ioctls. It is not possible to use the driver functions without more details on their use.
Where can I find User documentation of the EG20T driver functions?
