Hi, I'm totally new to NDIS and drivers in general. I need to create my own NDIS protocol driver. To begin with it can have the exact same functionality as ndisuio, so here is what I've done: (1) Copied ndisuio source tree and renamed it (2) In the sources I renamed protName, NT_DEVICE_NAME and DOS_DEVICE_NAME (3) Chose a different name for the target sys file (4) Built the driver - it build successfully I also copied ndisuio.inf file, made some renaming in there, but unfortunately the driver doesn't install. I believe the problem is in the INF file but I don't know how to fix it. Is there any reference/sample that explains exactly how to create the inf file? Regards, Osnat
