Isn't it possible to write drivers in assembly language? Or is WDK already assembly language and I'm being silly?

But for Windows executables it is possible to change things inside the file, if you have the PE/COFF specification for reference on what you're doing.

Of course you can write them in assembly language, but you still need to use the WDK (I'm pretty sure so).

By 'assembly language' I mean something like writing a program in NASM, linking with ALINK, then changing the filename from *.exe to *.dll

There must be some way to do it like this, I think.

I wouldn't count on it, really. I think there is more to making a driver than just compiling a DLL. But, why would you make an EXE and change it to a DLL instead of just linking it as a DLL?

DDK I have contains 12,997 files and 1,193 folders. I got the cd figuring one day I will toy with making a driver for something. From what I understand, drivers have different entry points than exe and dlls. Use different API calls, have to be signed (one of the reasons I finally got a code signing cert). The samples are in C/C++ but you use ASM if you want, just do some conversions. Drivers run in RING0 so it is more than changing the file extension...
