Don't you see a chicken-and-egg problem here? That file lives on a bfs volume. Some code somewhere that is not in that file has to know enough bfs to get to that file to be able to load it into the kernel. It's actually a farily interesting process. > M$ tried it with NT... (did they ?) Yes, and they failed so far, never reaching a good enough level of compatibility... until XP. XP feautres a different DLL cache, which allows different versions of the same DLL to live in the system at the same time, which allows to have "compatibility" version of the system libraries that emulat ehte broken behavior of various versions of Windows. -- Jean-Baptiste Queru <jb@xxxxxxxxx>
