I guess that might include >some assembly language, but its just a very small part of the entire system. if you see the dll's as a lot of code then you're right, they're probably all c/c++ but if you just look to the basic kernel then the NT basic kernel is completely assembly. i assume nalimov who's not in the kernel team has a c/c++ branch to get to work at itanium. >> >>But for your notice, yes the released thing has major assembly parts in the >>kernel.
