visual 2008로 커널개발시 c언어로 점프..

부트로더를 거쳐서 32비트 모드로 해서 동작하는것을 확인을햇습니다..

그리고나서 c언어로 가기위해서 visual 2008을 쓰는데요..

여기서 에러가 나네요

아래와같은 에러가 납니다...

model small로 바꾸면 저기 cpu mode 에러는 없어지는데요

pubilc과 extern명령어에서 또에러가 납니다;;

public과 extern 명령을 없애면 에러는 없구요...
뭐때문에 그런걸까요..흠.. masm에서 pubilc 명령과 extern명령이 없는건가요..?
제가 가지고 있는 책에선 masm으로 어셈블하는데.. 잘만되는데요..음..
