Hi Roland. Boy am I glad that I asked. That is probably the last thing I would =20 have done. Plus thanks for the answer, I must not have done a proper =20 search. I hope that the apps will run after reinstalling. I assume that the =20 source tree will somehow recognize that I will be building world and =20 the kernel on a AMD64. I'm downloading a copy of disk2 from FreeBSD =20 now. Have a great day. ed
