I did some in the comp.unix.bsd.freebsd news group, and I found some people with the same problem. I'm suspecting that it is impossible to boot FreeBSD by using NTLDR to load the FreeBSD boot sector from a file when FreeBSD is placed on a second disk. Can anyone confirm that this is the case? (the news group postings were very old). And why is it so? Thanks for any answers.
