This is the standard way to boot "unsupported" os in grub, perhaps the fbsd can be loaded without this line? I don't know...but from the original post, it seems that this line is critical(?).

btw, I didn't install any bootmgr during fbsd installation.

Freebird

Please give me a link,I want to know more about it ,thanks in advance!
