Remove the FreeBSD boot manager

[Tom Smith]

I'm somewhat new to FreeBSD and decided to install the Boot Manager 
during installation.

Since, I've decided to make this machine a FreeBSD-only server (no dual 
booting) and would like to remove the Boot Manager to enable faster boot 
times (the Boot Manager adds about 10 seconds to boot time).

How can I remove it without any major issues like having to reinstall 
from scratch?
