Thanks for answering.
Got it working yesterday.
FreeBSD suppose to work with its MBR entry on the active drive, i think it wasn't working because it was on second partition of not active drive, so easybcd's entry can't find it on boot.
I was rebuilding MBR, and moving it to FreeBSD's drive, and making it active.
Hope this will help to anyone. Goodluck to easybcd project.
