I haven't tried it yet. Would it allow me to mount root?
I tried to install from fixit once again, but I've made a script to eliminate 
all typo's I could made. I amde script using most of:

After rebooting it could even load bootloader:

I'll try to install FreeBSD in tuesday with new iso, as I suspect that 
something went wrong during burning dvd, also I didn't check md5. So maybe 
those problems are only related to defuncted dvd, I hope so.
