[starikarp at yandex.com]

Hi!

I asked long ago about hard drives and I decided and order the new WD
black 1TB for my iMac 11,1 where I have installed FreeBSD from version
6?.
I decided to change HD by myself but the problem is (which I didn't
solved yet) how to put operating system on. First I hope that I can
just put FreeBSD CD in and install like on PC but I heard that doesn't
work. 
Does anyone know a trick how should I solved the problem, please.
Now I have OS X (Mountain Lion) on and I use rEFIt as boot manager.
