Installation of freeBSD is a lot different than Other distro i.e. Fedora and Ubuntu. I had installed freeBSD as a virtual machine on Fedora 9.0. with Sun's Virtual Box. During installtion VirtulaBox automatically assign 2GB harddisk space. But when i selected Automatic paritions allocation it raised and error "no space to create partition /usr. After aloting 4GB space it works fine. After installation created the user with "adduser" instead of useradd. adduser command ask lot of quesion while creating. Installtion of packages is a difficult task. Had installed the X-servers/Gnome packages But still unable to run Gnome on FreeBSD.

* Enable root login: login as root. Issue the command 'pw mod user <username> -G wheel'. After issuing this command you'll be able to login as a root from given <username>

* Gnome on FreeBSD: Download the gnome package either during the installation or separately. As a root user add the line 'gnome_enable="YES"' to /etc/rc.conf, then reboot your machine. When you'll boot up you will see gnome desktop environment.
