I read a lot from your forum and wish sometime in the future I could test FreeBSD in Virtualbox, right now I can’t because my cpu too old, it’s just not support hardware virtualization
Why not take the plunge and install it to your HDD? You didn't say anything about machine specs but I have an i386 FreeBSD box with Intel Dual Core T2060 @ 1.6GHZ and 2GB RAM. It was what I used for years and is still of use.
FreeBSD is not Linux, but I can get you to a fully functional x11-wm/fluxbox desktop if you look in the How-To section for my tutorial.
