=Installing Ubuntu=
*The instructions below are written for linux. I installed from a Ubuntu live USB drive (Ubuntu 13) on my macbook pro (os x 10.8).
*Once you are booted in ubuntu on your non-beagleboard system, follow instructions here: 
**http://elinux.org/BeagleBoardUbuntu#Method_1:_Download_a_Complete_Pre-Configured_Image
*there will probably be missing packages
*you may need to add universe to package repository to get those missing packages:
