Hi Dudes,
When I was purchasing my Beagleboard XM years ago, there was a feedback form, to mention what you intended to use it for. I said a dedicated XBMC device or a File Server. I been messing with it for years and I loved the DB9 serial to usb connection personally.
But lately I found it is awesome as a dedicated radius server. So if you dont know what to do with yours, try installing ubuntu and freeradius.
Best Regards
Aubrey.
