The Beagleboard xM has a unique CPU ID register that I have been using to keep track of our systems. Now that I have started using the Beaglebone I do not see a similar register. Is this just my RTFM incompetence, or does the Beaglebone not have this feature?

Thanks so much for your quick reply, that was very helpful. For others, it appears that SPRUH73B has been superseded by:
