So those images won't work with VIA P4M800 graphics. I prefer using the archived 12.04.1 images because I have too many computers spread out over too large of an area and the original Precise kernel and X-stack is supported until April 2017 whereas the later point releases will require either upgrading to Trusty, or to the Trusty HWE stack by August 2014.
