I have an n450 dev. board that was steaming along just fine until I updated Ubuntu yesterday. The update required a reboot and during that reboot the machine hung during POST with a '0d' code.
I have video, and I attempted to enter the BIOS setup. I see the 'Entering setup...' message but it never gets there.
I've tried removing the HD, thinking an issue with the MBR, etc. was hanging it up -- No Joy.
