It's just a HP dm4 (dm4-2070us) off the shelf
carpan, I followed very similar steps, but I'll give those a try after work. Thanks guys.
The DM4-207us has an Intel 3000 HD and Fall out 3 doesn't support integrated graphic cores out of the box. You'll need to use the D3D9.dll file originally developed for Oldblivion to start the game.
Follow the steps I gave you, turn on xp compatibility and lower the settings down and it should run poorly but playable. (around 24ish fps.)
