I installed Pro 2.0 using a composite cable and managed to get X working. I now want to get it working with my X2VGA+. I ran xbvset and chose the X2VGA resolutions. The box rebooted and I ran gentooxx.xbe from EvoX. The screen went black, the fan sped up and then the box just powered off.
I have looked at some other posts on here which have suggested booting from the CD, and booting from a dash with a 480p resolution. Booting from the CD made no difference - I selected fatx in the bootloader and then the same thing happened. So I set XMBC to a 480p/16x9 resolution and ran gentooxx.xbe. Same thing.
If I change back to the composite cable, it boots fine and X still works, but obviously at low res.
I think it's a 1.2 or 1.3. I can't be sure given the info on Xbox-Scene. Motherboard identification is unclear, and s/n identification suggests either a 1.2 or a 1.3. Why is this significant? It's a Conexant video chip if that's what you need to know.
