Have you tried a vBAR=pBAR patch? See here for more details: http://www.davidgis.fr/blog/index.php?2011/12/07/860-xen-42unstable-patches-for-vga-pass-through This is mainly aimed at Nvidia GeForce cards (GeForce drivers don't handle the case where vBAR != pBAR, but Quadro drivers do - I modified my GeForce cards to equivalent Quadros to work around the issue). But - it may also help with your situation. It is entirely plausible that your GPU is having problems finding some of it's BARs, which might also explain why it is stuck in a low resolution / 4-bit colour mode. I am not sure how much you might need to adapt this and which patches you can skip or will have to modify for IGD instead of GeForce, but it's probably worth a shot. Gordan
