Have you followed any guides or howtos for this? Keywords like "vfio", "nvidia", "geforce" turn up thousands of hits on google. I've done a talk on it, that plus more hands on videos from others are also on youtube. Optimus is generally much harder to get working than discrete cards. Stopping at the option ROM might mean we're not reading it properly from the GPU, it might need to be provided separately. There are all sorts of guides online to do that as well. Thanks, Alex
