I'm hoping you guys can give me some insight, as I think option C might be the only possible way to get this up and running.
Don't use standard nvidia instaler. even vendor id and device id is matching is not working because of subsys or other details. Nvidia site if I remember right recomend for notebook chipset to search drivers from notebook manufacturer. Search on dell for drivers or use modified installer.
I tried updating the driver manually by going under device manager and clicking update driver. It says, "THE BEST DRIVER SOFTWARE FOR YOUR DEVICE IS ALREADY INSTALLED". That's when I try to install the driver under Standard VGA Graphic Adapter. I tried with Nvidia's 8 series mobile card drivers along with the inspiron 1520 and xps m1530 drivers which use this same video card. I think bios editing is the only way to get this to work
