So, it was discussed before and stated that it is disabled. At the same time it's possible to see it in device manager with modded BIOS. I have succes only in Safe Mode (you may see it on my screenshot). I was able to even install drivers and installer also founded device (usually it's just cancel installation because compatible device wasn't founded). I have black screen when trying to boot in Windows. I think it's just need proper configuration in BIOS, but which parameters need to be set?
Also there at least one Y500 which was able to boot in windows with proofs from GPU-Z (it's can't run in Safe Mode!), but with Error 43 on NVIDIA GT 650M.
