Done, fried my onboard lan. Everything else seems fine after restoring the original bios, but I can't recommend this to others..
Against my better judgment, I am going to do it again and see what I can come up with. One thing that I noticed is after installing that modified ROM is my computer seemed much louder, I think it was just the fans. CPU temperature appeared high in the bios but normal when I booted and used System Monitor by NVIDIA.
