Hello, I unlock my bios using this thread http://forum.techinferno.com/lenovo-ibm/2874-lenovo-y400-y500-unlocked-bios-wlan-whitelist-mod.html But I could not flash it for sli. First of all I could not find the file .rom - it is removed I think. Secondly, I tried to GPU-Z to save bios as a .rom then I could not use Nibitor. Anyway I tried to use saved .rom file for nvflash with usb dos boot. There is an error which it is system protected occurred. Normally. I would use Nvidia Inspector for overclock but I can not use it before flash - unlock my bios for SLI. Is there another program for overclocking? I would be grateful if someone help me about the problem. Thanks.
