Hello guys,  I would like to unlock my laptop advanced bios settings to change dvmt and cfg lock settings. Is there a button combination to do that? If I flash a modded bios, Can I get back to the original bios I had? Thanks.

Hi
Need your bios dump only

Thanks, but I can't dump bios because it gives me an error 201 on ftpw64.exe file.
