I'm sorry, I thought BIOS Lock was off by default, at least that's how it was indicated in textual representation of UI. So I focused on another lock, but it wasn't the only one. I'll try to do something about it but I may ask for more information soon. I can't imagine how, because I literally deleted all 3 parts: ACPIHeader, PublicKey and WinMarker. By the way, Microsoft dropped the use of SLIC to activate system starting from Windows 8. Now the MSDM key built into the BIOS is used. It can't.
