Lenovo Z70-80

[dragopas]

Hello, I am using Lenovo Z70-80 with Intel HD5500U and i7500U BIOS (B0CN96WW). I would Hackintosh, but environment is DVMT 0x18C 0x1, and I want to change to 0x18C 0x3. No options Setup Tab in my BIOS, I used this guide:http://www.tonymacx86.com/yosemite-laptop-support/165104-guide-broadwell-hd5500-setting-dvmt-insydeh20-bios-laptops.html

but give error (Could not write value), also used this version (B0CN96WW) but nothing, maybe the BIOS is encrypted or locked. You are able to make this change and help me, in exchange for a small donation could make good beer. Greetings
