If you compare the locked and unlocked files at posts #43 and #44 you can do it yourself with a hex editor

Hello, Would someone be kind enough to unlock my bios please.
I have compare the locked and unlocked files at posts 43 and 44
and I have looked at the patch file, I found a few digits but I am lost.

Thank you.
