So after countless hours of trying to extract the IFR Tables from the Setup part of the bios in my precision, ive kinda given up. my plan is to figure out which variables i can change with the setup_var command booting from a uefi grub terminal to "unhide" and unlock the overclocking parts of my bios setup. I originally found out that this was possible from this guide right here --> (https://www.nbrchive.net/forum.notebookr...index.html) and while the guide gives me some variables i can change it doesnt give me all of em, specifically the one to unlock access to the hidden advanced menus of its AMI Aptio IV bios, so I dumped my bios (version A16) and extracted the Setup file of the BIOS with UEFI tool, Ive tried countless softwares to extract the IFR tables from the Setup.efi file, and nothing wants to work. Any help with getting those variables or even creating a custom bios would be greatly appreciated. ive attached both the Setup.efi (here in a google drive link since i cant attach the file directly: https://drive.google.com/file/d/1je7udBj...sp=sharing )file and the entire dump of my bios. also here is the list of variables i do know from the guide (copied directly from it):
