Within this EFI folder, create a folder called Boot. Get (or format) a blank FAT32 flash drive.Ĭreate a folder called EFI. Using the older, more popular setup_var command that’s hardcoded to look at the VarStore named Setup won’t work here!ĭownload the grub圆4.efi file from v1.0 alpha release available here. For readers who have used setup_var to modify EFI variables before, note that I am using a newer, special version of setup_var someone made that allows users to modify variables at a specific VarStore name. We now will prepare a special USB flash drive that will allow us to set the above “lock” variables to 0x0. To disable the CFG Lock, we need to set VarOffset 0x3E to 0x0 (replace 0x3E with the VarOffset for CFG Lock you see on your own machine, as it may not be the same as mine!) To disable the Overclocking Lock, we need to set VarOffset 0xDA to 0x0 (replace 0xDA with the VarOffset you see for Overclocking Lock on your own machine, as it may not be the same as mine!) We now know everything we need to move on to the next step:īoth the Overclocking Lock and CFG Lock options are stored in the CpuSetup VarStore. You should find one match, within the BIOS section of interest (“Setup”) Once the BIOS image is opened, do a search (Ctrl+F) on the Text (not Hex Pattern or GUID) for “Overclocking Lock”. Download, extract, and open the Windows app, and use the tool to open the BIOS dump we generated above (File…Open Image File) With the above BIOS dump in hand, it is now time to use UEFITool to search for the settings we care about, specifically the Overclocking. Extract Your System’s Setup Settings with UEFITool Once in the FPT folder, run the below command (different depending on your terminal of choice) to dump your current computer’s BIOS to your PC ( don’t forget the -bios part, and definitely don’t type something other than -d by accident, this tool can be dangerous if used improperly!): Unzip the Intel (CS)ME System Tools folder, and open up a command line or Powershell shell terminal window as an Administrator and navigate to the location of the “Flash Programming Tool” folder in the directory you unzipped, by changing directory with a command like the below:Ĭd "C:\Users\\Downloads\Intel CSME System Tools v14.0.11- r1\Flash Programming Tool\WIN64" Based on the version of Intel ME you are using, download the proper version of Intel ME System Tools listed here under header C2.
