If Value == 0x1 - BIOS Lock - Enabled If Value == 0x0 - BIOS Lock - Disabled 5) Remember the Value of VarOffset for change.
Part 2 - EFI Shell - AMISetupWriter 1) Create EFI bootable flash drive in FAT32 format. 2) Extract the contents of the archive "Boot_Shell_AMISetupWriter.rar" on the flash drive. 3) Reboot the PC in EFI Shell and run AMISetupWriter
Important! - An example is shown for the Asus Z87-Plus BIOS v2103. VarOffset, you, will be different. - If you have enabled the full UEFI mode, before booting from the flash drive be sure to disconnect Boot Security.

Hi, this tool is very practical, it can extract valid SETUP.TXT from ASUS ROG-STRIX-Z370-F-5605. However, the SETUP.TXT file extracted from the latest BIOS of the ASUS ROG-STRIX-Z370-F-GAMING-2401 does not have any valid data.
@jhsvip It is strange that Chinese providers block access to mail.ru resources.
I have poor access to Mega, maybe one of the users will upload files there. Important. It is necessary to update the IFRExtractor.exe to the latest version.
@SoniX - I currently have a Gigabyte GA-Z87-D3HP and I’ve been having trouble flashing the bios through QFlash and FPT. I don’t an OS running on the motherboard, so I’m using a freeDOS bootable usb drive to get my information from the bios. It looks like the BIOS Lock is enabled, so I’m assuming that this is the reason why I can’t flash anything, even the default bios.
How would I go through with using the second tool. I’m not sure how to create an EFI Bootable flash drive. My motherboard doesn’t have the feature to exit and launch an EFI shell.
What do you think about this error? HP OMEN 17 2020
Protected Range Registers are currently set by BIOS, preventing flash access. Please contact the target system BIOS vendor for an option to disable Protected Range Registers.
A nice guide. But at what moment do you get that mod_bios.bin??? After executing AMISetupWriter and reboot and use the fpt -d mod_bios.bin -bios command?
Hi everyone and thanks a lot @SoniX for this lovely tool, I’m wondering if I can use amisetupwriter command to change any value in the setup? I mean without having to make a modded bios and flash it.
