In the last thread you linked, theres 2 methods for boards without USB BFB, the AFUWIN /GAN (Not AFUDOS), specific version is noted and the AISuite method, so read it again please.
FPT method only after mod with AMIBCP for changing Bios Security settings and then it can be read/written.
Is there a method available without installing any Microsoft Windows previously on this system?
I’ve found only one version of AMIBCP which requires Windows.
If only Windows-based methods exists which Windows version (available: XP 32-Bit, Vista 32-Bit, 7 64-Bit, 10 64-Bit, 11 – all temporarily available for short time “test” installation without internet access & activation only) should be installed?
“I’ve found only one version of AMIBCP which requires Windows”…
Plenty of this around the web… this is leaked AMI tools. You need v4.x
FTP EFI/DOS also exists… the rest of methods are windows based.
The mods can be done on another system and the SPI flash can be done with a IC programmer, the IC is SOIC8 3.3v so its straight attached on a simple CH341A device.
Trying method 2 for Asus mainboards described here with freshly installed Windows 10 pro 64-Bit en_US (to avoid any language mismatch) and chipset driver downloaded from Asus gives following results:
Flash the original BIOS by running the following Command Prompt (as Admin): afuwinx64.exe <NAME OF THE ORIGINAL BIOS>.CAPWorks.
Remove the capsule header from the modded *.CAP BIOS file and save the modded BIOS as *.ROM file. Works, done with UEFITool.
Flash the modded BIOS by running the following Command Prompt as Admin: afuwinx64.exe <NAME OF THE MODDED BIOS>.ROM /GANWorks.
The UEFI BIOS should now be fully re-flashed and updated! Reboot and give it a try! Fails! Mainboard is dead, no visible screens, no beeps from speaker after reboot. CMOS reset & temporary CMOS battery removal doesn’t change anything.
