Cannot update 12th gen mainboard BIOS without battery

How can I update my 12th gen mainboard from BIOS version 3.05 to 3.08 without a battery installed? I have the mainboard in a 3D printed case, stand alone. I do have the CMOS battery installed if that matters.

From here: 12th Gen Intel Core BIOS 3.08 Release

Hopefully that helps!

This is what happens when I try to install using the EFI method.

Ah, I’m sorry for leading you astray. I don’t have a 12th gen board, and skimming that long thread, it looks like they still don’t have an EFI updater that works reliably.
