Hello, I recently started developing EFI applications. I made a simple specs checker and some kind of login system, which asks the user for a password in a loop until the right password is entered. It is not a driver, only a simple EFI application. Is it possible to add that to the BIOS boot, so the .efi gets executed while the firmware is loading? I know how to add it to the Windows boot loader, but I want it to be implemented in firmware. It should execute the .efi before one boots to the BIOS menu.
