Hello, I know it's a really bad practice but I would like to understand the differences between BIOS and EFI mode in grub.
When I put "password user insecure" in the /boot/grub2/grub.cfg file in BIOS mode, grub recognizes my password and allows me to edit the grub configuration. On the other hand, when I'm in EFI mode (/boot/efi/EFI/centos/grub.cfg), the password doesn't work and I have the punishment delay increasing. The password_pbkdf2 command works correctly. Could you explain me the difference between the 2 modes? I searched in the source code but didn't find anything relevant. Thanks, Paul.
