Single-Board Computers
The Raspberry Pi computer series do not have a battery source to ensure that firmware settings are saved even if the computer loses power. This means that they do not use a conventional BIOS or EFI architecture.
Instead, these systems use a configuration file that is stored on the hard drive and used to configure the system during the boot process. These settings are configured through the command line or a graphic user application.
