The EFI (Extensible Firmware Interface) system partition or ESP is a partition on a data storage device (usually a hard disk drive or solid-state drive) that is used by computers that have the Unified Extensible Firmware Interface (UEFI). When a computer is booted, UEFI firmware loads files stored on the ESP to start operating systems and ...
Class 0: Legacy BIOS; Class 1: UEFI with a CSM interface and no external UEFI interface. The only UEFI interfaces are internal to the firmware. Class 2: UEFI with CSM and external UEFI interfaces, eg. UEFI Boot. Class 3: UEFI without a CSM interface and with an external UEFI interface. Class 3+: UEFI class 3 that has Secure Boot enabled.

In the UEFI Shell, the SmbiosView command can retrieve and display the SMBIOS data. [15] [16] One can often enter the UEFI shell by entering the system firmware settings, and then selecting the shell as a boot option (as opposed to a DVD drive or hard drive).
To develop and implement UEFI (Unified Extensible Firmware Interface). The specification replaces BIOS as the software interface between your computer's hardware and OS, doing away with several ...
fwupd is an open-source daemon for managing the installation of firmware updates on Linux-based systems, developed by GNOME maintainer Richard Hughes. [1] It is designed primarily for servicing the Unified Extensible Firmware Interface (UEFI) firmware on supported devices via EFI System Resource Table (ESRT) and UEFI Capsule, which is supported in Linux kernel 4.2 and later.
In computing, BIOS (/ ˈ b aɪ ɒ s,-oʊ s /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is a type of firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup).

GNU-EFI and TianoCore are supported as main development platforms for writing binary UEFI applications in C to launch right from the rEFInd GUI menu. Typical purposes of an EFI application are fixing boot problems and programmatically modifying settings within UEFI environment, which would otherwise be performed from within the BIOS of a personal computer (PC) without UEFI.
rEFInd, a boot manager for UEFI systems. coreboot is a free implementation of the UEFI or BIOS and usually deployed with the system board, and field upgrades provided by the vendor if need be. Parts of coreboot becomes the systems BIOS and stays resident in memory after boot. Das U-Boot is a bootloader for embedded systems. It is used on ...
