In computing, firmware is software that provides low-level control of computing device hardware. For a relatively simple device, firmware may perform all control, monitoring and data manipulation functionality. For a more complex device, firmware may provide relatively low-level control as well as hardware abstraction services to higher-level ...
Open Firmware is a standard defining the interfaces of a computer firmware system, formerly endorsed by the Institute of Electrical and Electronics Engineers (IEEE). It originated at Sun Microsystems where it was known as OpenBoot , and has been used by multiple vendors including Sun , Apple , IBM and ARM .
UEFI. In computing, BIOS ( / ˈbaɪɒs, - oʊs /, BY-oss, -ohss; Basic Input/Output System, also known as the System BIOS, ROM BIOS, BIOS ROM or PC BIOS) is firmware used to provide runtime services for operating systems and programs and to perform hardware initialization during the booting process (power-on startup). [ 1]
They can use different I/O protocols, but SPI is the most common. Unified Extensible Firmware Interface ( UEFI, / ˈjuːɪfaɪ / or as an acronym) [ b] is a specification that defines the architecture of the platform firmware used for booting the computer hardware and its interface for interaction with the operating system.
Odin is a utility software program developed and used by Samsung internally which is used to communicate with Samsung devices in Odin mode (also called download mode ). It can be used to flash a custom recovery firmware image (as opposed to the stock recovery firmware image) to a Samsung Android device. Odin is also used for unbricking certain ...
Smartphones. On smartphones, tablets, and other devices, an over-the-air update is a firmware or operating system update that is downloaded by the device over the internet. Previously, users had to connect these devices to a computer over USB to perform an update. These updates may add features, patch security vulnerabilities, or fix software bugs.
Libreboot (briefly known as GNU Libreboot[ 3][ 4]) is a free software project based on coreboot, aimed at replacing some of the proprietary BIOS firmware contained in some computers, though does require certain vendor code on some platforms as that code may not have been replaced with libre software. Libreboot is a lightweight system designed ...
OpenBIOS is a project aiming to provide free and open source implementations of Open Firmware. It is also the name of such an implementation. Most of the implementations provided by OpenBIOS rely on additional lower-level firmware for hardware initialization, such as coreboot or Das U-Boot .
