Unified Extensible Firmware Interface (UEFI, / ˈ juː ɪ f aɪ / or as an acronym) [c] is a specification for the firmware architecture of a computing platform. When a computer is powered on, the UEFI-implementation is typically the first that runs, before starting the operating system.
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 ...
An option ROM for the PC platform (i.e. the IBM PC and derived successor computer systems) is a piece of firmware that resides in ROM on an expansion card (or stored along with the main system BIOS), which gets executed to initialize the device and (optionally) add support for the device to the BIOS.
In this guide, we'll show you the steps of creating a USB flash media to perform an in-place upgrade or clean installation of Windows 10 on computers using UEFI firmware with the Media Creation ...
Logo of Tianocore, the umbrella project of which EDK II is part of. TianoCore EDK II (formerly Tiano) is the reference implementation of UEFI by Intel.EDK is the abbreviation for EFI Development Kit and is developed by the TianoCore community. [1]
Unified Extensible Firmware Interface (UEFI) is a successor to the legacy PC BIOS, aiming to address its technical limitations. [5] UEFI firmware may include legacy BIOS compatibility to maintain compatibility with operating systems and option cards that do not support UEFI native operation.
INT 13h is shorthand for BIOS interrupt call 13 hex, the 20th interrupt vector in an x86-based (IBM PC-descended) computer system.The BIOS typically sets up a real mode interrupt handler at this vector that provides sector-based hard disk and floppy disk read and write services using cylinder-head-sector (CHS) addressing.
