UEFI requires the firmware and operating system loader (or kernel) to be size-matched; that is, a 64-bit UEFI firmware implementation can load only a 64-bit operating system (OS) boot loader or kernel (unless the CSM-based legacy boot is used) and the same applies to 32-bit.
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.
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).
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 ...
The Video BIOS provides some basic display services for BIOS and operating systems, for example INT 10H (Legacy BIOS), VBE (Legacy BIOS) and UEFI GOP. The original IBM PC BIOS included integrated support for the IBM CGA and MDA video adapters (and did not support option ROMs at all), so those video cards had no option ROMs.
UEFITool is a software program for reading and modifying EEPROM images with UEFI firmware. [1] It is written in C++ using the Qt library. [2] Features include the ability to view the flash regions and to extract and import them. [3] UEFITool allows the user to search for hex and text patterns. [4] UEFITool presents UEFI firmware images in a ...
The Windows Boot Manager (BOOTMGR) is the bootloader provided by Microsoft for Windows NT versions starting with Windows Vista and Windows Server 2008.It is the first program launched by the BIOS or UEFI of the computer and is responsible for loading the rest of Windows. [1]
In the context of GPT on a BIOS-based computer, a BIOS boot partition is similar in some respects to the EFI system partition, which is used by systems based on EFI. The EFI System partition holds a filesystem and files used by the UEFI, while the BIOS boot partition is used in BIOS-based systems and accessed without a filesystem by holding raw ...
