What is the difference between UEFI boot and BIOS boot in principle?

Interface, namely "Unified Extensible Firmware Interface", is a standard that describes a new type of interface in detail. It is a standard firmware interface for computers, which is designed to replace BIOS (basic input and output system).

System). This standard was created by more than 40 technical companies in UEFI Alliance/KLOC-0, including Microsoft. UEFI aims to improve software interoperability and solve the limitations of BIOS.

To learn more about UEFI, we have to start with BIOS. As we all know, every ordinary computer has a BIOS, which is used to load the most basic code of the computer and is responsible for initializing the hardware.

The task of detecting hardware functions and booting the operating system. UEFI is a concept opposite to BIOS. This interface is used to automatically load the operating system from the pre-boot operating environment to the operating system, thus realizing

The purpose of saving time is to simplify the startup procedure. Traditional BIOS technology is gradually being replaced by UEFI. Recently, many newly manufactured computers have used UEFI and installed in UEFI mode.

System is the trend.

UEFI, as the successor of traditional BIOS, has many functions that its predecessors did not have, such as graphical interface, multiple operating modes, allowing the implantation of hardware drivers and so on. These characteristics make UEFI easier to use, richer in functions and more convenient than traditional BIOS. Windows 8 announced its full support for UEFI at the beginning of its release, which also prompted many motherboard manufacturers to switch to UEFI and make it one of the standard configurations of motherboards.

UEFI eliminates the problem that traditional BIOS needs long-time self-check, and makes hardware initialization and boot system simple and fast. In other words, UEFI changed the BIOS of the computer.

It is a BIOS, just a small operating system solidified on the motherboard. In addition, the development language of UEFI itself has also changed from assembly to C language, and the addition of high-level languages makes it possible for manufacturers to deeply develop UEFI.
