UEFI (Unified Extensible Firmware Interface) is a new generation EFI (Extensible Firmware Interface) standard, which is an interface type used for computer system startup. The UEFI standard is widely used on many computer platforms, including desktops, laptops, servers, and mobile devices. UEFI is different from the traditional BIOS (Basic Input/Output System) and has better compatibility and scalability, while also providing better virtualization management functions and security performance.

UEFI firmware bootloader provides better performance than BIOS and also allows system administrators to customize boot options to meet specific business needs. UEFI adopts a driver-based modular design idea to divide the main functions of the firmware into different modules, which can be loaded at runtime, thus improving flexibility. Compared with BIOS, UEFI also supports code signing on the device, which means that only code with the correct signature can be loaded and executed, thus enhancing the security of the platform.

In UEFI mode, the operating system is able to utilize more memory (including cache and memory sticks), and use more advanced features and tools to manage and control the platform. At the same time, UEFI also provides a simpler and more intuitive graphical interface, making it easier for users to operate. All in all, UEFI is a major trend in future computer systems. Its emergence will provide better performance and security for enterprises, individual users and operating systems.
