EFIjärjestelmässä

EFIjärjestelmässä refers to a system that utilizes the Extensible Firmware Interface (EFI) or its successor, the Unified Extensible Firmware Interface (UEFI). EFI/UEFI is a modern interface between an operating system and the platform firmware. It replaced the traditional BIOS (Basic Input/Output System) and provides a more robust and flexible boot process.

The primary function of an EFIjärjestelmässä is to initialize hardware components during the startup of a computer and then hand over control to the operating system's bootloader. Unlike BIOS, which had limitations in addressing large hard drives and offered less extensibility, EFI/UEFI supports larger storage devices and offers features like graphical boot menus, network booting capabilities, and enhanced security options through Secure Boot.

Key components of an EFIjärjestelmässä include the EFI firmware itself, installed on the motherboard, and EFI boot applications, which are small programs that reside on bootable media like hard drives or USB drives. These boot applications are responsible for loading the operating system. The EFIjärjestelmässä allows for a more standardized and modular approach to booting, enabling easier development of new firmware features and boot services. Understanding the EFIjärjestelmässä is crucial for tasks such as installing operating systems, managing boot order, and troubleshooting startup issues on modern computers.
