UEFI history
- Early 2000s: Intel developed the first version of UEFI to improve upon the legacy BIOS system, especially for larger systems.
- 2005: The Unified EFI Forum, a group of big tech companies, took over UEFI aiming to make it the industry standard, replacing BIOS.
- Ongoing: UEFI is now the standard for new computers because it’s better suited for modern computing needs.
UEFI uses
- Personal computers. UEFI is common in personal computers, both desktops and laptops.
- Servers. It is also used in server hardware for better control and security.
- Embedded systems. Some embedded systems, like advanced IoT devices, use UEFI for its flexibility and security.
UEFI advantages
- Support for larger drives. UEFI supports hard drives over 2 TB, overcoming the limitations of BIOS.
- Faster boot times. UEFI reduces the time it takes for a computer to boot up.
- Advanced security features. It includes features like secure boot, which helps protect against malware during booting.
- Network booting capabilities. UEFI allows remote diagnostics and repair, even without an operating system installed.
- Flexibility. Being modular and extensible, it can be easily updated and customized.
- Graphical user interface (GUI). Unlike BIOS, UEFI can support a GUI, making it more user-friendly.
- Support for modern standby modes. Better power management capabilities for more energy efficiency.
