What is the function of UEFI?
UEFI defines a new method by which OSes and platform firmware communicate, providing a lightweight BIOS alternative that uses only the information needed to launch the OS boot process. In addition, UEFI provides enhanced computer security features and supports most existing BIOS systems with backward compatibility.
What is the benefit of UEFI boot?
UEFI provides faster boot time. UEFI has discrete driver support, while BIOS has drive support stored in its ROM, so updating BIOS firmware is a bit difficult. UEFI offers security like “Secure Boot”, which prevents the computer from booting from unauthorized/unsigned applications.
What are the benefits of UEFI?
Benefits of UEFI boot mode over Legacy BIOS boot mode include:
- Support for hard drive partitions larger than 2 Tbytes.
- Support for more than four partitions on a drive.
- Fast booting.
- Efficient power and system management.
- Robust reliability and fault management.
