Uefi (Unified Extensible Firmware Interface) Done by Nuriddinov Davron, student of group 424-21

UEFI accessibility Users can download the UEFI specification from the UEFI Forum website. The most recent version, UEFI 2.9, features several enhancements, including the following: supports devices based on the new Compute Express Link interconnect; supports publishing Linux Device Tree Blob binary format files that identify computer components in the UEFI configuration table; and clarifies how UEFI-based update runtime calls are made on certain Advanced Reduced Instruction Set Computing Machine server

Coreboot and UEFI With the industry gradually phasing BIOS out, UEFI receives most of the attention as the heir apparent. However, open source Coreboot is another option vying to replace legacy BIOS, and its proponents claim it is faster than UEFI. Coreboot, formerly known as LinuxBIOS, is purportedly able to replace proprietary BIOS and UEFI firmware -- with underlying benefits of extreme performance, minimal resources to boot machines and security measures that include a minimal trusted computing base and virtual boot disk. Coreboot code was first introduced in 1999, and the community-based development project's supporters include Google, whose Chromebook devices replaced BIOS with Coreboot since the first generation. Coreboot's market penetration has been slow, however, due to the work it entails on the part of manufacturers. Since Coreboot initializes only Bare metal, device makers need to make the effort to port the code for integration in chips and motherboards.

Conclusion In conclusion, Unified Extensible Firmware Interface (UEFI) has become a crucial component in modern computer systems, replacing the traditional BIOS (Basic Input/Output System). UEFI offers numerous advantages, such as improved security, faster boot times, support for larger storage devices, and enhanced flexibility for developers and system administrators. One of the key benefits of UEFI is its secure boot feature, which ensures the integrity of the boot process by verifying the digital signatures of firmware and operating system components. This helps protect against malware and unauthorized modifications, thereby enhancing the overall security of the system. Additionally, UEFI enables faster boot times through its optimized initialization processes, allowing users to get to their operating systems more quickly. It also supports modern storage technologies, such as GUID Partition Table (GPT), which allows for larger and more efficient disk utilization.
