uefi is called "Unified Extensible Firmware Interface", and compared to traditional BIOS, what are the advantages?

In order to solve the problem of traditional BIOS, Intel launched the EFI (Extensible Firmware Interface) standard for IA64 (64-bit processor) in 2000 as the specification for a new generation of BIOSes, and the BIOS that supports the EFI specification is also known as EFI BIOS.



UEFI DualBIOS? Technology
At the heart of this exciting new technology is a new generation of DualBIOS? technology that combines the latest in DualBIOS? technology with the latest in DualBIOS? technology, allowing users to take advantage of the next generation of DualBIOS? technology without having to compromise on performance. support over 100TB size hard disk and 100 primary partitions, which is especially useful for users using Win7. On the other hand, 32-bit systems + traditional MBR partitions can also use 2TB+ hard drives via "virtual disks" and the like, thanks to the efforts of vendors like Asus, Gigabyte, and Seagate, but that's not as easy as the native support of UEFI+GPT, of course.

2. UEFI provides better performance

The traditional BIOS is customized for legacy 16-bit processors with poor addressing capabilities and poor performance, while UEFI can be applied to any 64-bit processor with much stronger addressing capabilities and better performance -- in other words, more loaded.

3, 64-bit new systems have the advantage

From Windows Vista SP1 and Windows Server 2003, as long as the 64-bit system can provide UEFI boot support, while the XP system, the 32-bit new system, can only be compatible with the module through the UEFI to realize the boot.

4. More convenient batch installations

UEFI-equipped motherboards can be used for "broadcast" installations over the Internet, where an image is broadcasted to multiple machines to install the operating system, which is especially convenient for enterprise users.

5. Faster boot and hibernation resumes

The traditional BIOS uses Int 13 to interrupt the reading of disks, and can only read 64KB per session, which is very inefficient, while UEFI can read 1MB per session and load faster. In addition, Microsoft's next-generation operating system, Win8, is further optimized to support UEFI, which is said to enable instant boot.

6, more secure startup

Previously there were rumors that Win8 uses UEFI to limit the survival of Linux and other systems, in essence, this design is to prevent the user from running unauthorized code, to ensure better security, the user can choose to turn off this feature if they do not feel the need.
