How much do you know about the differences between BIOS and UEFI?

BIOS and UEFI - The Future of BIOS

BIOS is an acronym for "Basic Input Output System", which means that the Chinese name for UEFI is "基本输入出系统". UEFI is also known as Unified Extensible Firmware Interface. Firmware Interface, i.e. "Unified Extensible Firmware Interface", is a standard that describes in detail a new type of interface, a standard firmware interface for computers, designed to replace the BIOS (Basic Input/Output System), UEFI is designed to improve software interoperability and solve the limitations of the BIOS. limitations.

Note: Advantages of UEFI over BIOS

1. Increases security by protecting the pre-boot or pre-boot process against bootkit attacks.

2. Reduced boot time and recovery time from hibernation.

3. Supports drives with capacities greater than 2.2 TB.

4. 64-bit support for modern firmware device drivers, which can be used by the system to address over 17.2 billion gigabytes of memory during boot.

5. UEFI hardware can be used in conjunction with BIOS.

All computers have a BIOS, which is used to load the computer's most basic program code, initialize the hardware, test its functionality, and boot the operating system. The UEFI interface is a conceptual comparison to the BIOS, which is used to automatically load the operating system from a pre-boot environment to an operating system so that the boot process can be simplified and time-saving.


UEFI DualBIOS? Technology
At the heart of this exciting 3D BIOS technology is a pair of physical BIOS ROMs containing GIGABYTE's exclusive in-house designed UEFI BIOS expertise.

In essence, UEFI was created to replace BIOS. In terms of functionality, UEFI's scalability and execution capabilities are far more advanced than the humble BIOS, and the most intuitive way to visualize this is that you can see a graphical interface under the UEFI interface, which can be operated with a mouse, and allows for a much simpler self-testing process at boot time, which is the most basic difference.

What's in a BIOS/UEFI

With operating systems ranging from Windows, to various versions of Linux, to Apple's MAC OS, the BIOS/UEFI is actually designed by different vendors to be a relatively low-level "operating system" (though less precise) that you can understand. You can think of it as a relatively low-level "operating system" (although not quite accurate). Currently, BIOS/UEFI is mainly Phoenix BIOS, AMI BIOS, Insyde BIOS and Byosoft.

Phoenix BIOS

Phoenix BIOS is a product of Phoenix, and the Phoenix BIOS screen is simple and easy to use. Due to the acquisition of Award BIOS (once a very popular BIOS), Phoenix BIOS is now subdivided into two kinds of products, the first is Phoenix Award BIOS, this kind of BIOS product is mainly oriented to the ODM as well as entry-level market products, because of the simple functions and relatively low cost of authorization; the second is Phoenix BIOS/ The second is Phoenix BIOS/UEFI, which is mainly for Phoenix to face high-end desktops and other products. BIOS/UEFI is characterized by powerful features, high degree of customization, and of course, expensive licensing fees.

AMI BIOS

AMI BIOS is the BIOS system software produced by AMI (full name: American Megatrends Incorporated), AMI BIOS is characterized by powerful features, support for OEMs to define more places, and authorization costs are relatively low. AMI's main products include AMICORE and AMI Aptio, the former being a traditional BIOS and the latter being UEFI.

Insyde

Insyde bios is an emerging type of BIOS that is used by some Intel chip-based laptops, such as Shenzhou, Lenovo, etc. insydeh2o is the representative work of its UEFI product, and it should be said that Insydeh2o is the most popular BIOS. Insyde's UEFI products are so good that it has overtaken Phoenix, the industry leader, as the UEFI leader -- many laptops actually use Insyde's insydeh2o UEFI.

Byosoft

Newly founded in 2006, Byosoft is the world's fourth Intel-authorized BIOS company. Its current products mainly serve OEM customers, and are not found in many motherboards in the retail market. Moreover, Byosoft basically focuses on EFI BIOS. In fact, Byosoft still has some connection with Phoenix - its founder is a former Phoenix employee. The famous Xiaomi Win10 tablet, whose BIOS is a Byosoft product.
