BIOS (Basic Input/Output System)

BIOS (Basic Input/Output System) is a set of firmware that implements APIs for working with a computer and devices connected to it. BIOS refers to system software.

2017: Intel Plans to End Support

In November 2017, Intel announced the timing of the BIOS abandonment. Instead of this firmware, the American corporation will promote its set of EFI specifications.

At a regional event for PC and motherboard manufacturers, Intel representatives announced the rejection of backward compatibility with the legacy BIOS mode in the microcode of laptops, motherboards and servers, starting in 2020.

By this time, the UEFI version will have improved to the third class, which does not provide compatibility with the outdated CMS boot mode, and will have to be supported by all computer and server platforms.

BIOS Settings

By 2017, computers come with UEFI, but many of them are also equipped with BIOS to use outdated hardware that may not be compatible with UEFI. For example, older video cards may not work on systems using UEFI.

Intel's failure to support BIOS means that you will not be able to download a number of classic hard drive utilities and update the BIOS using traditional methods.

According to Intel, a complete transition to UEFI Class 3 will increase the level of security of computer systems thanks to the constantly active Secure Boot function. This mode is not mandatory for PCs, that is, users will still be able to run unsigned Linux distributions through UEFI. However, it will not be possible to bypass compatibility problems using CSM on devices with Intel processors, Liliputing notes.

After abandoning the BIOS, support for 16-bit operating systems and 32-bit Windows 7 will cease. Intel will eliminate components without UEFI support, ensuring that drivers, peripherals, and utilities can run without CSM.

 Ultimately, the use of PCs should become safer, the amount of code will be reduced , and new technologies will receive wider support, summarize in Intel.^[1]
