Intel Halts Certain UEFI BIOS Class Level 2 Compatibility Modes In 2020

Intel Halts Certain UEFI BIOS Class Level 2 Compatibility Modes In 2020

Intel will halt UEFI bios compatibility class 0, 1 and 2 support in 2020. From that moment onwards only UEFI class 3 will be supported. This means that Intel platforms cannot boot through the Compatibility Support Module mode, and that's a problem for dual OS boot systems.

Intel this way pretty much halts the traditional legacy BIOS support. The CSM provides additional functionality to UEFI. This additional functionality permits the loading of a traditional OS or the use of a traditional OpROM The news reached the webs though Brian Richardson, a developer at Intel. Recently he held a presentation on the topic at the UEFI Plugfest in Taiwan, reports tweakers today.

According to Brian the compatibility mode is still here as people want to bypass say the secure boot method, or have multi-OS boot settings. An advantage to discontinue the CSM support is that it will make room in the firmware for other stuff, initially, the BIOS would get significantly smaller in file-size. Also security-wise, the step would make a lot of sense.

Starting 2020 Uefo Class 3 will be the new standard at Intel, with secure boot enabled.

@mbk
The Evil Empire, widely known as m$ is trying all that is possible to prevent/discourage people from using op systems other than window$ (and the "old", "obsolete" win versions too). One of the deceptive strategies is to persuade hardware manufacturers (that is, twisting their arms, bribing etc.) to come up with such "inventions" that would prevent (or make it more expensive) the use of, say Linux or/and iOS, as either only or primary or secondary OS within the same PC where window$ resides. Another benefit (for the Empire) is to make so-called cracking harder to implement (under a pretense of being concerned with the software's "safety").
Why (you may wonder)? Because that miserable, butterfly-looking pickpocket who owns m$ got obsessed with the idea of ruling the world, that's why...
