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.

Why? Only new motherboards will ship with new version of UEFI, so you can use older ones for whatever you want.
PS And the list of operating systems with UEFI support:
Linux
HP-UX
HP OpenVMS
Mac OS
FreeBSD
Solaris
OpenBSD
Obviously platforms on which these OSs can work support UEFI. You all are just average users of consumer PCs, but for server side of life UEFI offered much much more.
For consumer PCs usage of UEFI permitted much more wide unified modding due to standartization and unification.
As for Secure Boot, I don`t know about yours motherboards but on mine it can be switched off.
Well that is a problem you see,i am using other OS (linux) and older win7(for games) in dual boot.What this news mean is that of 2020 i probably would not be able to do that.

And at that point, you should probably have a different machine for tasks regarding old OSs

I just have impression that these guys think that they loose ability to use old OSs on the fly with their current rigs.

Well i am on older one currently (AM3+
) and i would want little bit more power that means i need to upgrade or in my case buy whole new system,and then there is that pesky stuff about new features meaning new USB,DDR standard,PCIE what ever number it is going to be in 2020 and beyond,that i would like to use.And then 2021 or 2022 or any year after 2020 there is going to be faster processors and host of new features that i would like to use,and if they shut down compatibility mode and don't allow new keys for other OS's what then?? or if mobo mfg. conveniently forget to add option to disable secure boot ( that thing already happen couple times) ??

Yeah, yeah, Mr. SSD_bot, but of course...If I could only manage to sort out bots... Anybody who ever saw an interview with BigBadBilly would know who I mean under the "butterfly" - the guy who waves his arms as if trying to fly out of his chair...
