Intel is planning to end "legacy BIOS" support in their new platforms by 2020 in requiring UEFI Class 3 or higher.

Making rounds this weekend is a slide deck from the recent UEFI Plugfest. Brian Richardson of Intel talked about the "last mile" barriers to removing legacy BIOS support from systems.

By 2020, they will be supporting no less than UEFI Class 3, which means only UEFI support and no more legacy BIOS or CSM compatibility support mode. But that's not going to force on UEFI Secure Boot unconditionally: Secure Boot enabled is considered UEFI Class 3+.

Intel hasn't removed legacy BIOS / CSM support yet due to many customers' software packages still relying upon legacy BIOS, among other reasons. Removing the legacy BIOS support will mitigate some security risks, needs less validation by vendors, allows for supporting more modern technologies, etc.

    Somebody should take the NT4 leak, or the OpenNT fork (if you can still find a copy online) and add GPT support to it.

    Hell with a bit of knowledge of the code and some injection work one could probably support GPT on Windows XP and the Windows 6.0+ revisions as well, although you would probably need to disable driver/system file signing to get it to work.

    There is literally no reason we can't have GPT bootable M$ OSes on traditional bioses except for microsoft's intentional deprecation, and no reason we can't have traditional bioses providing advanced boot services to GPT partitions so long as there is sufficient flash space for option rom boot service code.
