[coreboot] About Paging, Realmode and what is going on

[ingegneriaforense at alice.it]

Hello everybody,

following the mailing list about the questions posed by Philipp Stanner I read:

"Why does every modern CPU still start in RM?

Many industries run on DOS. Many system developers have created
in-house BIOS extensions. x86 will never fully lose its 16-bit legacy."

I'm agree with this answer, and I also understand that some legacy MUST be maintained for the backward HW compatibility, as Zoran explains.

However i wonder if  is there the possibility that Coreboot boots directly and exclusively in protected mode. Is it configurable this behaviour in coreboot ? That is: is it possible avoid the x86 boots in Real Mode, "forgotting" to be compatible with old hardware ?

Best Regards.

Vincenzo.
