	Yes, I agree completely!

	It's absurd that in plain XXI century, hardware makers still
default to legacy mode without a chance for the user to change that in
BIOS.

	I understand that Linus Torvalds complained about EFI some time
ago (http://kerneltrap.org/node/6884), citing it as "other Intel
brain-damage" but at least EFI would give a chance for the user to
interact better with the system than the limited, ugly and old "BIOS".

	When every motherboard maker adopt EFI, I hope this limitation
will go away. I can't understand why new Core i7 systems still use BIOS
instead of EFI.
