Q:Does UEFI completely replace a PC BIOS?
A:No. While UEFI uses a different interface for "boot services" and "runtime services", some platform firmware must perform the functions BIOS uses for system configuration (a.k.a. "Power On Self Test" or "POST") and Setup. UEFI does not specify how POST & Setup are implemented.


Wait - what?

Not sure what we're even talking about anymore.

If you have non P67 mobo but a k chip you get the better IGP but you can't overclock with the multiplier only with turbo. Which is the same for non k series (multiplier no/turbo yes) chips on either board - except the k series has the better IGP.

Whats going on here?
From my understanding previous Intel generation Speedstep allowed disabling AND OCING, but the SBs don't. On my board I can disable speedstep if I want. You have to have Turbo on to OC. The other thing to consider is no base clock manipulation. These SBs overclock so well, but I think this line is aimed too much at consumers and not enthusiasts. Do enthusiasts really overclock with straight Multi/Volts or do FSB calculations? I think they do the latter.

UEFI is supplementary. It is not a BIOS. It's like a virtual BIOS.

Well it depends...

My old AM2+ board couldn't support over 286 fsb, so I was limited by what my ram could do - what my nb was on different multipliers - and where they'd all meet up.

I found it much eaiser to use a lower fsb (210-225) and just use my unlocked chip to nail everything as close to maxed out as possible.

In that case I had to buy the 1090T because I wouldn't have been able to even hit 4Ghz on either of the other two locked multi x6's.


Do I like having locked chips and being restricted to multi only? No, not really... but what choice do I have? A 1366 build would cost me more, and wouldn't perform nearly as well - locked chip or not

Well, dislike uEFI already and Ive only been reading it for an hour or so. First of question comes in my mind "What else can you store to protected data".

-DRM
-Operating Systems Bootloader
-New kind of game protections ?
-Identification and personal information risk is higher and anonymity loses it's meaning.
-Unknown threats (Virukses ? -> Totally invisible to user botnets, DDOS = sure way of the future, 24/7/365 machines total control -> attacks = high server risk)

Seems this system is build not to boot fast or support new hardware, but as very intelligent Copy Protection for future software and operating systems. Funny enough the actual facts of the code are hidden in private documents and no information is given to board manufacturers to simply use regular BIOS.

Booting fast? yes, but by what cost (and did it actually boot any faster for example that ASUS video on page 1 there's still 2 load modules before OS, heh), if a person/nerd like myself could write any of above examples there's 100 times more intelligent persons on web even more on gaming industry with their DRM I would consider this as extreme high level threat of today.

-edit-

Here's a pretty curious article / PDF to start with:
http://csrc.nist.gov/publications/dr...47_feb2011.pdf

but this lists and takes under consideration only half what I listed as possibilities of how to use this new 'hype feature which improves speed and yet is slower'.
