UEFI to replace BIOS in most new PCs by 2011?

article published on 4 October, 2010

The basic input/output system (BIOS) used in most shipped commercial PCs is way past its use-by date according to many within the industry. As computer technology improves, some problems can arise due to the continued use of BIOS, such as drive size limits. For this reason, the industry is moving increasing toward the Unified Extensible Firmware Interface (UEFI). "Conventional Bios is ... [ read the full article ]

It doesn't mentioned if the "handful of seconds" with UEFI is using SSDs or not. If it's not than an SSD may reduce that even more.

Considering how fast technology has advanced over the past 30 years I'm surprised the BIOS wasn't replaced sooner.

I agree. Many of the new computers we ordered have UEFI in them but the old BIOS has been stretched beyond it's life. I guess it was cheaper to use that and for most set ups it fit the need but it has reached its limit for many things.

the UEFI will be used before a HDD boots the OS, so off a chip on the mobo. SSDs wont come into play.

You are both right, I was thinking the OS had to be booted from a HDD/SSD which doesn't appear to be the case with UEFI.

This guy is full of hot air, and he is going into a whole bunch of redundant detail about nothing...he is like one of those guys that says, "No, that is not a motor, it is an engine" This is a tiny, behind-the-scenes change. We will still see bios setup menus that look virtually identical...they may say "press F10 for EUFI setup menu", but it will be the same thing.

"For consumers, the biggest noticeable change would be the start-up time of the computer. "At the moment it can be 25-30 seconds of boot time before you see the first bit of OS sign-on," he said. "With UEFI we're getting it under a handful of seconds.""

What he is talking about here is not the actual sign-on prompt, but when you first see the windows loading screen, or actually, when the windows bootloader gets called. Yes, this can be over a minute on some machines with lots and lots of complex devices and staggered hard disk starts, but most PCs already do this in a handful of seconds. This really isn't a speed change, as EUFI will still need to detect drives and run the setup routines for any cards that may have drives...otherwise the OS can't replace bios functions because it can't load.

"Drive size limits that were inherent to the original PC design - two terabytes - are going to become an issue pretty soon for those that use their PC a lot for pictures and video,"

Those who still have PCs that only support 2TB and smaller drives probably won't rush out and buy new drives any time soon; these systems are ancient.

"He said that creators of the original BIOS only expected its lifetime to extend to about 250,000 machines. "They are as amazed as anyone else that now it is still alive and well in a lot of systems. It was never really designed to be extensible over time.""

Those people also thought that only universities and huge corporations would have computers, and that 250,000 machines would be the world supply for the next 50 years.
