- Advantech Engineer Florian will highlight the differences between UEFI BIOS and Legacy BIOS and as well introduce some new mechanism possible with UEFI. This gives and good overview for Engineers but also for decision makers.
This ten years old video is the best and most clear explanation about UEFI I managed to find.
In my search "what is UEFI ?" I stumbled upon this video.
Results: I now know a lot more about it! Thank you!
The future is now, but it sent all us back to school. In the BIOS era the issues where in MBR, OS or software bugs. Today, we added UEFI, not as a solution for that.
Very educational video, thanks.
This was not at all painful to watch as some people say, in fact, I found it quite enjoyable. :)
Also it helped me decide on my choice too, which is what I came here for, thanks!
Thank you very much for the excellent technical overview Florian; especially for the links to specification and and especially UEFI programming :)
Absolutely fantastic introduction! you are thorough, clear, informative and precise. Thank you
Great presentation,the thing that the speaker has not English as native language makes it a bit "buggy" ,nevertheless he is giving all the required information(and more than needed) so you can understand the differences,and this is the point of it.
Nice job,thank you.
@Bryan S. I think he means a specification in UEFI being a specification of the implementation. It is true that UEFI and BIOS are diffrent implementations. But UEFI being the specification for manufacturers to make their own implementation.
Not 100% so anyone correct me if I am wrong.
b44rt Ah, I see. Thanks for your input!
Thank you for this tutorial...that is exactly what i was looking...
Thank you for explaining the differences in detail.
Quit trolling and stop making fun of his English. This video is really informative and useful! Thanks for the time and efforts of making it. I'll be surprised if most of you can speak another language as fluent as his English!
Excellent explanation.👍👍👍
Great video. Very informative. Thanks much.
Awesome explaination of the two BIOZ :)
Thanx, the information you have talked about are very useful, and Thanks again Tech support :)
i have sony vaio e series laptop. i cannot change brightness in windows 8.1 and 10, i think it has to do with uefi as it is not supported in my ;lapptop so am i right or or is there any solution. please help.
+Nishant Mishra
download a laptop driver for your keyboard and it will work. Vaio driver support sucks so good luck!
Great video bro...
Helped me out allot with formatting these new windows 8 laptops!
Can anyone please help me with a procedure so i can change my Legacy to UEFI on my Gigabyte GA870A-UD3 (rev 2.1), i am using a AMD Phenom ii x6 1090t Black edition CPU.... i would also like to know which BIOS version F2, F3, F4, F5 for the CPU... gigabyte says F2 ? really is it really that old ? can you also help me create a Rufus USB drive so i can boot and change my Legacy to UEFI or GPT partition...... please i want to be up to date and not use old legacy BIOS........ TIA
That was a refreshing interesting intelligent video, void of all the basic crap out there telling what a hard drive is...
Excellent video - thank you very much.
Good explanation! I would forgive him his lifeless attitude if he could end this lecture with; "Get to the choppaaaaahh" >
He is not entertaining. He is sharing his knowledge.
Thank you for the upload. Great information.
thank you very much, great presentation.
perfect professional lecture
18:17 when was this video made? the lines on the chart become dotted after 2010, but the video was uploaded in 2012
Great work, Florian!
Can I adjust cpu settings from uefi or do in need legacy??
+Aaron Mcbride
UEFI came with the motherboard so the UEFI BIOS and Legacy BIOS functions should be the same if your Motherboard Model supported UEFI.
Most Motherboard came with UEFI BIOS and Legacy BIOS and both supports overclocking.
Thanks very much for this informative video
Great presentation!
Can anyone explain what he means by UEFI is only a BIOS _specification_ and not a BIOS _implementation_? That just confuses things for me. I thought UEFI was a new BIOS, but he's making it seems like it isn't.
+That Random Guyーさん It means, UEFI is only a guideline on how to program the Firmware and not a predefined/finished piece of firmware/software.
I say you're correct because it's a singular present obsolete legacy ;-)
Thanks for clearifying, great work!
Thanks a lot for the information.
I have a question that I hope some of you can answer, does an EFI BIOS still use the CMOS for storing the setings inside your BIOS?
Please how do I do window 7 fresh installation on dell inspiring DV051 with dual operating systems
Thank you. Very well done.
i have problem in my HP 14 touch screen with format and recovery ?
Very informative
Nice information sir... thank you
Damn, thank The Universe i'm doing this shit just as a hobby. Look at this guy!
Can you post links and resources to all the information you just showed? Thank You!
Excellent information, :D
I think is confusing to say "UEFI BIOS". UEFI is one thing and BIOS is another.
+Andrei Marghioala
No, UEFI Bios is the new BIOS vs Legacy BIOS.
UEFI is a BIOS designed for modern way of interacting with the Hardware.
I recently installed Windows 8 on my friend's laptop and i found no way to access the bios setting. Any help ?
Published on : 3-20-2012, so been out a while.
I am having problem installing win7 with USB to a UEFI with SSD drive, any recommendation ?
make certain of your usb settings in UEFI-bios also check to see if your SSD can be seen in the UEFI-bios(you could also apply more secure and safe settings with ACHI-- etc). now when you reboot your PC press f11 or whatever key that allows your to go to UEFI boot menu and select the drive your want to insall win7 on--- not the drive that contains win 7 OS(usb). lemme me if it works... not an expert but had similar problem so i goofed around a little and this is what i came up with... cheers
Mark Gyan As far as i know in order to downgrade win8 to 7 you need to go to BIOS and change UEFI to Legacy, lately with my research i have noticed that only win8 originaly made to for with UEFI Not win7, However you can search the web to edit and modify the boot on the win7 boot folder to fix this issue that i know microsoft has the HOTFIX for it but i didnt bother doing that all i did i changed it to legacy and downgrade to win7
good video
I love you!
Wow, I left IBM (server hardware side) in 2009 and went to work on the server OS side with Red Hat (Linux guy's). My pal worked Intel's Iitanium and we all thought it was a losing technology. But now I see that the UEFI part lived on with Microsoft's Windows 8 and up (I am running Windows 10 on a test server) . When I left Red Hat in 2013 I recall that there was an ongoing discussion on implementing UEFI in the Linux community.
I guess UEFI won? So how do I boot to a bootable Linux DVD and bypass startup on Windows 8 ... smile!
+Dennis Hunter
you can still boot via linux DVD and bypass windows. Come on dude that's a no brainer.
Micro Soft No, UEFI can be configured to NOT allow booting from DVD / USB device. They thought of that one ...
Unclear: BOOT MANAGER (LOADER?) is on the motherboard (16:17)?
afaik: GRUB in Linux, OSL2000 are software, independent of the motherboard.
It is unclear here what UEFI includes: firmware on the motherboard alone, or software of the users choice afterwards.
They better stop building walls around everything.. Because making users unable to install previous versions or other operating systems is kinda low.. It's either that or every computer should include the option to turn UEFI off. >_
Where it cames from? Why does we need it?
Mr. Wohlrab! Do you have any other videos on computer technology like this!!? I really like the way you teach! It would also help if you had animated or just more graphic visual aids ! But please I checked out this channel but I did not see other videos by you ! Can you direct me to a place where to find more of your tutorials!!? Thank you 🙏🏽
Why does we need it?
Hi. My name is Mitch and I'm really really funny.
educational.... but painful to watch!
LOL... be nice!
Now I know what the word "monotone" means.
CAN YOU JUST TELL ME WHY WE DOES NEED IT?!?!
WHY DOES WE NEED IT?
If you notice, windows 8 pressed UEFI hardcore. In fact, some Hardware Manufacturers like HP decided to not even offer a legacy boot option (because EVERYONE loves Windows 8 to death, right?) Ubuntu had to create a UEFI boot version just to be able to compete, and CD/DVD and USB are conveniently locked under legacy boot, in other words; you have to use an archaic external USB cd/dvd drive just to put another UEFI compatible OS on the computer. They are forcibly trying to assert this garbage on a new generation of users, and restrict at the same time the freedom of using whatever you want. It is not the hardware developers job to manage piracy; it is their job to produce working hardware that can be used with a wide variety of operating systems. They need to stop getting in bed Microsoft; no matter how much money lines their pockets, Microsoft only wants to shut out its competitors. More than ever, you will see Microsoft take forcible means with the cooperation of hardware manufacturers to ensure they custom tailor all UEFI based systems to only support Microsoft based operating systems.
Even if the BIOS was 8bit, so fucking what. BIOS just needs a few seconds to initialize handware then it passes over control to the OS. There is no need for any fucking mini OS between the hardware and main OS. Assembler makes it harder for the hackers, C/C++ makes it easier, so what was a rarity, ie bootblock viruses will now be more proliferant and in fact, the hackers will probably compete aginst each other now to make the best bootblock viruses whereas before they wouldnt have bothered.
when was this video made ? 1974 is 25 yo ?
+swizeus
he is the Legacy BIOS in human form
I'll Be Back...
The old bios just worked. Now we have shitty UEFI.
GPT is just plain stupid.
You dont understand UEFI.
Why the hell would you wanna use an unsecure 16bit bios, when you can use a 64bit uefi bios with greater security, faster startup times and room for future growth.
There is no security in UEFI. Go look at the many talks explaining the vulnerabilities.
+muffemod
yeah if you don't understand technology don't freak out and you are making yourself stupid... Believing in gossip is just as bad as blind leading bind.
Anything can be hacked including the Legacy BIOS but it is more likely that hacking your BIOS is a waste of time... If I was going to hack something then I'd rather hack Google, Facebook, twitter or anything that is online than that of your PC's motherboard.

@ 0:50 "who is your daddy and what does he do"
some comments from country bumpkins who think English should be spoken in a certain accent, what that accent is they are not quite sure due to their isolated villages they lived in. South African accent, Scottish, New Zealand, Australian, Jamaican, Bible belt USA. People of the world please stop speaking English you are upsetting these guys making them very insecure.
Stop saying 'UEFI BIOS', what you mean is a UEFI firmware. A BIOS is not another word for firmware, it is a specific kind of legacy firmware.
good content, but you need a little work on your accent, which is a bit extreme. simple hint
: if you can‘t pronounce th, just say de instead of sze . but again, good content 😠
Opchon romz.
Companyies.
Leave Arnold Schwarzenegger alone boys, he was a litte too young and didn't speak good english yet. He speaks it better now,LOL.
Sorry but his lisp is so annoying I could only watch 2 minutes of the video! Looks like the vid does have good info but his lisp annoyed me to the point of clicking away from it!
it is agood videos....
Sounds Like a prataman
why you so upset bro?
Holy crap is this guy brainwashing me when he stares in my eyes?
I, must, obey. must, not, resist UEFI!
Yes, whats the eye candy for? You are only supposed to mess around in BIOS for intial setup and after that you never see it for a long time... And worse, with UEFI there is a real possibility of bricking your PC, that is fucking ridiculous. There should NEVER be any instances where the user cannot access the BIOS/UEFI BIOS menu. BIOS options should never change ie missing F2/F8 DEL options. Stupid..
if you aren't interested in the subject then why are you making a video about it? You are so bored that you're slurring your words and you look like you're about to fall out of your chair. I'm falling asleep watching you.
