Dont ruin the joke
Great way of explaining it lol.
Thanks for putting this video together. I learned something new todsy
*opens hard drive*
“Wait, you can’t smash software?”
By hammer
You can smash the hardware to get to the software.
Fuck you made the joke before me. Oh well i wont delete it
Big brain moment
Well if you opened that hard drive it will kinda *smash* it for you if you know what I mean

UEFI... we were calling this "Yoo-fee" at my job.
*You-fee
@@aretard7995 I say "oofie" but in IPA it's "ooh-effie"
I say you-if-ee
Where did you work? I want to know where to crash in with my trap car, because this is blasphemy.
If you're a fan of Final Fantasy 7, it's pronounced Yuffie.
Usually the "as fast as possible" videos are loaded with new information and I like them. This video spent way too much time explaining a traditional BIOS and barely touched on UEFI.
true
Nobody uses uefi that's why
That's because it's the same exact thing with a different name as far as any consumer is concerned.
... because the UEFI is BIOS evolved...
Well, you can't get any better in explaining the bios and UEFI basic concept on how Linus explained it. Linus's only job was to tell you the concept on how the bios works. If you want to know how to set up detailed bios or UEFI settings. Go and put on your reading glasses. Find and open up the MB manual and start reading the bios section of the manual. Stop crying like a little baby
I don't care what anyone says, I'm going to still call the UEFI the BIOS. I've been saying for over 10 years, not stopping now.
bob bobq sorry bro im lazy
+Robert Williams I prefer to call it UEFI if my boot disk is GPT. BIOS if not, even if UEFI is booting the MBR disk.
Industry insiders and people in the know still call it the bios as well.
Same here. Had quite a discussion with a shop assistant.
lol i hear you man !!!myself I dont know why I still call it BIOS
This dude makes everything much more easy to understand, like the teacher I wish I had at school

1:15 when the bios are just right
Your profile pic is just perfect for this.

Can you do one on the actual BIOS setttings too?
Okay. But it's an important aspect of building a computer right? I have no idea what a lot of the settings in my bios means and it would be useful to know for overclocking. If he can't do AFAP maybe he can do one on his main channel.
+Victor Nguyen I don't usually refer people to the RTFM rule, but in this case your motherboard manual probably does have a section on bios and what the settings do.
Awesome I'll check it out.
+Victor Nguyen google
+Victor Nguyen For just basic computer usage, the only thing you really need to mess with in the BIOS/UEFI is the boot order. For overclocking, your best bet is to search UA-cam for overclocking guides. Linus has some as well as many other popular PC centric channels.
For the harddrive stuff ... I'm sure you meant GPT vs MBR. You can actually boot on a legacy BIOS system into a GPT disk much larger than 2TB. UEFI has nothing to do with that, it's a means of having better controls over newer hardware like PCIe.
UEFI itself doesn't define the partition table on the disk. That's after the BIOS/UEFI started, once it's read the disk's first sector. Then either MBR or GPT tells it where to go to find each partition on that drive - in order to search for a bootable partition.
GPT did become more standard around the same time UEFI became standard. And older BIOS systems did have incompatibilities with it, though not newer variants. If you have a UEFI system (very likely if your computer is from within 5 years), then it can make use of both MBR and GPT drives. If your computer is an old legacy BIOS from more than 10 years ago, it might not be able to use GPT. But in between those the BIOS (even if non-UEFI or a UEFI set to legacy mode) both MBR and GPT would work fine - a bit fuzzy cut-off as the motherboard supplier needed to adjust some things to make it work.
Man invented GPT disks 3 years before GPT was born
Yeah this video didn't really explain UEFI. I haven't seen a single video on UA-cam that really explains what it does.
Techquikie is a very good channel. I know most of the things they show, but still I love to watch their videos because of 2 reasons : 1. There can be something which I might not know, on every topic. 2. Linus hosts in these videos. I love Linus
remember when we had to use ribbon cables and place the pins behind our hard drives
+psp785 i miss IDE
+FunWithTreason eh Sata is way better cuz if you have extras then you can strangle people with it :) try doing that with ur pata.
+psp785 One second, need to change my drive back to master
+psp785 I hated IDE. The Molex connectors on those were always a disaster to work with because if for whatever reason you put the power connector on wrong, it would fry your hard drive.
+Siknik64 Never had that problem because all the molex connectors I've ever use have been keyed with the angled corners, would only go in one way, you really must have forced one in to get it the wrong way.
The blue screen days of bios were the good days. They all had quick and easy controls where I could mash the correct keys in the correct order very quickly to browse through every setting in no time at all. Then came the fancy animated graphic BIOS. Many things now require extra keyboard key presses, take longer to respond, or in one very odd case I found, actually required a mouse to access some settings.
I'd be enthralled if I could have those old blue BIOS screens back. I hate it when "upgrades" are actually downgrades that make something slower and/or more clunky for no good reason.
I have used uefi that looked like bios, that’s the best version
UEFI is not just BIOS+GUI+Big Storage support. In reality it's a giant piece of bloatware. It's increases the system attack surface with the OS unable to mitigate it (and yes, there is malware for UEFI and your vendor probably will never patch the vulerability).
Furthermore, UEFI is a Microsoft standard and it's not sandboxed. So now, Windows Update will not only ruin your OS, it can also break your firmware.
@@RicardoLuna oh so many times i had to reinstall grub because i had to hop on windows 5min and it fucking deleted the linux boot from the boot options
Not sure about modern computers. But in the past, the BIOS chip was directly connected to the address pins of the CPU. The power button sent a signal to power on the CPU. The CPU read the 1st address (whose data comes directly from the BIOS chip). Then the CPU executes those instructions.
In other words, the BIOS is the first code the CPU runs when it is powered on...
And that code dealt woth some quick hardware checking and then searching for a bootable drive.
If a bootable drive was found the BIOS starts executing the code stored in the drive's boot sector (which is stuff like the windows loader).
So that is how a pile of metal was able to boot at all: The CPU starts by reading and executing the BIOS code, and without that BIOS code (the "first instructions" telling the CPU what to do), it wouldn't be possible to make the computer start at all.
3:40 there was the little known American Megatrends "Win BIOS" from the early 90's that had a gui resembling windows 3.1 and had mouse support. later versions of that bios had animations but were very limited.
(edit)
i think some IBM PS/2 Systems had a gui bios aswell
I'm using a 2009 American megatrends bios but it doesn't have mouse support

I still remember when 1GB flash drives were common in 2006. 2GB was rarer, and 4GB was "wow, do you really *need* that much storage, or are you just showing off?".
I love your videos! I can't help but keep noticing Linus either reaching for his phone or his microphone transmitter. He does it all the time, and its cracking me up.
Some add on cards can also have their own BIOS. Generally the motherboard BIOS goes first all goes well it scans expansion slots for BIOS and executes those. Generally cards with their own BIOS are related to storage controllers like SATA controllers, SCSI cards, or some form of hardware RAID.
Graphical interfaces are far more common with UEFI systems. However a BIOS is not limited to the typical blue Phoenix-style BIOS that we all know and love today. I had an AMI BIOS back on my 386 which featured a graphical interface. It was certainly ugly as sin, but it had faux Windows 3 menus and was mouse driven. Which was impressive because when trying to play Ultima 7, I always had to choose between running the game or loading a mouse driver. 640k of conventional memory sucked, and I never understood games that refused to run when EMM386 was loaded. Damn boy! I got 16MB of memory! Let me use it!
Michael Bellerue its because you have 16MB of ram
Blaze King a *really* long time ago
Hey Mike I have a surface book with UEFI Firmware and want to do a factory reset. Can you give me any tips?
Phoenix-style BIOS with blue color? It originated from Award Software, used up to Award Modular BIOS 6.0PG (and in 4.51PG with the change color function). Also it is used in the generic Phoenix-AwardBIOS 6.00PG. There are some exceptions: some ASUS motherboards have a AwardBIOS with a Phoenix-style interface, and a Phoenix-AwardBIOS 6.00PG with a Phoenix-style interface.
I just got into this because I wanted to hear how UEFI is pronounced in English (and apparently there was not a common agreement yet)…
But you video is great, with lot a wonderful examples that I would reuse, eventually, to explain this (apparently) complex things but conceptually they are as common as you explain!
Thanks a lot for this share!!!!
This guy is just great helped me through my first build
I'm too poor to afford a bios on my raspberry pi.
lol Should be good. ARM architectures don't use BIOS.
+Andrew Powell sort of. It still has a basic input and output system, it's just different to a larger computer's BIOS.
The Freebooter Are you referring to a boot loader program? As far I know, BIOS is particular to IBM-based systems. Running a Linux kernel on an ARM system requires a system tree because the BIOS program doesn't even exist.
+Andrew Powell the trademark is only on IBM machines, but the one in raspberry pi is so close to being the same it might as well be.

Oh yes, jumper settings, I remember them well! I also remember all the hair I had back then when I first began messing with jumper settings on motherboards!
I remember the jumper days. I still have a 486 SX25 in the basement and a Pentium 200 MMX that still runs (Windows XP)
Thank you for making these videos. Very helpful! Keep it up!
there were a few graphical traditional BIOS implementations. see AMI winbios and dells from about 2007< (eg opti 780)
+s8wc3 back in the late 90's my high school's Computer Network Technologies class had a bunch of Gateway machines running Windows NT with AMI bios that had mouse support, but it was PS/2 Mouse, and keyboard only, no fancy USB lol!
Commodorefan64 yeah lol, those were probably 486's, long before any USB!
+s8wc3 No they had USB 1.1 but the graphical Bios just did not support a USB mouse, or keyboard, and where Intel Pentium II machines If I remember correctly, this was in the windows 98/98SE era, and my school had just built a whole new computer lab with all new Gateway machines.
Commodorefan64 Oh cool! I always thought that bios was more for 486/early Pentium than P-II.
Great, thorough explanation, as always :)
If you remember the jumpers and master slave on mb and hdd then you hade a pretty fun childhood :D
The good ole days!
I have a tiny box full of jumpers!
I used to install 20mb hard drives in Amstrads & formatting hdd through bios and using fdisk for partitioning. Youngsters these day's don't know anything about DOS.
I remember master slave.
I don't miss ISA conflicts.
Actually there are BIOS based systems that have GUI BIOS screens that support mouse input. The old Compaq Pentium systems did. The BIOS had to be booted into with a floppy disk that contained the code. There was no other way to enter the BIOS.
Linus made me remember the jumper "times", still having nightmares for those mobos!
Yeah I had that issue with my million Peta-byte hard drive, but now I can even put it in my laptop.
Zettabyte drive!?
I'm old enough to remember using the old style blue bios on some computers that also had Jumpers for some basic stuff like the CPU multiplier to allow for overclocking, or using jumpers to clear the CMOS incase you messed up the CMOS settings, or you accidentally put a password on your bios (or you got a computer with a password on the bios).
While modern motherboards usually reset them selves after a bad overclock or bad bios setting, I still find that some things are irrecoverable and still require removing the CMOS battery and clearing the CMOS with jumpers, but that could just be because I have a cheaper motherboard (the ASUS M5A97 R2.0)
There was still a software BIOS on a ROM (flashable and it’s memory has always been dependant on a battery, to this day) back when you had to change settings with a jumper
I’ve played with 286/386/486 systems then into Pentium 1’s
Even super socket 7 used jumpers for FSB clocks and over clocking -
All of these still had a BIoS

kids these days dont know what a beep code speaker is. partly because most motherboards dont come with them anymore
The case manufacturers usually pick up the tab, although I've seen some motherboards without the pins needed to drive them. The PC speaker (not beep code speaker) is far from dead.
jeffjoraj
i have a sabertooth x79 and carbide 400r. it was 350 for the board and 120 for the case. 470 bucks doesnt warrant including a 7 cent beep code speaker/pc speaker/internal speaker/mobo speaker/whatever the fuck someone wants to call it speaker?
EZOVERDOSE
Damn dude, that sucks. I got a wicked cheap case from Micro Center and it came with a speaker. Guess they only come on the low end?
Also, I called it the PC speaker because that's what it has been known and documented as for the past 36 or so years (first found in the original IBM PC). Back then, it was a real fucking speaker.
jeffjoraj
times have changed. theyre only used for beep codes these days
+EZOVERDOSE If you're lucky you have a motherboard like mine that has an LED Post code display then the beeping way of doing it is obsolete.Sadly you mostly only get the LED displays on Premium/OC boards.
That little speaker comes with your case most of the time and the picture you shown always come with the case!!!

+Daniel Reimer Looks more like a Manji, the traditional Chinese symbol designating a temple. Note that it "flows" clockwise, rather than counter-clockwise as a Swastika does. Considering the Manji represents a temple, it seems apt.
+srgpepper42 I think you mixed up clockwise and counterclockwise. A Swastika is clockwise, a Manji is counterclockwise.
+Daniel Reimer Its an Intel socket so that explains it.

So I converted my disk from mbr to gpt with ao mei and booted successfully, just remember to change the boot mode from BIOS to UEFI, that's the point
Thank you for your easy to understand explanation!
mbr is still good to use, I mean it has advantages that gpt doesn't have
what advantages? that it supports windows xp ?
Anyone else remember the really old BIOS's that actually had a GUI with mouse support?
so sad was with only keyboard :D
I had a laptop last year which went to the BIOS, which had mouse support.
My Fujitsu T730 has *partial* mouse support during bootup, but if you go to the settings, it's back to the nasty blue screen.
My MSI motherboard, on the other hand, has a broken UEFI interface.....
Old IBM thinkpads, the cursor is a duck flapping around. I love those machines.
of course, as usual Linus is wrong. UEFI has nothing to do with having a graphical interface. It can have one and most modern versions do, but that's not the real purpose behind UEFI. The truth about UEFI is that it's a problem searching for a solution. UEFI is a derivative of EFI. EFI was invented by Intel when they want to switch everybody from x86 architecture to IA64 (Itanium) and kill off legacy x86 support. Ia64 can run x86 code through emulation. However, Ia64 was not an x86 processor and doesn't start up in x86 real mode with backward compatibility to an 8086, the way all x86 processors do. Therefore for a PC built for an IA64 processor, x86 BIOS would not work. That's why it was necessary for Intel to develop EFI. However, things didn't exactly go as Intel planned and the world decided they weren't ready to ditch x86 for IA64. Then AMD introduced x86-64 and microsoft made a 64bit version of XP to utilize AMDs x86-64. At that point Itanium and IA64 was a sinking ship and doomed to the scrap heap of technology. But EFI lived on and became UEFI.
And Linus is wrong about MBR also. MBR is not really a BIOS limitation. It's a Microsoft limitation imposed upon us by the same company who once asked "who would ever need more than 640k?". The BIOS simply looks at the boot sector of a disk, which is the very first sector on any disk. It looks for a specific string value in the first couple of bytes. If that string is present it assumes that's a bootable disk. It then loads that bootsector into main memory and jumps to it, handing off control. At that point it's the bootsector code and the operating system that loads that controls EVERYTHiNG. So any limitations are NOT the fault of BIOS at all.
Great way of presentation ! Thank you!
Never thought Thechquickie would ever have an uninformative video but there's is one now
Like this whoever are still using BIOS these days. At least i won't feel i'm the only one to.
I Do!
Fast-forward 2020
Still stuck with BIOS/LEGACY 🙄
I'm updating soon as Intel supports PCI 5.0
I have a PC with BIOS and the PC I'm using rn uses UEFI
My computer supports UEFI and legacy but I’m thinking of switching back to legacy I switched over because I wanted to change my boot logo. But my hat drive is 1tb an I don’t care to have extra partitions. I think if the bios chip runs some of the functions that’s good
I still hate UEFI. I hate that I have to use it to go past 2TB.
On Linux you dont need UEFI for GPT ;)
is it something that UEFI tick you off, I've been using it for at least 2 year now...
care to know why? :P
He hates it cause there is no reason for it. It's proprietary and not like Microsoft proprietary but scumbag intel proprietary where you get binaries and no source code for their hardware. Let me correctly summarize what Uefi really is. It's basically bios and does the same exact thing as what bios did. It's firmware for you cpu. Cpu powers on runs some intel top secret micro-code and then executes first instruction from 0xFFFFFFFF0h which is typically spi flash memory address containing first line of bios. Uefi is just bios but really over structured. Alls bios build a standard table which Microsoft, Linux, and Crapple have agreed upon which list's essentially address for basic functions the os needs to operate the hard disk to load their own drivers (more firmware but specially designed to run with the os's peculiarities). So basically bios and drivers do the same things. They are firmware which do specific things and the o.s. is generic cause they don't want to write code for every single kind of motherboard that exists. Instead the motherboard company writes the specific drivers and bios.
In early times pc's worked differently than they do today. The bios never stopped running and the o.s. would have to translate everything to bios and have bios do it. Eventually windows decided to have drivers which ran natively, this greatly increased performance and has been this way ever sense. So bios only runs when computer turns on and that's it. It really doesn't matter bios or uefi to the end user cause it only runs for like 10 seconds until operating system's boot loader takes over. If you think firmware is negatively effecting something that would be a driver issue not bios.
Uefi was developed by intel and is essentially bios but also turns bios into the o.s. It basically is bios which then runs as a primitive operating system which then loads another operating system. It has drivers etc. When you develop a board you only have to write drivers for various components like ram, and other non volatile storage, pci bus etc. instead of writing the entire bios and the o.s. interface and matching it you just write a component drivers for the pcb topology and uefi takes care of o.s. socketing. But the problem is you still have to do ACPI asm and by sectioning you off from a lot of the work you no longer have the same capability for extreme stuff which wasn't thought of by intel. basically you can only continue to produce the same motherboards other companies are producing because you have to rely on intel binaries and you are only writing the drivers. You can adapt Linux or windows to an extreme platform because that was done by intel in Uefi proprietary binaries. So you can't even use uefi for anything other than cookie cutter mobos.
marshalcraft Why would you want to run UEFI on anything else than a cookie cutter mobo? Are you soldering your mobos yourself?
This whole time we have been talking has been to the platform designer, so while we aren't soldering the pcb's ourselves we are paying someone too. Why would you even be here unless you were pcb designer? If you are typical end user then you don't know what uefi/bios is other than short burst of text when your pc turns on.
Great video and really well explained. Thanks mate!

Actually, there was bios in PCChips motherboards that looked like Windows 3.1... with mouse support
+MP-Tuners Productions I remember those, and Gateway in the mid-late 90's had a few various machines with AMI, and American Megatrends Bios that had support for PS/2 mice, and keyboards, and know that for a fact because my high school's Computer Network Technologies lab had them, and I remember playing around in the AMI ver, and setting all the machines to a 100mhz overclock with the mouse, and man did it spin the system fans up lol!
+MP-Tuners Productions
yep, there was nothing wrong with the old BIOS, the UEFI shit is just the first step to take over the PC open arquitecture... because really? not being able to handle more than 2 terabyte drives? so what? you are not going to work with only the BIOS, you only need it to boot the OS, then the OS will handle everything, lack of GUI? that wasn´t the BIOS fault, there´s wasn´t enough space in the old eeproms to make complex GUI, with new flash memory you can have a bios as large as you want, rom space is no longer a constraint...
Yea, many AWARD bios in the late 486 era had a Win31-ish interface with mouse support
+Omega Rugal So what if you have something like an ultrabook with only 1 drive that is 4TB large, and the bios can't find it because it only supports drives up to 2TB, then your screwed on getting it to boot no matter the OS you are using, so yeah a modern UEFI makes since.
+Commodorefan64 It will boot but you could only use 2TB.
"Adazh?" That's a pronunciation I've never heard.
There were some 486s motherboards with a graphical user interface, with icons and mouse support, long before UEFI existed. I wonder why that didn’t catch on and in fact went back to text interfaces

Seems like its always a total PITA getting a UEFI system to boot off USB... :S
I just spent 2 houes trying to boot a usb on uefi.... pain in the ass

Lately, I've been having much issues just trying to boot from my DVD drive, and that used to work just fine before. Same BIOS, same DVD drive, same disc (same OS), same BIOS firmware (never patched), ... But I have no clue about UEFI or that other thing. I'm sure some setting is off. BIOS's are still a pain, lots of weird parameters ...
Hm not sure. Bios i had on older asus board was f8 for boot menu, now on asrock uefi board its f11 for boot menu

want to set my computer to game while streaming at the same time
I liked how this guy squeezed in the ad on freshbooks while trying to talk about BIOS and UEFI *as fast as possible*
my motherboard says press f1 to enter uefi bios setting
and i wonder do i have a bios or a uefi
DiamondFace the problem is, all motherboards have a firmware: either a BIOS firmware, or a UEFI firmware. Some people started using the words 'BIOS' and ''firmware' interchangeably but that doesnt make sense as not every firmware is a BIOS firmware. Stop saying 'UEFI BIOS', it doesn't make sense. Yes some OEMs even do this but they are wrong and only complicate things.
You have a uefi. Uefi was made to replace bios, but they keep the name for all the folks who are used to calling it bios so they don't get confused.
0:00:00 you mispronounced adage, really mangled it
I *Know!* What was *That* about?
Everyone knows that it's pronounced "ad•age". This leaves me to believe that he's either reading from cue cards or plagiarizing something.
He has a Canadian accent sometimes. It comes out every now and then lol. Not saying thats what it was, but could have influenced his pronunciation lol
@@davidfoote696 Oh crap. 4 years? I've had this account for four-frikken-years? Where does time go? BTW, yeah, he was trolling with the pronunciation. What makes me trend that way? _This account was created to troll._ Just sayin'
O.... I remember the old jumper method for setting things like the FSB, and the like. I don't miss that.
Pls do a tutorial on how to open the bios on various computers please.
"You say adage I say adage...."
I wish Linus would do A+ Certification videos...the ones I am watching make me sleepy...
A more technical explanation as to why BIOS/UEFI is needed: Current computers still follow more or less the Von Neumann architecture, which states that the CPU fetches instructions from a memory (RAM) and deposits results into it. The problem is when the computer is turned on, the RAM will be empty or filled with garbage values and there will be no instructions to tell the CPU where it can execute the bootloader that will then boot the operating system. The BIOS states that the bootable code should be in the first block of the media set in the boot preferences. UEFI instead uses a partition on that same media set to boot.
The BIOS/UEFI kicks in in order to populate the memory with those procedures (as well as perform some hardware checks) and then it passes control to the bootloader. Well that and it also probes what hardware is connected to the computer. The BIOS/UEFI being the equivalent of an ignition system is a very very good analogy. Well done!
Right off the bat, this guy is a real life Mikey Day (SNL) character. That's a compliment, Mikey Day characters are always gold. I'm also studying for a CompTIA exam and greatly appreciate this video.
Oh man, and the hand gestures! This guy clearly had some kind of training in presentation. Maybe theater, improv, advanced public speaking. He knows how to speak with his hands 🤌
I pronounce it like Yufi... y'know, FF7?
Sometimes I think of starting a business of my own... Then I think of the paperwork and taxes, and I forget it :|
+HBMHD BUT NOW THERES FRESHBOOKS!!!
Justin Passfield We should get money for that lol.
Lol
If trump can do it, so can you
GREAT! you made me think of it and now my heart is beating manually.
You're an excellent educator. Would you consider creating a training program for A+ certification students?
I always thought it was built in OS hahahaha 😂
Me too! Even if there's no Windows (or MacOS, or GNU/Linux), the BIOS is still there, and it was shipped with the computer when it was originally assembled. So 'Built-In Operating System' totally makes sense.
Why block out the car logo?
+Hank Hill copyright reasons
+Pyroblock (SPG) ^^
Because the car has its rights. It doesn't want to be seen naked on the Internet.
+Toon M lol
maybe because some people may think that they pay for him
really useful and informative. Loved the video.
These videos are excellent. Thank you
