  • Looks like a few people read the title watched the first 10 seconds and commented,. telling you exactly what happens later in your video.. (like you didn't notice it),... doh!

  • oh mate I had forgotten how big the bios chip was before 10+ years !!! :D

  • You should have mentioned that this is the first step of one of the ways to burn a new BIOS chip using a working PC...

    People sometimes do this when the BIOS chip is corrupted while re-flashing it for example when you trip over the power cord before the re-flash is completed...

    The way it works is you remove the working chip then you put in a dead chip and re-flash it with whatever BIOS you want on the dead chip to make it work again

  • hahah, that's not a big deal after windows using it's own IO routins.. but after rebooting you wont able to use the PC without bios..

  • The objective of the bios is to configure the hardware on your ocmputer before the os boots!

    once the os boots the computer is no longer using the bios chip you dumbass try to boot it without the bios chip instaolled and you wont get nothing cause the computer will nto know what to do before the os boots and take over the computer

  • Hahaha. Good joke. This is better video ever in my life!

  • Wow its amazing to see that the bios is almost being working for starting the computer

    Lol and all the rest of time it pumps 0.015 volt for nothoing in return lol

  • Damn I have a old motherboard from a pentium mmx & doesen't have a bios , only some similary cip on the video card worked ok on a 350W but doesen't work with a 450W psu.

  • ehm mate, the bios is active only when u start ur pc and while doing the memory reading ect...

  • Most modern BIOS chips ate surface mount now.. thus soldered to MoBo.

  • @mabvsfd Yeah. Just about any prebuilt OEM Pc from Dell/HP/etc uses soldered bios chips, but most custom built machines today (from my experience) use replaceable bios chips. My budget Biostar motherboard I bought 2 years ago has a replaceable bios chip. It's about 1/10 the size of the chip featured in this video.

  • Interesting.

  • Cool though.

    This is normal behavior. Traditional BIOS just perform POST (Power On Self Test). For POST BIOS runs only during power on / boot time. Once system boots to OS there is nothing done by BIOS code. hence the above behavior was possible.

    Modern BIOS, esp high end WS/servers have BIOS not only to perform POST but also some OS/runtime activity like system management (errors handling). Even in this case 99.9% the BIOS code is copied in to memory in memory, so it can still be possible.

  • Now you can insert a blank chip and flash Linux to it and boot your pc in 3 seconds (if coreboot supports such an old board)

  • you can do this because on post, all the data in the bios is loaded to the memory. bet you want restart it.... beep beep beep beep

  • dude. get linux.

  • bios chip is read only it need only for the boot up....

  • Lol a 500 mhz processor? OVERCLOCK THAT BIATCH!!!

  • the bios job is to start the pc not run the pc so once its done its job its not needed of couse it will keep going

  • This trick can be used with Uniflash to make a ghetto Flash programmer.

    You don't actually need to use an identical board as the one you're trying to recover. If you look up the pinout on most DIP Flash chips used on motherboards, you'll find most of them use the same pinout and can be interchanged. It's always advised to look them up first though to make sure.

    Doing this with PLCC's is more tricky, and some of those run on different voltages so that adds another concern.

  • thats what we did with duff chips after a failed bios firmware upgrades, hotswap them so that the failed chip could be re-programed on a working system...

    ahhh.. the good old days :)

  • I just love you computer, You don't have you 4 cpu power connector connected to your motherboard.

    You have to connect two of those wires so it can start up.

  • Comment removed

  • Comment removed

  • the bios isnt need for operation of a computer though, its only to really start it and tweak shit.

  • WHY?

  • interesting

  • dude restart your PC without the BIOS chip ,then see nothing except a black screen

  • @linstonsequeira

    Yes i know ,i,m just showing how it can still run without the BIOS chip installed after its booted up

  • @dazaro3 i think the bios chip is just for the motherboard to be able to post... if its in windows it doesnt matter much

  • Bios starts it!!!!!!!!

  • bios is only for starting up that's why it works.

    the pc was still running when the bios chip was removed

  • It is posible, i used to program empty flash chips this way.

    And it works because the info from the flash rom is shadowed in the system meory for the speed it takes to read info.

    Normal ram is faster then the flash rom chip.

  • @gwreijman great idea, have few dead boards because of bad flash, now i have a way to do this :D

  • @pisnahuj10 to recover ur bios is easy, jst copy ur bios.rom file into a floppy disk. but u need called amiboot.rom. this only works with ami bios brand. with phoenix u need other method

  • Co ja oglądam?

  • You turned it on so it loaded into the RAM, but as soon as you turn the thing off it will come up with an error telling you to reinstall the BIOS chip

  • in layman's terms

    the bios is a simple operating system blackened shrimp controls the pre and some post control hardware functions untill windows can take over controlling the hardware

  • Hm, this is neither fake nor gay. It actually makes complete sense. The RAM in a computer is much faster than the ROM in which the BIOS is stored, something that lead to the BIOS memory being mirrored (copied) into the RAM. So, once the system has booted the BIOS can (obviously) be removed since the functionality it offers is still available to the system thanks to the mirroring. Rebooting the system without the BIOS thus doesn't work. Nice demonstration :-)

  • @DeathlyHall0w Not fake or gay, I have a similar board and processor, if you reboot it with the chip out it will fail, however the only part it is needed in is booting the os.

  • BIOS - Binary Integrated Operating System

  • @FoxMcCloudMyHero lol fail. Its>>> Basic Input Output System.

  • @FoxMcCloudMyHero a common mistake, here is a quote i found on 'about (dot) com' i also found many other quotes similar.

    "The Basic Input Output System, abbreviated as BIOS, is software stored on a small memory chip on the motherboard.

    BIOS is sometimes incorrectly referred to as the Basic Integrated Operating System."

  • Remember when you could watch a video without having to sit through a commercial?

    Remember when music videos were uploaded by users and not VEVO

    Remember when all the info was to the right of the video?

    Remember you could rate a video 1-5 stars?

    Remember the famous yellow subscribe button?

    WE MISS THE OLD YOUTUBE!

    Post this in every video and lets start a youtube revolution!

    Thumbs up to keep at the top of the page

  • Dennis Ferron's 6502 laptop

  • I've read about using this method - admittedly not going as far as running Windows - as a way of recovering a BIOS chip from a failed firmware upgrade. Obviously you'd need an identical working motherboard and BIOS, but the idea is to take the BIOS out of the working board whilst it's running, put the corrupt chip in its place, then save the settings and exit. I've no idea if it would work, but it might be fun to try!

  • lol said that way 2 soon lol

  • It would be interesting to see what has happened after restarting the computer without the BIOS chip. I am sure it probably wouldnt do more than power up.

  • please restart vithout bios chip and look.

  • I have a PC exactly the same as that. A power surge killed it though.

  • you did it after start up the bios is there to tell the components when to start up

  • it's fast for 500mhz

  • Well, that was kind of disapointing... I thought it would be before the boot.

    Still, nice video though...

  • i want the mobo n cpu ;'[ "my p2 is 1ghz" ;[

  • i want the mobo n cpu ;'[ "my p2 is 1ghz" ;[

  • update the BIOS fahed 

  • haha try that again b 4 u start up and see what happends

  • You don't need the bios after the PC has started

  • @Michaelcooldude you are right..BIOS is for waking up the PC. after all PC is just a stupid machine it need help to wake it up and BIOS is the tool. :)

  • lol man, most plug and play OS's are released from the control of the bios after entering protected mode. The cpu executes the bios boot block code after getting a signal from the pwr_good control wire(this bios is executed in real-mode). Depending on the OS say Win3.x/Win9x would get pissed at you if you removed the bios.(non-pnp OS's get there IRQ assignments from the BIOS)

  • It would be a magic, when u did it before the start up !!!

  • What happen if you don't have windows or any other OS in your computer when you turn it on?

  • hey mate! a computer bios are used at the startup only before the os takes charge of it, no suprise its still working ;P

  • Recently i came across a motherboard that has 8 pin BIOS chip that looks like a transistor. I spent about an hour figuring out where it is :)

  • i thing he has remove the memory of the BIOS, the most of the old boards has a seperated chip wich is the memory of the settings from the BIOS

  • what can the place do on the left of the BIOS 5:06

    I know you can solder chips on it,but what kinds of chips

  • Xp had lots of problems,especially when installing hardware......Vista never gave me problems,just on some software......but only on my laptop?

  • Looking at it from a Tron persepective, the BIOS is SARK... and Windows is the Master Control Program... :D

  • 2:25

    fatality!

  • duh...

  • Correct. After the computer has been booted and is in normal opreation, the BIOS is not longer needed. This is only true for new computers. If the computer was from like 1998 then the computer would have shut down. New computers run off a firmware called EFI after it has been booted from BIOS.

  • is that a abit lx6 mobo? it looks just like mine with pentium 2

  • once it boots it does not use the bios chip. its only used in booting,pretty simple.

  • The BIOS plugs everything into RAM and Windows does the same thing, grabs info from the BIOS and plugs it into RAM. Now heres the cool part. The Linux Kernel doesn't need a BIOS. It reads the hardware info directly like a BIOS would. Gives reason to the CoreBoot (LinuxBIOS) project and such.

  • Well no kidding man, if you boot it up and THEN take out the BIOS it'll still work......Try restarting the computer -_-. It won't.

    You need the BIOS in order to do the most basic input and output functions as the name implies. After the BIOS is finished, it then PASSES it on to the OPERATING SYSTEM. The BIOS is no longer involved.

  • This only works if Shadow RAM is enabled. Shadow RAM copies the BIOS ROM into RAM and then accesses the BIOS through RAM for faster speed. If Shadow RAM is disabled, then any BIOS functions are still done directly through the ROM chip. Some old DOS games won't work unless Shadow RAM is disabled.

  • What the BIOS does is copy itself into RAM which works much quicker.

    So after the boot sequence the BIOS EPROM chip is not longer needed.

  • gotta love the BIOS ROM shadow...

  • what's next?... divide by zero? :-) 

  • awesome power switch!

  • LOL

  • thats not the bios either erm the bios has more pins than that aswell

  • BEAST!!!!!!!!!!!!

  • well.. you also can unplug mouse from PC and still can type in Notepad with keyboard.. Dont ask how it works, this is magic... enjoy

  • WTF cant be done you possibly cant remove the BIOS chip and then booting into windows cant be done its a fake!!!!!! 

  • bios is only used to get to the main op system, after that its job is done.

  • This is very simpel, once the bios is loaded you can swith de bios chip and even save the bios and flash it on antoher chip. This is nothing special.

  • bios is like your starter to your car once its engine is going there no need for starter any more same applies to bios chip

  • This seems like common sense to me, if you know what a BIOS is and does.

  • The board copies the BIOS into RAM during boot, the RAM is much faster than FlashROM so doing so gives it faster access. The board then continues to run using the copy of the BIOS in RAM (until reboot or power cycle)

    In the old days, if you flash your BIOS wrong and mess it up, you boot up a closely matching motherboard and get it into a DOS prompt with you BIOS flashing tools, then you swap the BIOS chip for the one that you messed up and flash it, that's how we used to recover them.

  • The bios chip its no processor its function is to boot up the Operating system and all components after it has done this the bios is not needed.

  • And after reading the posts here I see that this is an old technique.

    I guess I did not reinvent the wheel !!!

    By the time I did that I was not aware of that.

  • 7) Shutdown PC, reinstall BIOS chips in the 2 PCs in their original locations ("ex damaged" BIOS chip in 1st PC, "good" BIOS chip in 2nd PC). Both PCs work without BIOS problems for over a year now.

  • As I explained before I just wanted to share my experience and maybe help other people.

    I should clarify the sequence:

    1) 1st PC with "damaged" BIOS chip.

    2) 2nd good PC working OK.

    3) I started normally the "good" PC, logged into windows (it was XP 64 bit).

    4) While windows running I removed the "good" BIOS chip with a small screwdriver from the PC.

    5) Installed the "damaged" BIOS chip.

    6) Used flash utility inside windows to flash BIOS in the "damaged" BIOS chip.

  • If you have no BIOS you cant run a OS..and aswell you wouldnt have any Interrupts and the hardware would fail at working like the mouse..cause a biso makes the interrupts between the hardware and the programm your using..so i dont get it that you had no lag.. hm

  • Needless to say that this was the last option I had before throwing away the mobo, and also I was scared the s..t out of me, before I rebooted both PCs to see that everything is OK.

    Anyway I could not recommend that procedure to anyone.

  • I should comment that those PCs were 1-2 years old (PCI video card, Core2Duo Pentium, e.t.c., Abit mobos if I recall correct).

  • First time I post a comment in youtube just to share me experience.

    Believe it or not it is true.

    In my office I had several computers, 2 or 3 exactly same.

    One of them crashed on a BIOS update. The PC was unusable.

    I managed to flash the BIOS chip in another PC (with same mobo).

    Powered up the working PC.

    Removed the working BIOS chip and installed the damaged.

    Flashed the BIOS in the damaged PC (inside Windows).

    Everything went OK, the "damaged" BIOS chip returned to the 1st mobo.

  • good display of shadow BIOS at work.

  • how stupid to you have to be to touch the sheared naked ends of a wire together to turn on a computer...with 2 fingers..

  • oh no does it cause bsod

  • A computer only needs the BIOS chip to load up into an OS, other than that, BIOS is complete crap and not needed for anything else but start up.

  • I Could Never To This Myself, But Great Video Man!!!! But Do You Have Any Tips On How To Short Out A Bios Chip On A Toshiba Satelleite A55-S106?!!!!!!!

  • A good display for grade 1 at school.

  • no shit sherlock  you dont need bios after the os is booted

  • DUH!?

  • The BIOS chip just loads the BIOS OS, which then loads the actual OS (in this case windows). After the actual OS has been loaded Into memory, it isn't used. Which is why it's able to work without the chip in.

  • This is real but you can never boot a PC without that chip in.

  • I like the buttons there... got to see keyboard of wires.. hehe

  • I'd be scared half to death of doing something like that to my computer :P

  • its probably fake so the monitor is connected to other pc and motherboard is not operating

  • @sviridovt it is real. this was taken from a camera.

  • not fake this is a way you can reflash a bad bios chip without having to order a new one take out the good one put in a bad one (while in windows of course) run the flash program from windows flash the bad bios chip then replace the chips accordingly.

  • POST refers to Power On Self Test. As the CPU start it check for various things like RAM, ROM, drive controllers etc. As the CPU check each of these it "posts" a numeric code to one port address. As the CPU make its way through the test the number goes from zero upwards. If one functional test fails the number stop therefore diagnosing the problem with the motherboard. Once POST is complete the system boot up the disk operating system or DOS

  • The contents of the BIOS ROM are loaded into RAM on bootup. They do this because any read from the BIOS EPROM requires a long time which would slow down the PC so they dump its contents into quick access memory so it can run at the same speed as processor. The BIOS routines are used while the PC is running. Deep down inside is the Config monitor program. The BIOS routines make the specific motherboard perform the same on all platforms through BIOS calls. Checkout Peter Norton's Inside the PC

  • :) Ingenious power switch haha, and woah! 500 megahertz XD Faster than my computer... Back in 1995 lol. I think the BIOS is only really required during startup, though, which would explain why it still runs - although I expected the mouse not to work :P

  • @MrWindows7Ultimate Noob! Falsch, LOL!

  • I wonder what would it happen if you try to run a program that uses BiOS routines

  • try changing time on your system or doing Suspend to RAM, then you'll be in trouble. With old biosen you could, most of the time, get away with stuff like that. Modern systems are too dependent on bios/efi

  • i didn`t know that?!

    lol

  • i don't mean to be an ass, but you removed the CMOS chip. the CMOS is where the BIOS are stored. Great video, i love the power button!

  • well todays bios are soldered into the board so once burnt gone 4 ever unless u resolder a new one so useless trick ! but cool !

  • i cant understand no shit of whatever u are talking but nice job anyway. how old r u like 80 ?

  • u did that AFTER the start up !!!!!!

  • You could also disconnect the harddrive and still be able to move the mouse around counting you wouldn't click anything that hasn't been cached by the ram :)

  • @rick62008 Sometimes, if you have your hard drive set to sleep after a specific time, or it's coming out of standby and the HDD is still spinning up, it may take a second for the computer itself to respond.

  • @rick62008 u could also remove this video from the internet and no one will care

  • You may have answered this question already, but I can't find it. Why would you do this? Is it proof of concept? Or is it just because you can :P

  • just by remove the cmos battery would do the same thing with out remove the bios ship.

  • I have one question i had a costum made pc Hp Invent. After i added a new hard drive a message started to show up on the loading screen saying "(Error CPU Fan)" the HP loading screen doesnt come on no more if i do this will it take that error message away and bring my hp loading screen back? By the way when i had it made there was never a fan plug to the mother broad i have 4 fan conneted to the main power suply can you help me?

  • you dont need the bios to when you have started up the computer?

  • Well basic computer knowledge tells you that the bios is a mini operation system or program chip that helps the pc boot to the operating system & once it has done its job, its no longer needed because the os is now being ran from the harddrive.

  • Its not a old PCI ,its got a AGP video port ,please look at the spec of the motherboard ,its a AGP not the very old PCI ,the video port is a Advanced Graphics Port, now we have the very fast PCi Express Peripheral Component Interconnect Express video ports.Hope this helps,its all about faster ports ,faster games,faster info from one place to a other on a PC bus..

  • It's a step of "HotFlashing" the BIOS, when i've got a "bad flashed" BIOS, you can put it instead the good one(after you boot to DOS or Windows) and Flash the "bad bios"

  • very old trick with pro-users, but worthless if the pc is OFF and HAS a bad flashed chip, because it wont start up.

    you can also copy running bios on new chip (same type) or flash different bios on an inserted chip... while running. has only to be the same award or ami bios and the same sort of chip and the right, bios related flash program.

    this is all _very_ old.

  • Very nice idea to start your PC with wires =D Seriosly.

  • put more videos its interesting

  • So, that's the BIOS!

  • non func

  • Think of this Dude... the bios chip... is only needed for POST and Boot Strap Load... otherwise its not probably... functioning when ur on the windesktop... :P tnx for it...

  • restart the pc WITHOUT THE BIOS CHIP see if it is possible then. we all know that it loads into ram! DUH!

  • is the motherboard out of a piii 500mhz timeout pc if it is i used to av 1 with 64mb ram , win 98 lol

  • this thing probably cost a fortune back in the day =O

  • Well no because if you connect something then it will not pick it up most of your files will not show up either SO the BIOS IS VERY VERY important

  • it´s imposible... i think he has another computer or anything like this..

  • No its not imposible ,the video is real ,the PC loads the BIOS information into the main memory ,so the BIOS in not needed after it loads the info from BIOS chip to RAM memory ,if i try and start the PC without a BIOS chip then the PC will be dead! ,no BIOS to load into RAM memory.

  • Once the Bios has configured the Hardware and ram it is no longer needed.

    for more information on this topic see google talks Coreboot . there is some neat information there.

  • YOUR PC HAS A RESERVE BIOS CHIP FAIL

  • now restart the pc without bios

  • for all the idiots that does not know why:

    the bios ROM is replicated in the upper block of RAM for fast access the moment your PC powers on, that's why your pc will still run without the bios

  • Actually, modern PC operative systems access the hardware directly without calling the bios functions as it did ms-dos. The bios back in the day was what now we call "device drivers", but today the os uses its own ones. so even the shadow copy is useless. You can check it looking at projects like OpenBios or coreboot, that only provide base initialization for booting an higher os. btw your comment is right :D

  • How do you turn on the PC??????

  • The 2 wires you see on the top right side of the video are the power up wires ,just put them together and PC will power up.

  • usefull for hotflashing another computers flash rom with the same spec. but remember this does not work on all computers. some computers will freeze up or will give you a blue screen and restart and never come back on until the rom is back in the socket. i have a ecs motherboard with a bad rom and it kept on blue screening and the bios menu kept on crashing so i bought a new programmer and rom, flashed the chip and it worked again!

  • what would have happend if u took the bios chip out when it was booting?

  • Usually technicians say "reboot your computer, it might help". In this case - reboot is not recommended :) hehehe

  • lol this vid was uploaded on my birthday

  • i understand, but why?

  • but why????????????????

  • well it will do. it's copyed into memory..it's like starting a car then taking the battery out..??or jump starting a car, you just can stop it or you'll be in trouble

  • Nice video.

  • Anybody can do that. The only problem is if the BIOS Chip is out of the socket when you go to reboot, it wont boot

  • Hi

    How to use Gigabyte's dualbios - how to i tell backup_bios to rewrite main_bios?

  • wow!!!!!!!

  • It's shadowing BIOS, Reads all information in the chip and auto-insert in RAM. If the BIOS hasn't have the Shadowing the PC Crashes when the first drive is loaded.

  • I have 6 PCI slots on my old motherboard but none ISA slots. my motherboard is from 2002 :-)

  • amazing! great video! 5 stars!!!

  • This is nothing new I have done this ages ago

    the only difference was I was recovering a bad flash

    Basically I booted up the computer with a floppy disk with the BIOS and flash utility and remove the working BIOS chip and replaced with another BIOS chip that did not flash correctly

    because the power went out

    well it was flashing the bios.

    Then I initiated the flash command and powerdown after the clashes complete .

    Place the chips back in the computers and both were working again.

  • say what
