- So when I was messing around with the B450 Aorus M, I didn't think it would allow me to flash old BIOSs to test with. It actually did, so I never really needed this widget - but anyway here's a video showing how I used a USB EEPROM programmer to flash two blank BIOS chips with a backup of the factory chip. Now I have the means to fully recover a mobo that's BIOS bricked and does not have flashback. KIND OF INTERESTING.
I think the dump was 16 MB not 16 KB as stated in the video. I.e. 16,384 KB is 16 MB or thereabouts.
I recommend using a hashing algorithm to create checksums and comparing them.
I use md5sum on linux. I will read the bios and make a backup bin file. Then do it again. Then I take Md5 checksum on the two backup files and make sure their hashes are the same. This test just makes sure my flasher is reading the bios correctly. After I write the new bin file to bios, I will read bios and create 3rd backup file, then do md5sum on both the new bin file that I wrote on the chip and the 3rd backup file. This tests if the flasher wrote to the bios correctly. md5sum is a linux bash terminal tool that uses md5 checksum to verify data using md5 hashing. There has to be a Windows program that does md5 or sha checksums, but I don't know. My computer is linux. There could be a powershell equivalent.
This might work, but don't have Windows to test!
Get-FileHash -Algorithm MD5
Run this on each bin file you want to compare and make sure their hashes are the same. If just one bit is different, than the hash will be completely different.
Very interesting, thanks for that. A good idea to get all of the adapter gizmos too.
Note that there will be a limit to the number of times you can desolder and resolder the chips before the pads give up the ghost, at which point you are quite hosed.
eeeprom manufacturers test every new chip with some random data and then verify it to confirm the chip is good to go. Every brand new eeprom will have some data in it. You have to make it blank before using it. Thats like the "ok tested" digital tag for the new chip.
Wrong, generally new chips are shipped blank so you don't need to erase before writing to them. If you see data on your flash chip, chances are it's been recycled.
Adamant IT: An excellent app for comparing files is Beyond Compare (BC), I've used BC version 4 to compare hex data in files generated by a different brand of programmer. The app is versatile as it also compares handles text files etc. I think it is a try before you buy app, certainly one of my best buys - I marvel at its power.
Just for future reference, you shoul pull the coin cell for two reasons, first off it is still poweringvthe RTC/BIOS circuitry, second if you overheat it from the hot air it could leak nasty stuff on your board.
Thank you for the tutorial ! The flashing process worked flawlessly. The one thing that i had to do was to edit the CAP file (ASUS) and take out the CMOS battery for a minute. I did not had to use the clamp, i just removed the chip directly.
Very good film , you are the building blocks the entire internet should consist of.
That specific program that you need was a new BIOS program for that type of motherboard. Just download it in the internet and write it into the chip. But before you start the process you need to erase the corrupt BIOS or the old BIOS written on that chip. There you can proceed reprogram the BIOS chip.
so if I wanted to rewrite the bios on a lapop where would if find the rreplacement bios
man that bios programmer and all those bits are the slickest thing since split bananas!
I love your videos and especially your intro music mann. It is sooo goood.
Hi, Notepad++ could also be used to compare 2 files side-by-side. You have to install the compare plugin.
But you can't use the HEX Editor and Compare plugin side by side
Source: I have tried it
HxD is the program you can use for opening bin/rom files. It has a compare feature too....if you haven't come across it yet. Cheers.
To compare the bios you need to put the chip on the programmer then select a bios as if to flash it an then press verify, and it will compare both an tell you if they are the same.
If this thing would work on a real operating system, there would be diff command. :)
What happens if I leave the clamp on the bios chip after programming and switch on the machine? (not connected to the programmer but just clamped on because it is really hard to get the clamp in place properly) in case I have to reprogram again?
The programmer has a verify function .
Load your file & verify it against the chip !
Simple …
RTFM it may help a bit or you can nibble on the chinglish .
the author is not interested in answering my question.... can you plz help.
1- I have downloaded latest Bios from Gigabyte and its not .Bin file. How would i convert it to .Bin????
2- I use UEFI Tool and load the Bios file and save it as .Bin
3- Load it to EZp tool, Erase data from chip, Write that converted .Bin bios data to chip.
4- When it goes to Verify it gives a error.(Flash Check error address:20000h
One thing is that when i plug Bios Chip into Ezp2019 kit, it always detect it as "Chip Detected - 24EEPROM" ... meanwhile i am using Gigabyte AorusM b450... same the author used.....
Your overhead camera is bloody awesome with it's super macro.
when it comes to bios problems the most common thing i see is people locking themselves out of it by setting a password and then entering in incorrectly a bunch of times, in most cases reseting it or trying to enter the boot menu is impossible so i think this tool could come in handy for that
An easy thing is load the downloaded bios file to the buffer then click verify. Note: If the bios file on the chip has been modified with just sa single parameter like password, they will be different and therefore there will be a verification error.
ok thing important solder a thin cable between the pin 4 and the ground... the clip is not evident to put on place... did my z170-a-pro with ezp2019+
I have an MSI A68HM-E33 board ,which stops at Post boot screen and my keyboard and mouse is NOT responding in order to go to bios. Will re-flashing the bios gets me into the bios in order to change my boot order ???? Is my """ stuck in post boot""" a corrupted bios issue ????????
The built in DOS command FC
e.g. FC {file1} {file2}
For more information about the command FC /?
You can send the out to another file with something like this:
FC {f1} {f2} > fc-output.txt
hi again can we have a direct on a board reprogramming ? i need to flah a brick card and id like to know if possible before to buy the ez2019
Please what is the difference between
ezp2019 vs ch341a and which one is better
This is super cool, man. Watching you work, I feel like I'm getting acquainted with forbidden knowledge. Again, very cool.
The 25u12873f chip is a 1.8v chip? Do you need a 1.8v adapter to not damage the chip?
Same question. My x470u4 died on me after a flash.
Same chip as he has in his video
i think some male-female jumper cables that commonly used for breadboarding could be used for that JTAG-to-EZP2019 connection. :)
I suggest you to at least dump the bios twice so you can compare the two dumps, they are small anyway. As somebody already mentioned, use HXD to compare two files, if I remember correctly it also let you chose hexadecimal and other formats.
There are various file diff and merge tools with a GUI interface which, whilst their primary purpose is working with text files, will also allow you to compare and edit binary files (presented in a hexadecimal format).
Examples are WinMerge (open source), Araxis Merge (30 day trial) and Guiffy (21 day trial, cross platform support).
Even Total Commander has Compare by content functionality.
HxD has that feature too
This got rid of "mac address invalid both cmos and flash" on my ASRock board
I have seen 2 winbond chip on that motherboard, how to recognize wich is the right chip to re-flash ? Regards Alessandro.
this is even better than the non bricked msi boards coupled with their in house flashing methods that are so deliberately laid with processor bug landmines. For the price the bastards can include a kit like this with motherboards and scrap all the plastic cableties and extra sata cables. Thanks for this informative piece of work.
Like I said last video I ordered that mb and I was worried but when I received it, it does have the newest bios on it and it says 3000 ready so they must have found out they messed up and now sending them out with 3000 ready
Hello,
I want to reprogram the eeprom 24s08 of my lenevo T500 pc, because the bios is corrupted. I can't find a copy of the original Bios ..
.bin, I need your help to get an identical copy to the original.
Thanks in advance.
hello mr. can you help me find the acer aspire one d255 bios, PAV70 LA-6421P, I've been looking but can't find it. please
I have troubles to connect my EZP 2023, I have Windows 10, so how can I connect my device tonget ready?
do the flasher read 1.8v flashes out of the box ? so why they sent an 1.8 adapter in the package also ?
Cool. I like these videos that solve a hard technical problem with a laid-back attitude that makes look anything is solvable. My question: why did you unsolder the chip as opposed to just grabbing it with the "grabby dude" you showed at the beginning?
Honestly - I forgot that it was in the box and forged ahead with desoldering! The talking-head sections of this video (intro and latter part) where all recorded well after I did the actual repair work 😅
@@Adamant_IT Cheers :-) I wanted to make sure that the crocodile clip thingy works and could actually grab the chip.
There's no reason why I shouldn't, but I'd expect it to be rather fiddly. Don't forget to take the RTC battery out.
@@Adamant_IT Thanks :-)
HI ADAMANT
I ORDERED THIS AND SHIPPED TO ME IN 20 DAYS
but now i have a problem with 24c64 ic chip
its not recognized
does that tell me that the chip is burned or which adapter i have to use
why did you desolder the chip? ive got to flash an asus prime b450 plus board myself bc some mother fr traded me a board and didn say the bios had a bad flash and it wont display but does power on no beeps..i have a flasher but last time i did a gpu i didnt desolder the chip i simply used the clamp?? why diid you take the chips off? please explain?
NEVER MIND BUD got to the end seen its NOT needed to flash it thanks. will edit if im able to flash this board and save it gonna run a 1080 strix with a 2400g for my wife. i have a 2070 super ftw3 ultra+ with a 1600af@4.1ghz @1.33volts.
I tried to repair the bios(L-I946GZ) by soldering (soldering iron) and it failed(For I thought that the one used in the video was a soldering iron.).
I'm a beginner, so it seems that I have to use hot air (heat gun).
What kind of hot air (heat gun) should I get?
If you could teach me, it'll helps a lot.
Could you link me to the adapter that would be needed for the header on Asus boards, because my board also has one. The bios on my board recently got bricked after a bios update, though it's still under warranty so I'm gonna RMA it. But It'd be cool to have this as a backup if something were to happen in the future.
To anyone that is interested. I found a programmer that can work with the SPI header on my ASUS motherboard (and other boards I assume that have similar headers). Its the FlashCatUSB Classic. When you order if you can get it a 8 pin 2mm pitch jumper cable, which you need for the header on the board. I really wish I knew about it before I RMA'd my board.
hello..l have ezp2019+..when i click (test) this message appear(chip detected:93EEPRoM please manually select the corrisponding type burn)..but in the socket i put an SPI flash 25VQ32..there Is no 93eeprom!! what am i wrong??!
The auto detect isn't great on the EZP, I would manually select the chip. If you can't find it in the software, it's not supported by that software version. I haven't used my EZP in a while (currently using an RT809f or a CH341a), so I'm not sure how much updating the software has had.
lets try on the top slot...IT WORK NOW!.. thank you .I was with some problem that the chip was not detected .and you shou me the way :) greeting from Portugal
EZP2019 có thể hoạt động với chíp bios 1.8 V sao? chúng không cần adapter 3.3 to 1.8v ???
Hello, do you know can we read the car srs module with this ezp? And fix it
Hi , And thank's for your video.
Do you know what are the requisites for bios chips?
I do not want to buy anything else since i allready made an universal programmer card that may allready support these chips.
Sorry if my english is wrong.
Hello.
HXD is fine for comparing hex files, also free :)
I second HxD, it's my go-to
Great video I've been thinking about flashing the Bios on a old Dell Alienware laptop I was wondering where you bought your programmer ? I've seen a couple on eBay but not a complete kit like yours .
Hello, first of all congratulations on the video.
I have the same motherboard, and I have the problem that gives an image, the led dram turns on and then vga, and so on in a loop, it stops and turns on.
If I unplug the gpu, it does the same.
At what temperature do you desolder the eeprom?
Thank you.
imagine i've watched the whole vid without skipping, thumps up sir. ;)
My idea: dual bios modchip on mobo that don't have dual bios, with tiny switch you can flip
we have the same bios chip, the MX25U128.. type.. but based on the datasheet its a 1.8V types, you just plugged it in directly to the programmer but get detected and reprogrammed.. mine was not detected and i had to use the 1.8V adapter.. but still won't go.. btw im using the CH341A programmer and the software is Asprogrammer 1.4 .. which both can't detect the 25U128. i had to manually select chip, after reprogramming for several minutes, read the chip, and its empty.. or do I need to buy the EZP2019 ? or try the software bundled to that ?
i have the same chip MX25U12873FM2I (asrock b450) any information on how to flash the right way
I watched and and like your video regarding flashing the BIOS chip.
I has the Dell Precision T5500. The BIOS doesn't support PCIE NVMee SSD Boot.
The Dell OptiPlex 7010 has the same old features that doesn't support the PCIE NVMe boot also, but they modified the BIOS drivers to make it bookable.
Can you modified the Dell Precision T5500 BIOS to boot off the PCIE NVMe SSD? If you can. Would you please show us how?
I would convert the bin files to PDF, and then use PDF compare in Adobe Acrobat Pro, it would easily do what you were after.
We do this at work all the time when comparing older revs of documents against the latest revisions.
hello, does this EZP-2019 SPI programmer work with 5 volt automotive eproms like 93 and 95?
Hey great video! thinking to buy this...!! Regarding the bios update in the Windows environment is it safe to update from the oldest version to the newest i understand not right? Which is the right step to flash all the bios versions gradually? Thanks.
I have an problem with 28lc128i chip ,when I'm writing the chip it's adding some extra data that is not supposed to do ,why is that ? I don't know if the problem is in the software or the hardware
in windows command prompt run "fc /b file1.bin file2.bin" and the output will give the file differences. fc is the file compare utility in windows! you can redirect the output to a text file if you want to study it later with " > difference.txt " too.
Adamant IT you can use good old Total Commander multitool to compare two dumps, it has compare by content option.
Hi i wanna ask you about the programming of eprom of tv do i put the eprom option or spi flash in software option and i think this programmer cannot erase because i tried it but the bank option giving me the fash is not empty may be there is a solution for it can you help me plz thx
EZP2019 programmer does supported winbond flash 25Q32FVSIG or not as I try to write or erase but failed?
Operação de fonte de alimentação única- 1,65 a 2,0 volts para leitura, apagamento e operação de programação-erações
I have been looking at doing this for a X370 that appears to have a corrupted BIOS that won't post with no flashback. Now I am considering getting some extra chips and make this my excuse to finally get a hot air station as well. Thanks for the suggestion.
is this good for motherboards which dont give dispay on monitor but everything works from ventilators,start,lights....?
I need to flash mx25L12845e chip how do connect SOP 16-pin Clip to the programmer? What adapter I need?
I have a SOP16 socket adaptor into 8-pin, looks like this: www.ebay.co.uk/itm/185513234157
you can convert the hex back to assembly, at least is more readable!
Nice video. Im buying one to flash a SOP16 chip on a ToughSwtich TS=5-POE. The Winbond chip is faulty but the bootloader part of the file in intact; the full firmware doesn't boot. I'll copy it then hopefully TFTP'ing to the new chip and flashing again should fix the problem.
Which cable do I need to connect the j-tag to the flasher? idc 2.5 mm 10 pin?
Love your videos. I noticed a few comments on whether the clip works. I tried it and it does but with a lot of fidgeting and eventually you get lucky. You mentioned that it needs some mods before it can work properly, can you tell us a little more please. Also I was successful at erasing and writing the bios but every time I verify I get an error 10h. Can you help please. It would be great if you could do another video on the programmer
I did some more research and I was able to do the mods needed to make this thing work with the clip, see link below for info, it explains step by step, it's very simple and actually works, I was able to fix a non working board.
If you aren't too sure about soldering you must watch Adamant's "Soldering crash course with amateur equipment" it helped me!.
Thank you Adamant

Do you know by any chance where the bios chip is on a toshib Tecra r850-119 laptop motherboard?
i found the function of the lower slot: The programmer can copy one chip to another chip.
When the programmer detects two chips on the socket, it will automatically start copying operation.
1. When off-line copying, the programmer can link to 5V power as well as link to PC.
2. The programmer can copy data to a 24 eeprom from another 24 eeprom.
3. The programmer can copy data to a 25 flash from another 25 flash.
4. The capacity of destination chip must be equal to source chip.
That's very interesting if it can do that without a computer link... I'll have to test it with some spare chips I've got 👌
this is what ive seen on the images posted on these ch341a online shop, now my hunch is verified right thnaks!
I did the exact same but after soldering the bios chip back there's no signal just black screen :( what could it be??
Very good video. I have a motheboard h61h2-cm with bios problem (No Video) this can work with my motherboard?
Where did you buy your EZP2019 kit from, Thanks
Great video mate, thanks for taking the time. Maybe an obvious question, but in your research is it typical for the bin file provided from motherboard manufactures to reflect the entire contents of the flash EEPROM?
Yes, although 'empty space' data represented as say, a zero, still counts as data. So the BIOS file will still be 16MB on these AMD boards even if sections of the BIOS are unused.
@@Adamant_IT is compatível with Plcc32 ?
You can change the Dumpfile with the Orginalflashfile and use simply the Verifyfunction of the Programmer to compare withe the Chipsaved Data...
Hi man hope you doing good
So I'm having a problem in my asrock b450 steel legend it won't post tried multiple CPU's and it still won't display someone told me use the eeprom method do you think this gonna work replay fast please!
Worth a try 👌
So you write a new bios program from the Website? or use the old one from back up? sorry i didn't get the clear explanation about that (My Mother Language Isn't English) Thanks
i have x570 tuf asus and i need to downgrade bios
will ezp 2019 help me?
You'll need to be able to remove the BIOS chip from the mobo, and most likely it'll need the 1.8v adaptor that I showed in this video too. I've still not had a successful result with the clamp cable, trying to flash the chip in-circuit doesn't seem to work.
hey bud do you have link to the software for the flasher? I have ezp_xpro v2 but cant find software anywhere
THIS WILL WORK TO ANY LAPTOP AND ANY DESKTOP SYSTEMBOARD?
In the States here, We have a lot of laptops with the ENE 9000 startup chips with the bios built into them. Can you do a video on this :) . I am to understand (?) that on those chips you have to backup the bios and another region for the actual firmware that runs the startup chip.
thank you did very well, sorry sir my question your write one bin to all two bios chip?
small correction there, before removing the bios chip ALWAYS remove the bios battery (CR2032) as its powering the chip and you might run into bios corruptions, and furthermore..it can blow up in your face when using a heat gun around it...
yeah try using the clip one first... it's easy and more cheaper
i got a question, i used the same software and programing tool, now after i flashed the bios, the loptop wont turn on.. before i flashed bios, its turning on and off, but after flashed it wont even light up.. can you help me what to do? or what would be the cause?
Double check that your pin is soldered on correctly. I do believe pin 8 should have the 3V3 voltage on it to run the chip. Other idea is possibly wrong bios.
you have to use uefi tool or an equivalent one to read this files....with this tool you can change something in the bios, like the uefi boot support for nvme drives on older boards, that havent a nvme slot
So the supposed blank microchip actually had some software on it?, untill u erased it?
Ok I just bought this programer I plan on flashing my 5700xt that I bricked any suggestions
Can I use this to flash the bios chip of the Asus b85m-g motherboard? Thanks
Probably yes. Consider checking out the CH341A for a budget programmer as well, it's got good support and it's super cheap.
Hi another good informative video.
The BIOS chip is not powered by the CMOS battery although it is always better to be safe than sorry.
I have on some laptops performed a BIOS crisis recovery where you hold down a key combination during power up, and it invokes a boot loader that is in mask ROM, this will import a new BIOS image from a USB stick.
I bought this programmer but I don’t know if they are compatible with the 1.8v chips without adapter, if someone’s know pls help!
You will need a 1.8v adaptor, yes. Should cost less than $5 / £5
For drivers you can use Zadig and install libusb one without disabling signing enforcement.
ok
are there any programmers that can work with a Microsoft surface laptop 2?
Hey guys I’m new to this but just wanted to know, since he was able to reflash bios. Does that technically mean someone can program their bios cfw and flash it?
Very late reply but Winmerge or Windif will probably do what you want in terms of comparing files.
I have tried this a couple times but when i soldered the chip back on it doesn't work thankfully they where cheap boards
hi man!
so i got someone did this bios flashing for me but it didn't post i wanna know why you took the other chip from the motherboard i'm not talking about the bios the other chip that behind it and why ? do i have to programme it too ? pls answer ty
This mobo is a dual-BIOS board, so it has two BIOS chips.
@@Adamant_IT ok ty for replying i wanna know which programmer is good for my chip:mx25u12873f also is this chip 3.3 or 1.8v i wanna make sure before i flash and what do you recommend to do if this is your chip ? pls answer ty
Also I'm scared to update my Gigabyte A320m-h motherboard after seeing the crap you went through.
That was more due to his lack of reading what was and was not supported. Using a Bulldozer CPU for a Ryzen board was probably not the best of ideas.
What is the difference between the backup and the main chip? is it the same BIN file?
Ah those were the days with the old American megatrends bios chips mounted in sockets that you could prise off and substitute or re program. I wonder if you could replace the ones onboard with sockets and then remount them? Course surface mounts wouldn't have the pin length but I suppose you could replace the surface mounts chips with ones that do plug into a socket?
Theoretically you could convert a mobo to a socket if you were swapping chips all the time... I've noticed that a lot of new boards (X470 and up) have pin connectors near the mobo chip you can use to interface. Not acquired the cables for them yet though.
@@Adamant_IT I'll stay aware of that- it was a real treat back in the 90s with the Maplin catalogues that gave you pages and pages of new chips et with pin layouts Vccs and more data to chew over. Ah a dying age and my daughters both enjoy my vast collection from valve radios (working) to early transistor pocket to reel to reel to cassette to mini disc to cd to ! All working and experienced by them to realize modern tech often doesn't have the build quality or the sound warmth particularly from my valve amp system. 14 hz too 24Khz you can hear the pin drop on that ☺
One thing I have found is the way manufacturers are chucking out ie motherboards with issues more and more regularly. That raven ridge APU caught me out recently re a no post no vid out simply cos the bios even on a board supposedly Ryzen 3 3000 ready wouldn't run a 3 3200G though replaced with a Ryzen 5 3600 it did post et no probs. Years ago you did factory quality control but these days? and as for after sales service ?!
