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.

[@mahlapropyzm9180]

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.

[@remmyrambrandt9497]

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.

[@martinnash007]

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.

[@DiagolonRider]

man that bios programmer and all those bits are the slickest thing since split bananas!

[@oldbutstillcurious3615]

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.

[@Waaasil]

Thank you for this valuable program

[@corollayanki]

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.

[@spykerhond7008]

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.

[@user474u]

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.

[@caralynx]

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.

[@psycopper1]

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.

[@stanburton6224]

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.

[@hardkore360]

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.

[@coyotex850]

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

[@CoccoUri]

Very intersting video!

[@FireballXL55]

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.

[@supertronicageral3987]

[@denniskubik7360]

You can change the Dumpfile with the Orginalflashfile and use simply the Verifyfunction of the Programmer to compare withe the Chipsaved Data...

[@sstojsin]

Adamant IT you can use good old Total Commander multitool to compare two dumps, it has compare by content option.

[@markharoldespinosa1023]

thank you for this video

[@mhonferari]

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.

[@dannyboyat12]

so if I wanted to rewrite the bios on a lapop where would if find the rreplacement bios

[@WolvenSpectre]

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.

[@reidarcederqvist]

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).

[@rajanne2947]

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.

[@MrDinakdakan]

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.

[@Adamant_IT]

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 👌

[@sipansibabdreddknot5179]

this is what ive seen on the images posted on these ch341a online shop, now my hunch is verified right thnaks!

[@slip0n0fall]

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?

[@Adamant_IT]

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.

[@johnsmith-vz4sk]

Nice to see you haven’t got a clue like everyone else too !

[@aminemarref]

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?

[@Adamant_IT]

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 😅

[@aminemarref]

@@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.

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.

[@almostdarkslide3851]

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.

[@wasfiiwasfi]

also copying / dump of original bios is Very important because most the MB manufacturer these does not provide it, they only provide bios updates as parts of the full bin file, so when a MB/bios is bricked !! you need to search for it on forums (from a user who actually did a dump of him functional bios which is rare). this is why you need to build a well organized archives/backups/dumps of these bios.
