Can the same USB Pendrive contain MULTIPLE BIOS files?

So to update my BIOS firmware, I go to the manufacturer's website, download the next (following the current version) BIOS firmware version (zip) file, copy-paste it onto this USB Pendrive and then extract it in there using 7-ZIP. I do keep the original ZIP file in there as well.

This has worked so far.

However I want to know if I could have multiple (older and newer) BIOS files (the original ZIP file and its extracted files including the EFI folder - so every single part of the zip file) on the exact same USB Pendrive and still successfully either update or revert the BIOS firmware version(s)?

Sure. You can keep multiple BIOS versions on a drive. What I would typically do is simply rename the BIOS updates that I don't intend to use by adding something like a ".old" to the BIOS file names. This way I won't accidentally select the wrong file.

Also, depending upon the system that you are updating, some systems insist that the BIOS have a very specific name no matter what the version is. Again, simply rename the BIOS files not intended to be currently used.

I think you misunderstood me. I meant if I could have multiple BIOS files on the exact same USB pendrive in that the original ZIP file would be kept BUT also extracted, so I think realistically I would have multiple .nsh, .efi, .(insert version number like F5d, F5e etc)files and EFI folders on the same drive.

Would it still work or would the BIOS update go corrupted thus my MOBO would wrecked?

I am saying I wouldn't create specific folders dedicated to one specific BIOS firmware version like F5d etc

My apologies, clearly you are correct and I am misunderstanding. I am used to a BIOS update file being just that - a single file.

It sounds to me like you are describing a USB disk that is bootable and as a result contains more than just the BIOS update file itself.

Honestly, that would be a question best answered by the device manufacturer. I can think of ways to do this, but there is no way I'm going to share those thoughts because you will then be mad at me it it doesn't work as expected and bricks your system .

BIOS updates are NOT something that I would take risks with. Typically, BIOS updates are infrequent events. At least for me personally, I wouldn't spend much effort trying to rig something best not experimented with. My personal opinion is that you should follow the manufacturer's procedure PRECISELY.

Apologies for not being more help with your question.

Just a sec I'll share a screenshot in a minute so you understand

So basically look here https://imgur.com/a/SaxEix6

I am asking if I could have 2, 3, 4 or even more BIOS firmware versions exactly like this on the exact same PenDrive without putting them in their respective subfolders named after the BIOS firmware version like F5d, F5e etc etc

Sorry, I have no further thoughts on this. Maybe someone else will have something.

the answer is yes. If you are doing it from bios ezflash, just navigate to the bios file you want it to use.

this one





the other stuff is not needed

Thank you internet stranger - this is the piece of information I was looking for. I am upgrading from an R5 2600 to an R7 5800X using a B450 mobo so I'll need to update the BIOS. I was hoping I could keep my current BIOS version as well as the updated BIOS on the same fatty stick.
