If not, do you have access or know anyone else with same model, or at least similar like the DE3250-S? If you know of some forum/community of users with these I'm sure someone will send you a full BIOS dump. That's not good, hopefully I can find a dump or you can. It is expecting an 8MB file, and I only have a 5MB one. But it gives me an error saying that the size doesn’t match when trying to write. I also used the flashrom software, thinking that might work instead. It is using a 1.8v adapter which is then connected to a SOP8 test cable, which is clamped onto the chip. I was able to read and write to the chip, using the software for the CH341A programmer.

The bios chip that it’s using is a WINBOND W25Q64FWSSIG

I was unaware that the AFUWIN圆4 utility only gave a partial backup. I am not sure whether you’ll be able to find a full dump, as its not really a widely used pc. So, I need your exact full model, so I can build you a new full BIOS from your initial dump I checked, and for this BIOS, I can say now without the info I request, that you cannot simply write the stock BIOS to the board, it's partial BIOS (BIOS region only) and inside a capsule (encapsulated/CAP).

Here is guide on how to setup and use - īefore I can do anything about your BIOS files for sure, I need to know what system this is so I can find a full dump and see if you have complete BIOS or not (I assume missing some stuff, but maybe not critical to function) This may be the issue you are having, or it could be you need to use different CH341A software for the BIOS chip you have, or recheck it's all connected properly etc. Usually, when you backup a BIOS with software like that it's only partial BIOS update, often that is all that is online BIOS update too.
