e540 bios dump me_cleaner unknown image #286

Hi, I have dual bios chips in my e540, flashrom finally identified the chips but said it could not read 4 bytes, so I used windows 10 as programmer with a ch341a and it read the bios and dumped it, I then took the dumps to linux to use me_cleaner and it says unknown image, how do I proceed?

difficult situation. when you dump specify the chip. If you can't get a verified dump it is risky to proceed. I read some flashrom documentation. Sometimes there are bloc / write protection. This required you to go to the vendor to get EC bios code and doing a lot of work yourself. Sounds tough. Take a look here. Read some documentation from Flashrom it may help. https://gist.github.com/jcs/4bf59314d604538a5098

PS: Linux flashrom can use the ch341a programmer. Windows 10 is risky imho.
