Possibly corrupted BIOS N100 alder lake (AMI)

[PuntaLanza]

Hi everyone,This post may be slightly off-topic, but I couldn’t find the right section for it.

If any moderator feels it belongs elsewhere, please feel free to move it.

I have a generic Alder Lake-N100 mini PC that appears to have a corrupted BIOS, and so far I haven’t been able to find a solution. It has been impossible to locate a clean or original BIOS image for this specific board, and none of the usual tools or donor files I’ve tried have worked.
I’m leaving a link to a blog where another user shows the exact same mini PC model, in case it helps with identification or reference.
If anyone has experience with these devices or knows how to recover the firmware, I would really appreciate any guidance.

Thanks in advance for any help.
