Can I ask you for a diagram and boardview for a board with this chip?

That is 00840 board; no schematic/boardview available.
We only have 00875 for A1708 model.

However, the same redriver chip is used on A1989 (00850); in case you want make an idea about its function.

I think the problem is in the BIOS! how do you think ? could you help me with a BIOS with a clean region for this board?

Unfortunately, with this the BIOS does not turn on either, this is strange, maybe I’m wrong in thinking that the BIOS is to blame!
