Hello, I bought a donor board for the Toshiba MG09ACA18TE (part number G0082A) because broken sata connector. Now I have transfer bios, bevause the drive isn't recognized by the bios of my PC. In this video : https://www.youtube.com/watch?v=QeBnEQvhl84 I see it's is the chip Q100 (0:42), but it's is a TPCA8131, what is a MOSFET: https://www.alldatasheet.com/datasheet- ... A8131.html Does anyone have an idea?

With kind regards,
Rene

can you take a good photo of your board, and also have you identified other chips that are actually flash memory, maybe IC5?

LOL! Yes, that is very stupid. Just another reason not to buy from them.

Thx! I made some pictures, but it was very difficult to make sharp pictures. I upload the here, but I think it's ic4 (it seems to be it's a W25Q32JWBYIM). I will try to do a bios transfer bij onboard flashing with a programmer.

I made some better picures.

I would have thought this would have been OP's first step. how does one know how to connect a programmer, take dumps, manipulate dumps and reflash if identifying the chip was the hard part?

I expect that IC4 would be the "ROM" while IC5 and IC6 (unpopulated) could be nonvolatile cache for power loss data protection.

Winbond typically are writable. The GD25LH32D is likely fixed ROM device. Both look like a standard clip on chip reader can possibly read them both.

The GD25LH32D probably has disk tables when the assembly was made originally. Probably has bad block tables too.
