RAR archive holding a raw BIOS dump labelled only with the flash chip part number, a Winbond W25Q128FV, which is a 128 Mbit (16 MB) SPI NOR device. The name gives no laptop model, brand or board number, so the source machine is unknown. Before writing it with a CH341A or similar programmer, confirm the board really carries this chip and that the image is exactly 16 MB once extracted. Read and save the original chip contents first, since serial numbers, MAC address and ME data are board-specific.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @SCHEMATICWORLD. Enginerys does not host this file.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
