BIOS firmware packed in a 3.58 MB RAR archive for a laptop motherboard numbered 10124-3. That number follows the Wistron board-numbering pattern, so the board was built by Wistron for whichever brand sold the notebook, and the name gives no model or brand. Technicians use such dumps to reflash a corrupted SPI chip with an external programmer such as a CH341A. Read and save the original chip contents first, confirm the board number on the PCB, and make sure the image size equals the flash chip capacity.
