BIOS archive for a board identified as TM3147 with part number 920-003094-02, revision A, in a 9 MB RAR. The name gives no laptop brand or model, so identify the target device by matching these numbers printed on the PCB. A technician uses such a dump to reflash a corrupted SPI BIOS chip with a hardware programmer. Always read and save the original chip before writing, confirm the revision letter matches, and check that the image size corresponds to the flash chip capacity.
