BIOS dump for a board identified as BM5918, revision 1.3A, described as tested and working. The name gives no laptop brand or model, so confirm the BM5918 marking and revision on your PCB before use. Images like this are written to the SPI flash chip with an external programmer such as a CH341A to revive a board that will not boot or has corrupted firmware. Save a full read of the original chip first, and check that the extracted image size matches the chip capacity.
