BIOS package of roughly 6.65 MB for a board identified only as 5440, marked as tested, edited and fully working. The name gives no brand, so the model number alone should be checked against your machine before use. Edited dumps like this are generally written to the SPI flash chip with a programmer such as a CH341A to revive a board with corrupted firmware or a locked configuration. Read and store the original chip contents first, and confirm the image size inside the archive matches the flash chip capacity.
