BIOS archive for the ASUS K43L laptop, board revision 2.0, with the HM65 chipset and marked as working by its OKOK suffix. At 1.45 MB compressed it likely holds a small SPI image of the kind common on Sandy Bridge-era machines. Write it with a programmer such as a CH341A after reading and saving the existing chip. Match the board revision and chipset, and check that the image size matches the flash chip capacity before writing.
