Working BIOS image for the ASUS K401UQK laptop mainboard, revision 2.0, marked as tested and fully functional, with a note that the fast boot setting is enabled in this dump. Packed as a 12.1 MB RAR archive, it is meant for reflashing the SPI BIOS chip with an external programmer such as a CH341A when the original firmware is corrupted. Confirm the board revision printed on the PCB, read and save the existing chip contents first, and make sure the extracted image size matches the flash chip capacity before writing.
