BIOS firmware for the ASUS Zenbook UX31A2 mainboard, revision 4.1, distributed as a 3.58 MB RAR file. The stated revision lets a technician match the dump to the right PCB, which matters because different revisions of one model can use different firmware layouts. It is intended for direct reprogramming of the SPI flash with a hardware programmer when the system fails to start. Back up the original chip before writing, check the revision marking on the board, and ensure the extracted image size corresponds to the chip capacity.
