Firmware archive for the ASUS X542UQ, with the name also mentioning the X542UF, so the images may suit both variants.

Technicians use such files to reprogram the SPI chip on a board that will not power or post. Confirm the exact model and revision on the board, save the original chip contents, and check the image size against the chip before writing.
