Working BIOS dump for the ASUS X542UQ laptop at board revision 2.1, packed as a 5.35 MB RAR archive. The image is meant for writing to the SPI flash chip with a hardware programmer when the laptop is dead, has no display or loops on boot after firmware corruption. Before flashing, read and save the original chip, which carries serial and other unit data, and check that the extracted file size matches the chip capacity. The board revision printed on the PCB should be 2.1.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
