BIOS dump for the ASUS X540LJ laptop on mainboard revision 2.0, stored in a ZIP of about 3.62 MB and labelled by the contributor as fully working. A dump of this kind is typically written to the SPI flash with an external programmer to revive a board that no longer posts or to fix corrupted firmware. Being a read from another board, it may carry that unit's serial and settings, so reprogram identifiers if required. Read and keep the original contents first, confirm revision 2.0 on the PCB, and check the image matches chip size.
