ASUS BIOS archive for the X540YA laptop mainboard, revision 3.0, stored as a ZIP of about 2.07 MB. No firmware version or flash chip is named, so open the archive and check file sizes before choosing an image. ASUS boards of this series are recovered by writing the SPI chip with a programmer when the system no longer posts or the firmware is damaged. Make sure the main board label reads X540YA rev 3.0, read and keep the original chip contents, and verify the dump fits the chip capacity.
