ASUS X540SC BIOS dump for mainboard revision 2.0, delivered as a RAR archive of 7.58 MB. The name identifies the flash part as a Winbond W25Q64F, a 64 Mbit (8 MB) SPI NOR chip, so the extracted image should be exactly 8 MB. Technicians write such a file with a CH341A or similar programmer, typically using a test clip or after desoldering the chip, to repair boards that power on without picture. Check that the PCB states REV 2.0, read and keep the original contents first, and verify the write afterwards.
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.
