BIOS firmware package for the ASUS D540Y and X540YA notebooks, revision 3.0 as stated in the name, compressed into a 2.04 MB RAR. The name does not say whether it is a full SPI dump or a vendor update file, so inspect the extracted image size first. For programmer work, read and save the original chip contents before writing anything, and make sure the image matches the flash capacity. Also confirm the motherboard revision printed on the PCB matches 3.0, as firmware from another revision may not boot.
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.
