BIOS firmware for the ASUS X450CC laptop, intended for mainboard revision 2.0, delivered as a 3.45 MB RAR archive. The name gives no detail about flash chip size, version or whether the ME region was cleaned, so inspect the extracted image first. Technicians use such dumps to reflash a corrupted SPI chip with a programmer like the CH341A when the machine powers but shows no display. Read and save the original chip contents before writing, and check that the image size matches the chip capacity.
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.
