BIOS firmware for the ASUS X450CC laptop, mainboard revision 2.0, compressed as a 3.53 MB ZIP archive. Revision matters on ASUS boards, since images for other revisions of the same model may not boot. The dump is intended for recovery by writing it to the SPI flash chip with a programmer such as a CH341A or RT809. Before flashing, read and keep the existing chip contents, check the REV marking printed on the PCB, and make sure the extracted image size matches the capacity of the installed flash chip.
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.
