BIOS firmware package for the ASUS X456UJ laptop mainboard, revision 2.2, supplied as a 3.76 MB RAR archive. The name gives no further detail on chip type, ME state or EC content, so open the archive and inspect the image before use. Technicians use such a dump to recover a board that will not post after a corrupted update by writing it to the SPI flash with a programmer such as a CH341A. Confirm the revision printed on the PCB reads 2.2, read and save the original chip contents first, and check the image size matches the flash 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.
