System firmware for the ASUS E402YA notebook, board revision 2.0, packed as a 2.14 MB RAR archive. Apart from model and revision the name carries no version or chip information, so confirm the flash part marking on the mainboard. Such an image is used to bring back a laptop that shows a black screen or no post after a failed update, programmed through an SOIC8 clip. Save a full read of the existing chip, then check that the extracted image size matches the SPI flash before writing.
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.
