BIOS for the ASUS E402YA laptop, mainboard revision 2.0, compressed as a 2.06 MB 7z archive. Besides model and revision the name gives no version or chip details, so check the flash chip marking on the board to confirm capacity. Technicians use such an image to revive a notebook stuck on a black screen or failing after a bad update, reflashing it with a programmer and SOIC8 clip. Read and store the original chip first, and make sure the 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 @biosfiles. Enginerys does not host this file.
