BIOS package for the ASUS X402CA laptop, packed as a 3.51 MB zip archive. The name carries F1_8_1_209, which looks like a revision or build tag, though the exact meaning is not stated. Technicians use such a dump to recover a board stuck on a black screen or failed update by writing the image to the SPI flash with a programmer such as a CH341A. Unpack it, compare the image size with the capacity of the chip on the board, and save a backup of the original contents before erasing or writing anything.
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.
