ASUS VivoBook 14 X442UF BIOS firmware in a RAR archive of about 5.56 MB. The name gives the model but no board revision, so the matching revision must be confirmed on the mainboard before use. Images like this are written to the SPI flash with a programmer such as a CH341A to revive a laptop that will not post or that bricked during an update. Read and save the original chip contents first, compare the file size against the flash capacity, and preserve the serial and UUID data when possible.
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.
