BIOS for the ASUS X420UA laptop, with 2.0 in the name, most likely the board revision. It comes as a 5.78 MB RAR archive with no chip or version details given. A dump like this is used to recover a notebook after a failed BIOS update or corrupted flash, by writing it to the SPI chip with a programmer. Check the revision silkscreened on the mainboard, back up the original chip contents first, and verify the file size against the flash capacity before programming.
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.
