16MB BIOS image for the M1502YA, with the board revision given as R2.0, stored in a RAR archive. The name gives no brand, though the model code fits ASUS Vivobook naming. Check the revision printed on the mainboard before using it. Write the image to the SPI flash with a programmer such as the CH341A or RT809H after saving a dump of the original chip. Confirm the flash capacity is 16MB, because an image of a different size will not fit.
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.
