Raw 8 MB BIOS dump for the ASUS X541NA laptop, with 2.1 in the name most likely referring to the mainboard revision or firmware build. The file size corresponds to a 64 Mbit SPI flash chip, the usual capacity for this class of notebook. Repair shops write such images with a programmer such as a CH341A or RT809H to revive a board that powers on with no display or loops after a failed update. Back up the original chip first, since it holds the serial number and other unit data, and check the revision on the PCB 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 @ITHINKHS. Enginerys does not host this file.
