Small 50.5 KB RAR archive labelled as original firmware for the ASUS S46C Ultrabook board, revision 2.0. At this size it is unlikely to hold a full SPI BIOS image and may contain an EC or keyboard controller firmware, or a compressed partial dump; check the contents before use. Original dumps are valued because they come from a working board. Before programming any chip, read and save its current contents, match the rev 2.0 marking on the PCB, and confirm the file size suits the target chip.
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.
