Windows executable of about 5.21 MB named 114A_Cap64S; the name does not clearly identify the vendor or model. Cap in such names often refers to a BIOS capsule file, and 64S may indicate a 64-bit tool, but this cannot be confirmed from the name alone. Utilities of this kind are usually BIOS update or flashing packages run under Windows. Check its contents in an archive tool before running it, confirm it targets your exact model and make a backup of the current firmware.
