🙁 Thank you.American Megatrends R1170Y8 is the BIOS maker and BIOS version, not the motherboard model.
Official BIOS updates for laptops are provided by the laptop manufacturer if any such updates exist.
Unfortunately it appears that Sony have removed all downloads for your model, except for printed matter:
