I bought a second hand 3rd gen ryzen but my motherboard needs a bios update to support it. The problem is my pc can't boot without the update and I don't have any way of getting a 2nd gen amd cpu to update the bios. Im thinking downloading the update on a usb stick but Don't know if my motherboard supports it. Can you think of any other ways? I can't take it back to the retailer or ask amd for a boot kit.
