Hi! I would need that bios. Where can I get it?
Without know the Make & Model of your RX480 I just googled your title and found that TechPowerUp has a UNVERIFIED BIOS for that GPU Card: https://www.techpowerup.com/vgabios/228064/228064
Run GPU-Z to find out the exact Make & Model of your RX480 to see if TechPowerUp has a VERIFIED version to download and upload the image.
