BIOS archive for the Gigabyte B450I AORUS PRO WIFI, a mini-ITX AMD AM4 motherboard. The name says nothing about version or modifications, so treat it as a generic board BIOS. On desktop boards such an image can be used to reprogram the SPI flash with an external programmer if the board will not POST after a failed update. Check whether the file is a raw chip dump or a vendor update capsule, since the two are handled differently, and back up the original chip before writing.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
