BIOS image for the ASUS ROG STRIX B350-F GAMING motherboard, firmware version 5603, in a 9.70 MB RAR. The B350 is an AMD AM4 chipset, and this board keeps its UEFI firmware on an SPI flash that can be rewritten with an external programmer when an update fails or the board stops posting. Save the original chip contents first, since they may include the MAC address and serial data. Make sure the file size matches the flash part before writing.
