BIOS firmware for the ASUS ROG Strix B350-F Gaming motherboard, version 0401, supplied as a 5.04 MB RAR archive. This AMD B350 board for socket AM4 stores its UEFI on an SPI flash chip, so the file can restore a board that stopped posting after a bad update. Version 0401 is an early release, which matters for CPU support: newer Ryzen processors may need a later BIOS. Back up the current chip before flashing with a programmer, and note that ASUS .CAP files may need the capsule header removed for raw writing.
