Working BIOS image for the ASUS ROG STRIX B450-I GAMING motherboard, with the RX450IGM token appearing to be the ASUS internal file code for this model, supplied in a 10.4 MB RAR archive. The name marks it as fully working. Use it to recover a board with no post or a corrupt flash by writing the SPI chip with a programmer. Save the existing chip contents first, extract the archive and check that the image size matches the chip, and remember that the MAC and serial may need restoring.</description>
