Working BIOS and EC firmware for the Gigabyte B450 AORUS ELITE desktop motherboard, version 1.0, with the ITE IT8733 named as the super I/O controller whose firmware is included. Supplied as a 10.2 MB RAR archive. The B450 chipset places this board on the AMD AM4 platform. Technicians reflash the main SPI BIOS chip, and the IT8733 firmware when needed, with a programmer to revive a board that will not post. Back up the original chips first, and confirm the PCB revision reads 1.0.
