BIOS and EC firmware set for the Gigabyte B450 AORUS Elite desktop motherboard, revision 1.0, in a 17.4 MB RAR archive. Having both the main BIOS and embedded controller firmware helps when a board fails to power on or loops after a bad update. Program the SPI chip with a hardware programmer such as a CH341A after reading and saving the original contents. Confirm the PCB shows revision 1.0 and that the image size matches the flash capacity, otherwise the dump will not fit or boot.
