BIOS archive for the ECS B350AM4-M desktop motherboard, an AMD B350 chipset board for the AM4 socket, supplied as a 6.37 MB RAR. Images like this are used to recover a board that fails to POST after a bad update or to restore corrupted firmware by writing the SPI chip with a programmer. AM4 boards commonly use 16 MB flash, so compare the extracted image size with the chip capacity before writing. Dump and keep the original chip contents first, since they hold board-specific data such as the MAC address.
