BIOS file for the ECS B85H3-M3 desktop motherboard, version 1 board, delivered as a 5.50 MB ZIP. No firmware version or chip type is stated, so inspect the extracted image and compare its size with the SPI flash on your board before flashing. This kind of dump is typically written with a CH341A or other SPI programmer to recover a board after a corrupted update or failed boot. Read and keep the original chip contents first, since they may contain the board MAC address and ME data.
