BIOS archive for the ECS G31T-M9 desktop motherboard, version 1.0, 422 KB packed as RAR. G31 boards of this generation commonly carry a small flash chip, and a dump like this is used to revive a board with corrupted firmware by writing the chip with a programmer. The 1.0 may refer to the PCB revision rather than the firmware version, so compare it with the label printed on the board. Verify that the extracted image size matches the chip, and read the chip first to keep a backup.
