Gigabyte GA-H81M-D2W motherboard BIOS, revision 1.0, compressed in 7z format. The file name specifies an 8MB image, which corresponds to a 64 Mbit SPI flash chip on the board. Technicians use such dumps to revive boards that fail to post because of corrupted firmware, writing the chip with a programmer like a CH341A. Extract it with 7-Zip. Read and save the original contents before flashing, confirm the revision silkscreened on the PCB, and verify the chip capacity matches the 8MB image.
