Firmware archive for the Gigabyte GA-H81M-DS2V desktop motherboard, revision 1.0, 5.60 MB in RAR format. The H81 in the model indicates an Intel H81 chipset board. Gigabyte prints the revision on the PCB near the slots, and it matters here because rev 1.0 and rev 2.0 boards can use different images. A dump like this is written to the SPI BIOS chip with a programmer to recover from a failed update. Read and keep the original chip contents first, and confirm the image size matches the chip.
