BIOS firmware for the Gigabyte GA-B85M-DS3H motherboard, revision 1.1, an Intel B85 micro-ATX board. The 4.98 MB ZIP likely contains an image that can be written to the SPI flash with a programmer when the board no longer boots or a failed update has corrupted it. Gigabyte boards often use dual BIOS chips, so identify which chip you are reprogramming. Confirm the PCB revision matches 1.1, save a dump of the current contents first, and check the file size matches the chip capacity.
