BIOS image for the Gigabyte GA-EP31-DS3L desktop motherboard, revision 2.1, stored in a RAR archive. Gigabyte often ships several hardware revisions of the same model, and BIOS files are not always interchangeable between them, so the rev number printed on the board must read 2.1. Many of these boards use a DualBIOS layout with two flash chips, so check which chip is corrupted before reprogramming. Read and save the existing contents with a programmer first, and confirm the image size fits the chip capacity.
