BIOS file for the original revision 1.0 of the Gigabyte GA-EP31-DS3L motherboard, slightly smaller than the dumps for later revisions of the same model. Use it to restore a board that powers on with no POST or that was damaged by a failed update, writing it to the flash chip with a programmer. Since Gigabyte revisions can differ in flash chip and layout, confirm the board reads rev 1.0. Read and back up the existing chip, and check that the image size matches its capacity, since a file that is too large will not fit.
