Gigabyte GA-H81M-DS2 BIOS firmware for board revision 3.0, packed in a 2.88 MB ZIP. Use only on boards whose silkscreen shows rev 3.0, since images for other revisions of this model may not suit the hardware. A technician uses such firmware to recover from a failed update or corrupted flash, writing the image either with a hardware programmer or with the vendor utility. Read and save the original chip contents first, and make sure the image size matches the installed SPI flash.
