BIOS firmware archive for the Gigabyte GA-B85M-DS3H, a micro-ATX desktop motherboard for the Intel B85 chipset, for PCB version 3.0. Gigabyte prints the revision on the board near the slots, so read it before flashing, as images differ between versions. The 5.62 MB RAR should hold a dump for an external programmer. Save the current chip contents first, and check that the image size matches the SPI chip so it fits and the board can be recovered after a failed update.
