BIOS firmware for the Gigabyte GA-Z68AP-D3 at board revision 2.0, an Intel Z68 desktop motherboard, in a 2.85 MB RAR archive. Gigabyte prints the revision on the PCB, usually near the PCIe slots, and firmware for rev. 2.0 should not be flashed to a rev. 1.0 board. Many Gigabyte boards of this era use dual BIOS chips, so check which one needs programming. Save the original contents first, and confirm the image size matches the flash chip capacity before writing.
