BIOS archive named for a B85H3-M4 motherboard, marked v2, 5.05 MB in RAR format. No brand is stated, and the B85 token suggests an Intel B85 chipset board, but check the contents to confirm. The v2 likely refers to the board revision, which should match the marking on the PCB. Use the image to reflash the BIOS chip with a programmer when the board will not POST. Save a backup of the original chip and make sure the image size equals the chip capacity.
