BIOS for the Gigabyte GA-B85-HD3 desktop motherboard, revision 2.1, packed in a 5.6 MB RAR. This Intel B85 board stores firmware on an SPI flash chip that can be rewritten with an external programmer when the board fails to post. Gigabyte boards often use dual BIOS, so check which chip needs writing. Match the revision on the PCB to 2.1, back up the existing contents first, and confirm the image size equals the installed chip capacity.
