Firmware image for the Gigabyte GA-B85-HD3 motherboard covering the 1.x revisions, delivered in a 9.5 MB RAR. Technicians use such a file to recover a board with corrupted BIOS by programming the SPI flash with a CH341A or similar tool. Gigabyte boards may carry main and backup BIOS chips, so identify the correct one. Separate images exist for revisions 2.0 and 2.1, so confirm the PCB shows a 1.x revision, save the original dump first and check the size matches the chip.
