BIOS file for the Gigabyte B85M-D3V-A, an Intel B85 micro-ATX desktop motherboard, labelled as a fully working image. The RAR is 5.55 MB, consistent with an 8 MB flash image inside. Technicians use it to reprogram the SPI chip with a CH341A or similar tool when a board fails to post after a bad update. Many Gigabyte boards of this type use dual BIOS chips, so check which one is being written. Back up the existing contents first and confirm the board revision on the PCB.
