Gigabyte GA-B85M-DS3H-A firmware package for PCB revision 1.0, packed as an 11.2 MB RAR archive. The name states no BIOS version, so check the contents for a dump or update file. Boards on the Intel B85 platform typically use SPI flash that a technician can reprogram with a programmer when the board will not POST. Gigabyte boards with DualBIOS may carry two chips. Confirm the revision marked on the PCB, back up the original contents, and verify the image matches the chip size before flashing.
