Firmware package for the ASUS B85-PLUS motherboard whose name refers to USB 3.1, most likely a BIOS build for a variant or update involving USB 3.1 support; the archive is a 9.02 MB RAR. The name gives no BIOS version or board revision, so inspect the contents before use. Such images can be flashed through the board's update utility or written straight to the SPI chip with a hardware programmer. Always dump and keep the original chip contents first, and confirm the image size fits the installed flash chip.
