BIOS image for a desktop motherboard identified only as HB B85, version V1.11, marked by its source as fully working. The B85 token points to the Intel B85 chipset used with Haswell-generation LGA1150 processors. The RAR archive should contain a raw dump intended for writing straight to the SPI flash chip with a programmer such as a CH341A. Read and save the original chip contents first, confirm the chip capacity matches the image size, and check that the board marking on the PCB is the same before flashing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
