BIOS archive labelled HDS114 for the Haswell platform, meaning Intel 4th-generation Core processors. The name gives no brand, board number or model, so the target hardware has to be confirmed separately, for example from the board sticker or the current firmware string. It appears to pair with an HDSB114 Broadwell build, and mixing generations can leave a machine dead. Read the existing flash with a programmer and keep that backup before writing. Check the contained file size against the flash chip capacity, since an oversized image will not fit.
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.
