HP firmware archive labelled X8M-8L, a 17.7 MB RAR; the name gives no model, board revision or BIOS version, so its exact target cannot be confirmed from the label alone. Open the archive to check whether it holds a raw SPI dump, possibly with EC firmware, or an HP update package. A raw image is written to the flash chip with a programmer to revive a dead board. Match it to the board markings, save a copy of the original chip, and confirm the image size equals the chip capacity.
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 @efibios. 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 →
