Firmware binary of 16 MB labelled with HP-style spare part number 656561-001 and tagged VGA White, apparently identifying a motherboard variant with discrete graphics and white chassis trim. No model name is stated, so cross-reference the spare part sticker on the board before use. A full 16 MB image is normally written to the SPI flash with a programmer such as a CH341A after saving the original dump, which preserves serial and system data you may need to restore.
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 @freeschematicdiagram. Enginerys does not host this file.
