BIOS image of 16.0 MB labelled with the HP-style assembly number 656561-001, with the words VGA and WHITE in the name. The name does not state the laptop model or board number, so check the part number on your board before using it. VGA probably refers to a discrete-graphics variant, though that is not certain. The size matches a 128 Mbit SPI flash. Back up the original chip with a programmer before writing, because it may contain system-specific data.
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.
