Base copy of the 650hp C firmware image, 4.00 MB with no file extension, apparently for an HP 650 series laptop, though the board number and revision are not stated. Technicians flash such dumps onto the BIOS SPI chip when a machine powers on without display or fails after an update. Open the image in a hex editor or UEFI tool to confirm the model, check that the chip is 32 Mbit, and read out and keep the original contents before programming it with an external tool.
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 @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
