Working BIOS for an HP all-in-one with an AMD platform, built on Quanta board DAN91CMB6D0, revision D, with an 8MB image. Quanta designs many HP AIO boards and labels them in the DAxxxxMBxx0 format, where N91 is the project code. The file has no listed extension, so treat it as a raw dump for an 8MB SPI chip. Confirm the board code and revision, save the original contents, and verify the image after programming.
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 @bios_laptopomi. 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 →
