RAR archive of 6.90 MB for the Quanta-numbered board DAN14HMB8D0, revision D.

The name does not reveal the laptop model or exact contents, which may be schematics, boardview data or a BIOS dump. Extract it and identify each file before use. Match the board number and revision D printed on the PCB, and back up any flash chip before writing an image from it.
