BIOS archive for an HP device identified by TPN-Q214, on Quanta board DAG7DCMB8D0, revision D, labelled as working. HP's TPN regulatory code identifies the chassis, while the DA-prefixed number follows Quanta's board scheme, with the revision letter printed on the PCB. At 43.7 MB the archive probably holds more than a single SPI image, so check its contents and choose the file whose size matches the flash chip. Back up the original chip with a programmer before writing.
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 @biosarchive. Enginerys does not host this file.
