BIOS for an HP All-in-One 22 desktop using the Quanta DAN14CMB6E0 board, revision E, dated 2019 and sized for a 16MB flash. It comes in a 6.48 MB RAR archive. Quanta DA-series codes are printed on the PCB, so check that the number and revision letter match your unit before programming. Such dumps are used to bring back all-in-ones that show no display or stop at a black screen after a corrupted update. Save the original chip with an SPI programmer first, and confirm the 16MB size 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.
