BIOS image for the HP All-in-One 24, a Quanta-built board numbered DAN73AMB6D0 revision D, in a 6.56 MB ZIP. The trailing 08448 is probably an HP board or system identifier, but the name does not explain it. Quanta uses DA-prefixed board numbers. Use the dump to reprogram the SPI flash when the unit fails to post after corruption, reading and saving the original chip first. Check the board label, revision D and flash chip capacity match 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.
