Firmware for HP HSN-Q31C laptops on Quanta mainboard DA0X9QMB8D0 revision D, bundling separate BIOS and EC dumps in a 20.8 MB RAR. It is listed alongside a near-identically named package of the same size, so compare their contents before choosing one. Technicians reprogram these images with a CH341A or similar programmer to fix boot loops, a dead board after a failed update or EC-related power faults. Verify the board revision, match image sizes to chip capacity, and keep a backup of the original flash.
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.
