Firmware set for the Acer Aspire E1-431 on the Quanta motherboard DAZQSAMB6F1, containing both the EC (embedded controller) image and the main BIOS according to the name. The RAR is about 2.88 MB. The EC firmware controls power-on, charging, keyboard and fans, so a corrupted EC image can leave the board dead even when the BIOS is fine. Extract the files and write each one to its own chip or region with a programmer. Back up the original contents first and confirm the Quanta board code and image sizes.
