BIOS image for the Acer Aspire ES1-131, built on the Quanta ZHKD board DAZHKDMB6E0, with ZHKD111 in the name probably marking a firmware version. The RAR archive holds the dump for reflashing the SPI chip with a programmer when the laptop powers on without display or after a failed update. Quanta encodes the project name inside its DA-prefixed board numbers. Back up the existing chip first and confirm both the board marking and the chip capacity match before writing.
