Quanta board DA0ZQRMB6C0 revision C firmware, including both BIOS and KBEC images reported as fully working. The name does not identify the laptop brand, but the DA0 prefix marks a Quanta-designed mainboard. Keyboard EC firmware is stored separately on such designs, and restoring it can cure no-power or dead-keyboard faults. The 2.25 MB RAR is for use with an SPI programmer. Confirm the PCB revision matches, and read and keep the original chips before writing.
