BIOS and EC firmware for an Acer laptop on Quanta board DA0ZQ9MB6C0 revision C, in a 3.64 MB RAR archive marked as 100% working. Quanta DA0-style numbers carry the project code ZQ9 and the revision, which should match the PCB marking. Use an SPI programmer to read and save the original chip before writing, confirm its capacity matches the image, then program and verify. The EC part restores keyboard and power-management functions.
