EC firmware for the Acer 4349 on Quanta board DA0ZQRMB6C0, revision C, a 128 KB binary. DA0...MB codes follow Quanta's numbering scheme. The embedded controller handles power sequencing, the keyboard, battery charging and fans, so a corrupt EC image can cause no-power faults. Check the board number and revision on the PCB before writing it. Find out whether your board keeps EC code in a separate chip or in the shared BIOS flash, and back up the original first.
