ZIP archive of 63.3 KB named only EC, so the device, board and version are not stated. The name and small size suggest embedded controller firmware, which handles power sequencing, keyboard, battery charging and fans on laptops. Open the archive and look for a readme, model string or board number inside the binary before use. EC chips are often separate from the main BIOS flash, and writing the wrong image can leave the board dead, so back up the original first.
