EC firmware for the A716-71G and -51tn variant on Compal board LA-E911P revision 1B, labelled ECE, with the codes C5MMH and C7MMH in the name. At 128 KB it is the embedded controller image, separate from the main BIOS. The controller manages power sequencing, charging and the keyboard, so a bad EC image can leave a board with no power-on. LA- numbers come from Compal. Read the existing chip or controller content first, and make sure the board revision matches before writing.
