Backup of the embedded controller firmware from a Dell board numbered LA-6592P, read from the SMSC MEC5055 EC. LA-xxxxP is the Compal board numbering pattern, and Compal builds many Dell notebooks. The 256 KB binary covers the EC flash, not the main BIOS. It is used when the EC is corrupted and the machine shows no power, charging or keyboard response. Writing it requires a suitable programmer or EC flashing method, and the original contents should always be saved first.
