Zip archive of 677 KB holding BIOS firmware for the Dell Latitude E6430, made for the Compal LA-7782P system board and labelled with a CD3301 prefix. The LA-number pattern identifies Compal as the board maker rather than Dell itself. Such a dump is typically written to the SPI flash with a CH341A-style programmer when a laptop no longer posts after a failed update. Before writing, match LA-7782P on the PCB, keep a copy of the existing chip contents, and confirm the file size equals the chip capacity.
