BIOS together with EC firmware for the Dell Latitude E6540, motherboard LA-9411P with the VALA0 project code, supplied as a 6.46 MB RAR archive. LA-xxxxP numbers are the Compal board numbering used for many Dell, HP, Acer and Lenovo designs. The system image is written to the SPI flash with an external programmer such as a CH341A, while the EC part restores keyboard controller behaviour. Dump and save the original chip contents first, and check that each file size matches the capacity of the target flash chip.
