Firmware package for an Acer B5W11 motherboard, Compal board LA-E061P revision 1.0, containing both the BIOS and the embedded controller firmware and marked as working. The LA-xxxxP code is Compal's numbering, so the matching schematic and boardview will carry the same number. Use the BIOS image to reflash the SPI chip with a programmer such as a CH341A, and the EC file for the keyboard controller if it is corrupt. Read and save the original chip contents first, and check the image size against the flash chip capacity.
