BIOS archive for the Acer Aspire E5-473G, board code A4WAB, Compal motherboard LA-C341P; no brand or revision is named beyond these. Compal uses LA- numbers for its board designs, and A4WAB is the project code. The 3.84 MB RAR contains the firmware image. It is used to reprogram the SPI BIOS chip with a hardware programmer when the laptop shows no display or loops at startup. Verify the board number on the PCB, keep the original dump, and confirm the image fits the chip.
