BIOS for the Acer Aspire E5-571G on Compal board LA-B991P, with A5WAH given as the platform code. Compal labels its laptop boards LA-xxxxP, and that code appears on the PCB. The 3.18 MB ZIP is intended for recovering the BIOS chip with a programmer when the laptop does not power on correctly or shows no picture. Check the board number and revision before use. Read and save the existing flash contents, and make sure the image size equals the chip capacity.
