BIOS image for the Acer Predator Helios 300 G3-571 with the Compal LA-E921P mainboard. Compal designs carry LA-xxxxP numbers, so the PCB label, not the Acer model name, is the reference. The file is intended for writing the SPI flash with an external programmer when the laptop powers on without display or the firmware is corrupted. Read and save the original chip first, because it may hold the serial number and system data. Confirm that the image size equals the flash chip capacity.
