BIOS dump for the Acer 4736 series laptop on the Compal-made LA-4491P motherboard, with Compal identified in the name by its codename Kalho. The 760 KB RAR likely holds a small SPI image typical of that generation. It is written with a programmer when the laptop shows no display or has a corrupted BIOS. Read and keep the original chip contents first. Check that the image size matches the flash chip capacity, and confirm the board number on the PCB is LA-4491P before flashing.
