BIOS firmware archive for the Acer Aspire E1-531-4806 laptop, built on the Compal LA-7912P motherboard with the Q5WVH platform code shown in the name. The RAR is 2.88 MB and should be extracted before use; check inside for the dump image and any notes. Compal uses the LA-xxxxP numbering for its boards, so confirm the code silkscreened on the PCB matches before flashing. Read and save the original SPI chip contents with a programmer such as a CH341A first, and make sure the image size equals the chip capacity.
