Firmware package for the Acer Aspire ES1-533 on Compal motherboard LA-D641P. Compal's LA-xxxxP numbering identifies the board design, and the same laptop can ship on different boards, so match the code printed on the PCB. The 3.86 MB ZIP is meant for restoring the SPI BIOS with a hardware programmer when the machine fails to start or loops. Read and save the original chip first, and confirm the image size matches the flash capacity before writing.
