BIOS image for the Acer Aspire E1-531G and E1-571G, built on motherboard LA-7912P. The LA-xxxxP numbering identifies Compal as the board maker. The RAR is 2.88 MB and is meant for reflashing the SPI flash with a programmer to revive boards with corrupted firmware. As one board serves both models, confirm the LA-7912P label and the board revision on your PCB. Back up the original chip before writing and make sure the image size fits the flash.
