Raw 8 MB BIN firmware for the Dell Inspiron 15 5558, motherboard AAL10 with Compal board number LA-B843P. The LA-xxxxP pattern is Compal numbering, and AAL10 is the project code used on the PCB. An 8 MB image corresponds to a 64 Mbit SPI chip and can be written directly with a programmer such as CH341A or RT809H. Back up the original chip first to preserve the service tag and system data, and verify the board number and flash size before writing.
