BIOS and keyboard EC firmware for the Acer Nitro AN517-41 on board LA-K581P, packed in a 4.86 MB RAR. The LA-xxxxP numbering is Compal style, so Compal is the ODM. Having both the BIOS and the KBEC image lets you restore the main SPI flash and the embedded controller firmware, which handles power-on, charging and keyboard. Back up the original chips before writing with a programmer, and confirm the board number on the PCB and the image sizes match the chips.
