Firmware bundle for the Acer Aspire A315-53 on Compal board LA-E891P, project C5V01, containing BIOS, EC and keyboard-related firmware according to the name, in a 6.35 MB rar. The EC and KB files cover the embedded controller, which handles power sequencing, charging and keyboard scanning. Program each file to its correct chip with an SPI programmer. Read and preserve the original contents beforehand, confirm the board number on the PCB, and verify each image size matches its target flash device.
