BIOS firmware archive for a Lenovo-style L550 notebook built on the Compal LA-5322P board, with the NSWAA project code in the name. The name also points to chip positions U22 and U13, which most likely refer to the BIOS and EC/KBC flash locations on the board. LA-xxxxP is Compal numbering, so confirm the code printed on the PCB before flashing. Read and save the original chip contents with an SPI programmer first, and check that each image size matches its target chip capacity.
