Lenovo UEFI BIOS extract related to the Compal LA-J781P board; the name gives only an address range, 0x001331D0 to 0x009331D0, meaning the region was carved out of a larger file. It will likely not be a ready full-chip image, so check its size against the SPI flash and rebuild a complete dump if needed. No laptop model is stated. Confirm the LA-J781P marking on the PCB and save the original chip contents with a programmer before any write.
