BIOS dumps for the Lenovo AM4P2MS board, version 1.1, labelled for chip locations U71 and U53 and sized for 16MB flash. The designators tell you which chip on the PCB receives which image, so match them carefully before programming. Use an SPI programmer and read each chip out first to keep a backup. Check that board version 1.1 and the chip capacities match, because a wrong-sized or misplaced image will leave the board unable to boot.
