Backup dump taken from the Lenovo CG412 mainboard, LCFC NM-B102 revision 1.0, packed as a 3.95 MB RAR archive. A backup read from a working unit is useful for restoring a board whose SPI flash is corrupted or blank. Keep in mind that it may carry the donor machine's serial number and other identity data. Program it with an external flash programmer, and first check that the image size matches the chip capacity. Confirm the NM-B102 marking and revision on the board. Always save the current chip contents first.
