RAR archive of roughly 5.54 MB with BIOS firmware for an X270, marked new in the name, which probably indicates a newer or updated image compared to other versions, though no version number is given. Technicians write such dumps to the motherboard SPI flash with a programmer to recover a bricked machine. Always back up the existing chip before erasing it, keep the backup separate, and make sure the extracted image matches the chip size exactly. Confirm the board identity on the PCB before relying on this file.
