BIOS dump for the LCFC NM-A551 mainboard, the board used in the Lenovo E460, compressed into a ZIP of about 4.06 MB. The name carries no version, chip or ME status details, so treat it as a generic SPI image for that board. Technicians reflash such dumps with a programmer like CH341A onto the BIOS flash chip to fix boot failures or corrupted firmware. Back up the original chip first, compare the extracted image size with the chip capacity, and expect to restore serial and other machine-specific data afterwards.
