Stock BIOS dump for Lenovo boards using the ACLU3 and ACLU4 platform codes, motherboard NM-A361, from a unit with a Core i7 and AMD discrete graphics, in a 3.48 MB RAR archive. NM-xxxx is the LCFC numbering used for Lenovo consumer laptops. Stock means an unmodified factory image. Write it to the SPI chip with an external programmer to fix boot failures or corrupted firmware. Boards with integrated-only graphics or other CPUs may need a different image, so confirm the board number and configuration and save the original chip contents first.
