Lenovo firmware dump tied to motherboard NM-D341, with the additional code HYG60HX4B0 in the name, likely a board label identifier, compressed as a 9.68 MB RAR. NM-D341 follows the LCFC scheme used for Lenovo boards, so verify the exact code and revision silkscreened on the PCB. Technicians write such images to the BIOS SPI flash with a CH341A or similar tool to recover a dead or bricked board. Dump and keep the original chip first and confirm the image size matches its capacity.
