BIOS dump for the Lenovo ThinkPad T460 using motherboard NM-A581 revision 2.0, stored as a .bin inside a ZIP archive. Board numbers of this NM-A pattern are issued by LCFC, the Lenovo-owned design house. Technicians write such images to the SPI flash to recover a board with corrupted firmware or a supervisor lock. Back up the existing chip first, then confirm the revision printed on the PCB and the flash capacity. An image of the wrong size will not fit the chip correctly.
