BIOS archive for the Lenovo ThinkPad T440, board NM-A052, in a 5.55 MB ZIP. NM-xxxx numbers belong to the scheme used by LCFC, Lenovo's Compal-linked board maker. The name does not say which files are inside, so open it to check whether it carries a full SPI image, separate chip dumps or an EC file. Such images are written with a programmer to revive bricked boards. ThinkPads store serial and UUID data in firmware, so keep the original dump, confirm NM-A052 on the PCB and match image size to chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
