BIOS archive for the Lenovo ThinkPad E470 on the CE470 platform with board NM-A821, revision 2.0, dated 2016-08-25. It is a 4.82 MB RAR. NM-xxxx numbers are used by LCFC, Lenovo's own design arm, for its notebook boards. Technicians write the image to the SPI flash with a hardware programmer when the laptop will not start. Check that the board number and revision match the PCB, read and save the original chip contents first, and confirm that the image size matches the 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.
