Description
BIOS dump for the Lenovo T470 laptop, board NM-A931 revision 2.0 (platform CT470, Compal design), packaged as a 5.8 MB RAR archive. The uploader marked it as tested, though that is their claim and not something the catalog has checked. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Before writing anything, confirm that the board number and revision on your motherboard match NM-A931 rev 2.0, and save a full backup of the original chip contents first.
The catalog also lists 2 schematics and 15 BIOS dumps for board NM-A931.

Questions about this file
How do I flash this BIOS dump?
Write it to the SPI flash chip with a programmer such as the CH341A and a SOIC8 clip. Read and keep the original contents first, and check that the chip size matches the dump.
Will this BIOS work on my board?
Only if the board number and revision match: Lenovo T470 CT470 NM-A931. Dumps from a different board or revision can leave the board dead.
What does “clean ME” mean?
The Intel ME region in the dump has been reset, so it can be used on another board of the same model. Keep your original dump and transfer serial numbers if needed.
