Description
BIOS dump for the Lenovo T460S laptop, board number NM-A421, revision 3.0, platform BT460 and built by Compal. The uploader marked it as tested, though that is their own claim and not something this 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. Confirm that the board number and revision on your motherboard match before flashing, and read out and save the original chip contents first so you can restore them if something goes wrong.
For board NM-A421 the catalog also has 3 schematics and 7 BIOS dumps.

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 T460S BT460 NM-A421. 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.
