Description
BIOS dump for the Lenovo ThinkPad T450 laptop, board number NM-A251, revision 1.0, built by Compal. The package includes EC/KBC firmware alongside the BIOS image, so both can be restored from one set of files. Technicians use a 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 match your motherboard before flashing, and save the original chip contents first so you have a way back if the write goes wrong.
The catalog also lists 3 schematics, 1 boardview file, and 10 BIOS dumps for board NM-A251.

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 ThinkPad T450 NM-A251. 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.
