Description
BIOS dump for the Lenovo T420i laptop, supplied for an 8 MB flash chip. The original file name, LENOVO T420i_NZM3I-6_UMA_QM67_U49_25Q64FV.rar, suggests a UMA build on the QM67 platform, though no board number or revision is listed here, so confirm those against your own board first. Technicians use a dump like this to reprogram the SPI flash with a programmer after a corrupted BIOS or a failed update. Read and save the original chip contents before writing anything, and check that the board details match yours before flashing.
The catalog also lists 1 boardview file for the Lenovo T420I.

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 T420I. 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.
