Description
LENOVO X390 FT491 FX390 NM-B891 REV 1.0 WORKING BIOS 100% BIOS dump for the Lenovo X390 laptop, board number NM-B891, revision 1.0, platform FX390 with Compal as the ODM. The uploader marked it as tested, but that is their own claim and has not been verified here. 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, and back up the original chip contents so you can recover if the flash goes wrong.

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 X390 FX390 NM-B891. 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.
