Description
BIOS dump for the Lenovo laptop board NM-A411, revision 1.0, produced by Compal. The original file name refers to the ThinkPad Yoga 900-13ISK, so that is the model this dump is associated with. 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 flashing, confirm that the board number and revision match your motherboard, and back up the original chip contents so you can recover if something 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 NM-A411. 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.
