Description
LENOVO ThinkPad X13 GEN 1 NM-C891 1.0 INTEL i5-10210U BIOS & 1M TYPE-C WORKING BIOS 100% BIOS dump for the Lenovo laptop board NM-C891, an ODM design from Compal, supplied as a 1 MB chip image in a RAR archive of about 41.4 MB. The original file name points to a ThinkPad X13 Gen 1 with revision 1.0. The uploader marks it as tested, but that is their claim and has not been verified here. Technicians use a dump like this to reprogram the SPI flash with a programmer after BIOS corruption or a failed update. Confirm that the board number and revision match yours, and back up the original chip contents before writing.
For board NM-C891 the catalog also has 1 schematic, 1 boardview file, and 3 BIOS dumps.

How do I flash this BIOS dump?

Will this BIOS work on my board?
Only if the board number and revision match: Lenovo NM-C891. 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.
