Description
This is a BIOS dump for a laptop motherboard with board number NM-B021, platform DL470, built by Compal. The original file name points to a Lenovo ThinkPad L470, so the board is likely the one used in that model, though the facts do not confirm the exact match. The archive is a ZIP of about 7.7 MB. A BIOS dump is used to reprogram the SPI flash chip with a programmer after corruption or a failed update. Before flashing, confirm that the board number and revision on your board match, and back up the original chip contents first.
The catalog also lists 1 schematic, 1 boardview file, and 6 BIOS dumps for board NM-B021.

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: DL470 NM-B021. 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.
