Description
BIOS dump for a laptop board numbered NM-B451, revision 1.0, from Compal, supplied as a ZIP archive of about 5.1 MB. The original file name references the Lenovo IdeaPad 330-15IKB and several EG-series models, so check your exact model against the board number and revision before using it. A BIOS dump like this is used to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Read and save the original chip contents first so you can restore them if the write goes wrong.
For board NM-B451 the catalog also has 3 schematics, 3 boardview files, and 7 BIOS dumps.

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: NM-B451. 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.
