Description
EG521EG522EZ511EG721 NM-B451 REV 1.0 2017-06-26 i5-8250U WORKING BIOS 100% BIOS dump for the Compal NM-B451 laptop board, revision 1.0, supplied as a 6.1 MB RAR archive with a cleaned Intel ME region and a fast boot option. The uploader marks it as tested, though that is their claim and not something the catalog has checked. Technicians use a dump like this to reprogram the SPI flash with a programmer after a corrupted BIOS or a failed update. Before flashing, confirm that the board number and revision match your board, and save the original chip contents as a backup so you can restore them if needed.
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.
