Description

From the original post:
DG425 DG525 DG725 NM-B321 REV 1.0 2017-03-14 WORKING BIOS 100%

BIOS dump for the Compal NM-B321 laptop board, revision 1.0, listed under the DG725 platform. The original file name also references DG425 and DG525, but the uploader's facts tie this dump to DG725, so check your board's platform and number before using it. The uploader marked it as tested, which is their claim and not verified here. A BIOS dump like this is used to reprogram the SPI flash chip with a programmer after a corrupted BIOS or failed update.

For board NM-B321 the catalog also has 2 schematics, 1 boardview file, and 15 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: DG725 NM-B321. 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.
