Description
BIOS dump for a laptop motherboard, board number NM-B321, revision 1, produced by Compal. The original file name notes "TEST OK", though the catalog does not verify that claim. Technicians use a dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Before writing anything, confirm that the board number and revision on your board match this file, and save a backup of the original chip contents first. The archive is a 4.5 MB RAR.
The catalog also lists 2 schematics, 1 boardview file, and 15 BIOS dumps for board NM-B321.

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-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.
