Description

From the original post:
FT491 FX390 NM-B891 REV 1.0 i7-8th Gen 32MB WORKING BIOS 100%

BIOS dump for a laptop built on the Compal NM-B891 board, platform FX390, PCB revision 1.0. The file is supplied for a 32 MB flash chip and is marked as tested by the uploader, which is a claim from the uploader rather than a verified result. Technicians use a BIOS 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 motherboard match NM-B891 and 1.0, and save the original chip contents as a backup.

For board NM-B891 the catalog also has 1 schematic, 1 boardview file, and 11 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: FX390 NM-B891. 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.
