Description

From the original post:
FV440 FS441 FS540 NM-C121 REV 1.0 CELERON 4205U 2018-12-12 WORKING BIOS 100%

BIOS dump for a Compal laptop, board number NM-C121, platform FS540, revision 1.0, supplied as a 12.3 MB RAR archive. The uploader marked it as tested. The file name also lists FV440 and FS441 alongside FS540, and mentions a Celeron 4205U and a 2018-12-12 date, but those details come from the file name and are not confirmed separately. A BIOS dump like this is used to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update.

The catalog also lists 3 schematics, 4 boardview files, and 14 BIOS dumps for board NM-C121.

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: FS540 NM-C121. 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.
