Description
E480 EE580 NM-B421 REV 1.0 2017-10-30 BIOS & EC BIOS dump for a laptop built on the Compal NM-B421 board (platform EE580), revision 1.0, packaged as a RAR archive of about 5.2 MB. The archive also includes EC/KBC firmware, so it covers the embedded controller alongside the BIOS. 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 NM-B421 and revision 1.0 match your motherboard, and back up the original chip contents first.
For board NM-B421 the catalog also has 2 schematics, 3 boardview files, and 8 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: EE580 NM-B421. 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.
