Description
BIOS dump file, 16 MB flash chip size, delivered as a BIN file named 640 g1.BIN (about 16.0 MB). The facts do not name a brand, model or board number, so confirm the target machine before using it. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after BIOS corruption or a failed update. Before writing anything, read and save the original chip contents as a backup, and verify that the board number and revision of your laptop match the dump's intended platform.

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: 640 g1. 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.
