Description
BIOS dump for the Lenovo B50 laptop, supplied as a RAR archive named Lenovo_B50_Touch_ZIWB0_B1_E0_LA.rar, roughly 2.5 MB. The file name suggests a touch-screen variant of the model, but no board number, revision or chip size is listed here, so confirm the board details on your own hardware. 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, back up the original chip contents and check that the board matches the dump.

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: Lenovo B50. 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.
