Description

BIOS dump for the LG 20EN33SSA, supplied as a ZIP archive of about 0.2 MB under the original file name LG 20en33ssa=512=W25X40.zip. The file name suggests a 512 setting and a W25X40 flash chip, but the facts do not confirm these details, so check the chip marking on your board before using it. A BIOS dump is used to reprogram the SPI flash with a programmer after a corrupted BIOS or a failed update. Confirm the model and board details match your unit, and save the original chip contents before writing anything.

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: LG 20EN33SSA. 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.
