Description

From the original post:
PRINTER L405

The facts identify this as a BIOS dump packed in a RAR archive, about 6.8 MB, with the original file name "PRINTER L405.rar". No brand, board number, revision or chip size is given, and the caption only reads "PRINTER L405", so the target device cannot be confirmed from the listing. A BIOS dump is used to reprogram the SPI flash chip with a programmer after corruption or a failed firmware update.

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: PRINTER L405. 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.
