Description

From the original post:
CANON PRINTER E404

The file is listed as a BIOS dump, but the facts give no brand-matched board number, revision, chip size or platform, and the original file name refers to a Canon E404 printer rather than a laptop or motherboard. Because the board number and revision are unknown, a technician should not assume it fits any particular motherboard. Before using it, confirm the device the dump was taken from, compare it against the chip and board you are working on, and back up the original SPI flash contents before any write.

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: CANON PRINTER E404. 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.
