Description

From the original post:
Untested

BIOS dump for the ASUS X55U laptop, revision 1.4, packaged as a ZIP archive of about 2.1 MB under the original file name "Asus X55U Rev 1.4 AMD - Bios KBC.zip". The dump includes EC/KBC firmware, so the embedded controller code is part of the package. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. The source caption marks the file as untested, so treat it with caution.

For the ASUS X55U the catalog also has 1 schematic, 3 boardview files, and 2 BIOS dumps.

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: ASUS X55U. 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.
