Description

From the original post:
AAP21 LA-C912P UH4 UE2 UT2 UT5 KBEC

BIOS dump for a laptop on the Compal LA-C912P board (platform AAP21), delivered as a RAR archive of about 5.6 MB that includes the EC/KBC firmware. Technicians use a BIOS dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update, and the bundled keyboard controller firmware can matter when the EC is also affected. Before flashing, confirm that the board number and revision match your machine, and read out and save the original chip contents as a backup.

The catalog also lists 2 schematics, 2 boardview files, and 5 BIOS dumps for board LA-C912P.

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: AAP21 LA-C912P. 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.
