Description
BIOS dump for the Dell XPS 15Z laptop, board LA-7851P from Compal, marked as tested by the uploader and including EC/KBC firmware. Technicians use a dump like this to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update, and the bundled EC/KBC firmware can matter when the embedded controller is part of the problem. The uploader's own label claims the set works, but that has not been checked here.
For board LA-7851P the catalog also has 1 schematic 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: Dell XPS 15Z LA-7851P. 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.
