Description
BIOS dump for a Sony laptop, board number MBX-252, supplied as a ZIP archive of about 1.0 MB. The original file name references PCG-71C11M (VPCEL3S1E) and an AMD Z50-BR motherboard, so those model identifiers come from the file name rather than a verified listing. A BIOS dump is used to reprogram the SPI flash chip with a programmer after a corrupted BIOS or a failed update. Before writing anything, confirm that the board number and revision on your motherboard match MBX-252, and back up the original chip contents first.
The catalog also lists 1 schematic and 2 BIOS dumps for board MBX-252.

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: Sony MBX-252. 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.
