Questions about this file

Will this BIOS work on my board?
Only if the board number and revision match: Toshiba Portege Z20T-B-111. 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.
