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: HS761 NM-D521. 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.
