BIOS dump for the HP ProBook 6475B laptop, delivered as a ZIP archive of about 2.6 MB under the original file name Rom68RTU add dmi.zip. The file is meant for reprogramming the SPI flash chip with a programmer after a corrupted BIOS or a failed update. The facts do not list a board number, revision, chip size or whether the Intel ME region is cleaned, so check the board number and revision on your own motherboard against the dump before flashing.

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: HP ProBook 6475B. 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.
