Strip out sensitive information from BIOS dump

While debugging or rever开发者_如何学Cse engineering a BIOS, what should be removed before sending a dump to someone else?

• Obviously, the serial number can easily be changed using a hex editor and searching for it in ascii (or unicode) string.
• The BIOS password, if set, is probably in plain text too.

What else would be important to remove? What else in a BIOS could be useful to a 3rd party?

What are you trying to protect yourself from? If you were, for example, doing a secure system, you just wouldn't send it -- who knows what might have been encoded covertly?

Removing the serial number and the BIOS password, if any, and you should be fine.

TPM keys and such are not stored in the BIOS (obviously).
