How to view/edit Intel CRID (Compatibility Revision ID)...?

    many "Sandy Bridge" notebooks come with Intel's CRID (compatibility revision ID) enabled in the BIOS, which modifies the chipset's PCI identifiers to disguise it as the faulty B2 stepping for compatibility reasons (i.e. to make the preinstalled Windows images work that were created prior to the discovery of the SATA bug).

    Now I'm curious how/where this is actually implemented in the BIOS, and how it could be edited - I'd like to remove that superfluous "disguise" as a faulty chipset, if it's not too much of a hassle.

    I've obtained the latest BIOS ROM for my Samsung RF711 and taken it apart using Andy's tool, but I don't really know what to look for. In fact, I don't even know if the CRID would be a BIOS "part" or "setting".

    Does anyone have an idea what to look for?
