Hi Li,
It looks like the standalone MM version of this library is missing the search
for the BiosId file. I suspect the issue you ran into is that standalone MM
only has support for 1 FV, and it is highly likely that the BiosId file is not
in the standalone MM FV. This is understandable; however, it does highlight yet
another deficiency in the architecture of standalone MM. Again, that is not
your fault and is beyond the scope of this patch.
