Yeah, I saw something about "physmap" in one web page.  The module was
not available on my system, but it looks like its in the source code,
which means RedHat did not have it configured to build.  I can work

No its just a flash chip soldered on the board, that they call a
firmware hub, because the intent of the mother board manufacturer was
to place BIOS in it.
