Yeah. I think the first patch should add the new driver, and update the .dsc files to build the new driver. But, don't update the .fdf, so there shouldn't be a functional change to the OVMF output after the first patch. Then the second patch can modify the .dsc and .fdf files to swap out the drivers. -Jordan > - I spotted an incorrect reference to PCI_IO_DEV in a comment (patch #2) > > > > > > > Tests done: > > A.
