That message means just what it says... there is no hardware on the system
that driver recognizes.  It's probably not the right one, but it was worth
a try.

Most on-board devices are still PCI based, so it usually doesn't matter if
the chipset is on a card or nestled onto the mainboard, and the error

driver, and no one at IBM or in the community has felt the pain yet.
Keep bothering IBM, at least until they tell you which chipset is being
