Yes, that's true.  We're somewhat fortunate in that our Legacy I/O
devices are confined to those on the first blade, and all of these
other devices are on other blades (PCI segments 1+).

But you're right, unless the card vendor supplied some kind of strapping
option, or something similar, it won't know it's in a UV system or not.

Thanks,
