If there is damage, it will most likely be restricted to the card.

When we cycle through all combinations in one minute, there are about
a hundred PCI cycles per combination left for the chip to be granted
access to the bus. I expect most of the pins to provide a priority
or weighting value for each BT878A, so there should be many combinations
that do something.

Maybe the seller is nice person and provides the contents of the CD for
free.

It's the same card but it is not the Avermedia 4 Eyes Pro.
