You say the box you have says Wonder........
Well the Wonder cards are ATi too, so there''s no doubt that you''ve got an ATi card there.
You just need to get the correct drivers for the card.
I don''t know ATi at all, but if they''re anything like nvidia (don''t hurt me for saying that, it''s a saying

) then they''ll have a driver installation for all of their cards.
Otherwise I suggest you take a look at the card itself inside your machine and look for the chipset ID or device ID which will be printed on the silicon somewhere.
Then either google the ID or look it up on the ati site.
