Good with pix and all. A good rule of thumb is all older VT cards work on the 5 volt buss,
The newer "pro VT" works on 5 volt or 3 volt. The older mother
boards are 5 volt only and the newer mother boards are 3 volt.
The buss led is in or very close location on the old or new cards.
Intel had, or may still have some "legacy" mother boards.
