It was really just a guess on my part- Everest on my main PC says Internal, (to the card, I suppose) whereas all my laptops say "Integrated"- so I just extended to logic to this PC.
I forgot the Vanta was a standalone card though; Actually I just discovered why I had never heard of it:
A low-cost version, known as the TNT2 M64, was produced with the memory interface reduced from 128-bit to 64-bit. Sometimes these were labeled "Vanta", continuing the Vanta name started with a value-oriented RIVA TNT-based product. This chipset outperformed the older RIVA TNT while being less costly to produce. They proved quite popular in the OEM market, as most consumers simply assumed all TNT2 cards were the same.
turns out it's just a stripped Riva TNT!
