tnt2 driver trouble (I think)

[noobii]

I have bought a used tnt2 card, and it works most of the time. However, I have no clue to who made it, and nvidia doesnt have any support so I dont know where to turn.
The problem is, one game (codemasters "insane") tells me that I have to chack the box called "Z-buffer depth equal to rendering depth if unequal". The problem is I dont have this box in my options. Why could this be? I have the latest drivers, but I cant upgrade my bios sonce I dont know who made the card.
I know that maybe this is the wrong place for this question, but I dont know where else to ask :)

If you download Sisoft Sandra and use the information module for the PCI/AGP slots it will tell you the manufactur... usually... then go here http://www.x-bios.3dgames.ru/ for the bios upgrade (you might even want to try the nvidia reference bios). Hope this helped.

Your advice helped, I found the manufacturer, and downloaded a driver from them. That solved the problem, so I wont bother flashing the bios.

Thanks!
