I have a different problem, but I also have a GeForce 2 MX 200 (see post by Disguise).

What I recommend you should do is firstly update your OS at least to second edition of Win98, which really kicks down on the first edition (from the experience I had with both). Then visit http://www.nvidia.com/view.asp?PAGE=drivers and download the drivers for your OS. There are a list of OS's at the bottom. The latest drivers (at the time of this post) are the Detonator drivers version 28.32 and they are 8.1mb for Win98 (27min at 5.0 kb/s).

If your Jazz still doesn't work, then we can sue nVidia together
