My voodoo2 accelerator card dosn't apear in the
directX  (Display Tab).
I have winxp and directx 8.1 and the voodo2 is not
listed under the display tab in the DirectX .
But is listed in the device manager and the glide games
can use him and is listed under the Display Settings.

Here is the driver that I use and it is the only driver  founded that works for me (Many other drivers have failed or conflicts with the winxp):

Agreed, jblue, I can tell a normal Forum Poster from a Spammer, and you're beginning to fall in the 2nd Categoty rather quick.

When you post something, make sure you read Postings already answering your question.
