I have two 3D devices in my system: an ATI Rage Pro chipset, and a 3DFX Voodoo Graphics chipset. How can I select one over the other? I remember there was a program to do this but I can't find it anywhere.

why do you have 2?  is one attached to the motherboard so that you can not remove it?  If so, you will have to disable the one you do not want to use. do this through device manage.  Just disable in current profile.  if you remove it, windows will just find anset it up again the next time you reboot.  if this is not what you mean, please explain further as to what problem you are having,

Well I had the 3DFX card first, and then I got the ATI All In Wonder PRO, which uses the Rage Pro chipset. I would like my system to use the 3DFX hardware acceleration rather than the Rage Pro 3D hardware acceleration by default.
I still need the Rage Pro device, though. The 3DFX card is a 3D-only card--it doesn't do 2D.

OK...I don't know why you  need to switch between them, but there is a way.  Create another hardware profile so that you have two hardware profi;es available.  keep all your other hardware the same in both profiles except for the video cards.  Use the ATi All in wonder in the original profile and the 3dfx card in Configuration #2.  Below is a copied quote from windows help on how to do this.  You will find it under Help>hardware>profile   Use search in help to seach for hardware
Quoted:
To create a hardware profile

  open the System Properties dialog box.
Click the name of the Profile  you want to base the new hardware profile on, and then click Copy.
In To, type a name for the hardware profile you want to create.
Notes
You can also open the System Properties dialog box by clicking Start, pointing to Settings, clicking Control Panel, and then double-clicking System.
When you start Windows, you are prompted to choose the hardware profile in which to start Windows. Windows loads only the device drivers for those hardware devices that are enabled in the profile you choose.
If you have a hardware profile named the same as an MS-DOS multiple configuration menu item, the corresponding menu item will be run automatically when you start in that hardware profile.

End quote

Hope this helps

The reason I need to switch is that the 3DFX 3D acceleration is much faster than the Rage Pro 3D acceleration. What I am looking for is a program or any other way to switch the device that DirectX uses. Sorry for any confusion. It has nothing to do with the Device Manager. I know there is a program for this because I used to have it...I just can't find it anymore.

i dun use any of the above so my advice might be coming from nowhere.. :)

i think that in some games you can run setup which lets you choose which card you want to use.. in some options..

either that or the drivers that comes with your video card should allow you to choose which card to use for directdraw.. like i said.. i think.. :)
