There is a very poor D3D driver for Voodoo 2. Even passthrough wont work, you need a second monitor.
You can get the driver at 3dfx gamers

Installation Instructions
NOTE : Windows 2000 does not support the passthrough feature of the Voodoo2. The card must be installed in the same way as you would install a secondary 2d/3d board in a multi-monitor setup.
** DO NOT ATTEMPT INSTALL THE CARD AS A MULTIMEDIA DEVICE. **
Run the self-extracting executable.
Power off the system and insert the Voodoo2 card in a free PCI slot.
Power on the system.
Windows will report that it has detected new hardware.
The 'Found New Hardware Wizard' should now appear.
Click the Next Button.
Choose the second option to display the list of known drivers.
On the next page select 'Display adapters' as the type of hardware that you wish to install.
Click 'Have Disk' and enter the location where the driver files were extracted to in Step1.
When asked to choose a device select '3dfx Voodoo2'.
Windows will bring up a number of Dialog Boxes which will ask you to confirm that you want to install the driver. Answer yes to all of these.
Windows will now copy the drivers.
Bring up Display Properties->Settings and enable the Voodoo2 as part of your desktop.
I think lauri mixed both drivers by installing the glide driver and then the d3d driver.
