DVD PLAYBACK

I am trying to configure a Voodoo 2 graphics card (pci). It is connected to a standard vga card (pci) via a loop-through cable. Under Win98SE, the display adaptor is shown as standard (16colours etc). The Voodoo 2 is shown under Sound, Video and Game Contollers.

How may I change the display adaptor to accept the Voodoo?

Mobo is Microstar 5182, on board Agp 8mb Ati graphics chip. Disabled in bios, in favour of the pci graphics.

AMD K6 2 500
