I've been trying to set up a network on my computer, so I bought a PCI ethernet card. A Realtek RTL8139D to be exact. Whenever I install it into a PCI slot, my computer is unable to find my Ensoniq AudioPCI 64 card. I've tried moving the card to other slots but nothing works. Every time I remove the card, the sound card and dial-up modem function exactly as they should. For whatever reason whenever I have the ethernet card plugged in, the computer is unable to find the sound card. Even when I boot into Windows 98, it still doesn't work. Any suggestions?
