On most machines I have seen, IRQ's are shared between certain "slots". You can change the IRQ that is being used but not the devices sharing it. I believe this is inherent to the current PC architecture and motherboard design. Being that the NIC is integrated and you have so many other IRQ's free, I'm not sure why they chose that route for your board. Perhaps NICs can generally share with video cards without problems. In general (not guaranteed), devices *should* be able to share IRQ's if the drivers are written properly and if the hardware isn't designed horribly. This is just a generalization of my own experiences. I in no way write drivers for hardware for any operating system. YMMV. :) Vinny Abello Network Engineer Server Management vinny@tellurian.com (973)300-9211 x 125 (973)940-6125 (Direct) PGP Key Fingerprint: 3BC5 9A48 FC78 03D3 82E0 E935 5325 FBCB 0100 977A Tellurian Networks - The Ultimate Internet Connection http://www.tellurian.com (888)TELLURIAN "Courage is resistance to fear, mastery of fear - not absence of fear" -- Mark Twain
