I just upgraded my Mobo, but love my 3dfx Voodoo 5500 AGP card (read: don't have the money for a GeForce 3 or 4). It seems the notch in the card doesn't line up with the one in the 4X AGP slot on the Mobo. The original Mobo it came from was a TYAN Trinity 1845, also with a 4X AGP slot. It worked fine in the 1845, but doesn't physically fit in the s2090. Did they make a few different AGP 4 slot configs and I just never got the memo? Any help would be greatly appreciated.
