After several emails and questioning about 3ware support for the 7506-4LP series cards (not the 7500-4LP). I can report that it works like a charm in 4.8. I have a raid-1 setup using the 3dmd tool on a 2.8 Ghz dual tyan-tiger with 1.5GB mem and 60GB hd's. Just an FYI for those who are in the market for a 3ware card. -Bob
