There are two different firmware options. The "IT" firmware disables the integrated RAID and makes them true HBAs; the "IR" firmware activates the integrated RAID. Buy the cards, flash 'em with the IT firmware and you're good to go. -- Dave Pooser Cat-Herder-in-Chief, Pooserville.com "There are two novels that can change a bookish 14-year-old's life: _The Lord of the Rings_ and _Atlas Shrugged_. One is a childish fantasy that often engenders a lifelong obsession with its unbelievable heroes, leading to an emotionally stunted, socially crippled adulthood, unable to deal with the real world. The other, of course, involves orcs." --John Rogers
