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.

"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."
