What kind of hardware feature would exist for accelerating RAID-0?  
They don't have an I/O processor down on the board, do they?  (I would 
be surprised; those are generally for accelerating RAID-5).

I suspect what it really means is "BIOSes for these chipsets have some 
RAID-0 software in them".
