even when its enabled, the raid functionaliy of the ICH??R chips is 
zero.  :)     "enabling RAID" in the BIOS simply sets a bit in the chip 
thats write-once (once its set, it can't be reset short of a full chip 
reset), this does two things. 

    A) it changes the PCI DEVICE_ID of the chip so it requires different 
drivers,
    B) it tells the BIOS and drivers that they should implement Intel 
Matrix aka fake raid rather than standard SATA JBOD.

thats *ALL* it does in hardware.  nada else.
