actually this method works for slipstreaming sata driver with it.... i dun use OemPnPDriversPath=DRIVERS\ in winnt.sif or copy any sata on my harddisk... i just edit the txtsetup.sif for hardware stuff ... and copy some nvraid.SY_ , VIAMRAID.SY_ SI3132.SY_ IASTOR.SY_ in the i386 folder and everything is install well... just let who dunno about it only... =) Cheers
