Hi. Check out Nlite. I have successfully Intergrated my Promise SATA 378 into my normal 32bit windows cd. The biggest problem with trying to do them manually is having to modify the TXTSETUP.SIF file with the correct file ID's and locations. Here is a link to NLite. Nlite Homepage And here is a link with info on manually intergrating the drivers Intergrating RAID drivers I have actually used the method described on manual intergrating drivers to intergrate Si3112 drivers From what i understand the layout of 64bit and 32bit windows disks are much the same, so the information on these pages that refer to the 32bit should also work for the 64bit. Good Luck
