nuhi I did exactly similar things with the intel drivers, and got the same problems. Based on an article on another forum about manually slipstreaming drivers, I then copied them to \$oem\$1\drivers, and made sure that OEM was enabled in nlite. This then worked - XP installed correctly and ran with RAID disks. Although I then had completely different problems with XP complaining about versions of files when I started to install the Intel chipset drivers and other motherboard drivers after XP had installed. These seemed to be related to the hotfixes that had been integrated by nLite. It resulted in USB brcoming nonoperational, and thus mouse and k/b freezing. So I evenetually had to go back to a repair install from a CD with just SP2 slipstreamed with no hotfixes. RPPugh
