I try to add Raid/Sata slipstream into xp for my new Toshiba laptop without floppy, all i did is:
under task selection press drivers and bootable ISO
insert 1 driver (intel ich8r/ich9r sata raid controller) from floppy
it successful loaded OS, once you try to add new hardware or run Microsoft update, then always popup "Insert your Windows XP Professinal Service Pack 2 CD new".
I was installed nLite v1.4 on one of my Chinese XP Pro system and ran slipstream, I rework again on Englisht XP Pro I got it to work!
This is a bug for nLite running on Chinese Windows only!!!
