Hi Bâshrat....on this page : http://unattended.msfn.org/xp/drivers.htm It says: "For those who have a SATA/Raid setup, you may want to {Greenmachine's} page as the method outlined below cannot load your Hard drive controller drivers during Setup, nor does F6 work during an unattended installation." Alta: It did turn out to be a BIOS deal. It was set to use RAID, but I am not (just have 1 drive). Now that I turned all that "Fasttrack Controller - BIOS not installed" off, XP did finally see the drive in either of the RAID ports (Promise SATA378), but it still won't see the drive if its in the other 2. (The Intel ones, I guess). So my slipstreamed disk did work, but I guess its the opposite of how yours did! I have no clue why!
