I can use $OEM$ folder and desactivate "OEM preinstall" in winnt.sif? OemPreinstall=Yes This option is default to No but if you are using the $OEM$ Distribution Folders then it needs to be set to Yes, so that Setup regards this installation as a distribution and copies these files over to the system drive. This occurs at the end of Text-mode Setup. Having OemPreinstall set to Yes will also prevent you from loading RAID/SATA drivers from a floppy disc during textmode setup. The only workaround for that problem is to directly integrate the drivers into the CD, as described here. http://unattended.msfn.org/unattended.xp/view/web/19/ I need F6 to load some SATA drivers
