I have been preinstalling M$ products for years. I create the very CD\'s you are all talking about. I can gather some of my info, and post it when I get time. Here is an example of an unattend.txt that is set to load a third party SCSI, and run some reg merges, and other batch files during install. Remeber you need to include the [OemBootFiles] section too when using 3rd party scsi. and they must be in the $oem$textmode folder.
