Sysprep.inf entry

Hi!
We are busy designing a W2K Pro unattended installation using sysprep v1.1 and DriveImage. we are creating the image on a IDE pc and intend to rollout to IDE and SCSI pc. The image works great on an IDE pc, but on the SCSI pc we get a blue screen with BOOT_DEVICE_INACCESSIBLE error. I know that this means the boot loader cannot read the disk, but we have followed all the guides / white papers etc. and cannot find any mistakes. When checking the sysprep.inf file AFTER running sysprep, I found and entry called [SysprepClean] which was added after the fact by sysprep. Does anybody know what this entry does?
