WindowsXP SP2 unattended install with Winnt.exe

Help with Unattend installs

I have a brand new Dell computer. My goal is to do a WindowsXP SP2 unattended install on top of the NTFS image that ships from Dell. Can this be done ? I have been trying it with this command from a secondary hard drive I installed (d drive): d:\i386\Winnt.exe /s:d:\i386 /rx:d:\temp /t:d: /u:d:\i386\winnt.sif .

When I run this I get an error stating that "unable to locate a drive with the required amount of free space". The Dell NTFS partition does not a drive letter at the start of this command. If I give it a drive letter then I will lose the Dell factory image. Here is the contents of my Winnt.sif:
