If you have WINNT.SIF with OemPreinstall=Yes, you can disable billboards by creating an empty file $OEM$\$$\SYSTEM32\WINNTBBU.DLL (when starting setup from CD, use the $OEM$ directory at the root of CD, not \I386\$OEM$). At the end of the text-based setup this file will be copied to the installed system, overwriting the default WINNTBBU.DLL. When the GUI setup loads, it will fail to load WINNTBBU.DLL and fall back to the old setup style. Later during setup the original WINNTBBU.DLL will be restored by SFC, but look of the running setup will not change.
