nice tip on the driver tool ricktendo.  i did a quick search on softpedia and found two freeware tools like it at http://www.softpedia.com/get/System/Sys … iver.shtml and http://www.softpedia.com/progDownload/D … -4729.html .  i haven't tried them out yet but they're well-rated.  also, i don't think the DP name scheme you posted will work.  i think it has to be "DP_NAME_wnt5_x86-32_VERSION.7z" not "DP_NAME_wnt5_x86-32.7z"  that's what it took for me to get it working at least.
cheers,
