actually, the best method is to go get an 8GB usb key, extract the files from the ISO using an iso file extractor, then copy the files to the USB key and run it from there. 
Dell just came out with the new Server Update Utility [URL] It's on 4 .iso's. The instructions say to concatenate the 4 files into a single .iso file, and then burn it to a DVD.  However, the resulting .iso file is 6.14 GB, and none of our Dell servers can handle a DVD larger than the standard 4.7 GB.   How can we update our Dell servers with current drivers? .. Geoff
