the "Dell" disk will have all the drivers for your dell computer, install/restore and you're ready to go..
the 2K disk will install, but you will probably have to download/install drivers for various items (sound/display/modem etc)
I have a win 2k restore disk that says it is only for a Dell computer. I also have a disk with win 2K on it. I guess you could say it is for anything else. It is a full verison. What is the difference? Could I use the full verison on the Dell? It is not a big deal to me just was wondering.
