Windows 2000 build 1729

Build 1729 changes many parts of the setup. TXT setup no longer detects the IDE drivers during this portion of setup, and has an option to restore a destroyed disk. The GUI setup also changes to be more resentment to that of Windows 2000. MSN is also updated to version 2.5 (which doesn't work as it loads a webpage that has been taken down). Unlike the other beta 1 builds, it has no timebomb.
