Yeah, unfortunately, Macintosh Garden can't afford the storage or bandwidth to host large files. A lot of stuff is gone now because of MegaUpload getting shut down, and the people who originally uploaded it never provided a new copy.
Maximum file size, btw, is 400MB.
The thing that grinds my gears about Driver Guide is the fact that they force Windows users to use a very scammy "downloader" with a total of five attempts to trick you into installing crapware. If you switch your browser user agent to a different OS, you can download the file directly.
