I'm eventually going to switch my retro rig from Windows 95 to pure DOS. The problem is that it currently has an 80gb drive that I managed to get 95 to work on. I had to put DOS 7 on it and install everything a funny way, but it uses the whole drive.

I want to use DOS 6.22, or 6.0, because my school's MSDN Academic Alliance page had them. What's the largest physical drive that I can use, and what's the best way to partition it? I would really like to rip CD-based games to HDD, but it's not absolutely necessary.
