Jordan K. Hubbard f10eb488f6 1. Fix a pathological bug I introduced in msgInfo(). Right idea, wrong
implementation.

2. Totally rework device registration.  It's about half the size and
   more powerful now.

3. Add DOS discovery.

4. Start filling in some of the strategy routines.

5. Another clean-up pass over the menus.

6. Make wizard code use Disk typedef.

If I can get the first strategy routine finished tonite, we should have a working
install (from ftp, at least) this weekend.
