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.
