1. Fix a few bugs in the ftp installation code and implement proper ftp and network shutdown routines. 2. Clean up the menus a fair bit - add a FreeBSD configuration menu. 3. Eliminate the last of the "chaining" - the installation now does the most obvious thing in the most obvious cases and doesn't present you with more menus than you were expecting. This makes it necessary to be a little more explicit in places, but it's still less confusing. 4. Add a few more safety nets for the user. Change a few hard-and-fast limits to warnings (it now runs as non-root, Bruce). 5. Add descriptions for all the supported ethernet cards. 6. Make the cpio floppy extract put up a menu requesting the drive you wish to use if you have more than one; don't just always assume drive A.
