o too many changes to mention specifically, but amongst them: - better error reporting - openbsd boots, freebsd boots - new 'term' flavor, I added a textmode interface, the only drawback is that control-c is intercepted, and you must kill -9 it from another tty if it doesn't exit normally - new flavors: - debugger -> debug (for shortness) - i386 - pci - smp - net (compiles, does not yet provide networking, if anyone wants to help, I'd be ELATED to have this fixed!) - no_x11 (made it actually work) - term (make sure to use 'log: /dev/null' or something else on the cmdline, otherwise, debugging and the screen will start getting quite confusing!) - better error reporting (and no error reporting where it is not necessary; a typicall boot of cdrom28.fs is a screenful of output now) - in general, if the hardware reaches an unknown state, fail gracefully instead of calling exit(1) .. are we trying to work or are we trying to .. fail? I like working myself.
