Is it possible to write an OS that will fit onto a 3 ½" floppy that can then write device drivers for all the devices it discovers on the system and build itself into a fully functional and useful desktop OS? The basic intent is to start out with just a bare-bones OS that can write to a hard drive, whether this requires some hints files or not; a hint file would be one that has a listing of a particular device and its specifications.

Just to make my original thought clear: this OS writes itself. No external help, unless it be through hints files. I'd rather that not be an obnoxious point, but that's part of the challenge.

This challenge may also be construed to be Self-improving genetic programming. See also http://www-ia.hiof.no/~rolando/SIG/ for more details.
