Even Debian has given up on real 386 systems at this point, primarily because system libraries like glibc have; 486 and better represents the bare minimum required at this point. I don't know of any distributions supporting real 386 systems at this point, and doing so would represent a major undertaking. - Josh Triplett -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
