I think the current way of rebooting is rather ugly. If i remember well, cpu_reset() nukes the page table directory(s) or does some other dirty trick causing the cpu to fall over. We should instead use one of the documented methods to reset an AT, e.g. via the keyboard controller. I don't know if any of this will also reset the ISA bus, at least it's much cleaner than only choking the cpu. -- cheers, J"org work: --- no longer --- private: joerg_wunsch@uriah.sax.de Never trust an operating system you don't have sources for. ;-)
