>> (Incidentally, removing the syscons driver causes a sig12, page fault >> while in kernel mode when one continues booting)). Oops, switching from sc0/pcvt to a serial console is currently broken. When the highest priority console device is disabled (or a higher priority one is disabled) the next highest priority one is supposed to take over. If all console devices are disabled, you are supposed to get what you asked for - no console device. Only a few devices support consoles (this is a bug). Their priorities are: syscons pcvt sio0 >You can blame(?) Bruce for that; he insisted on being able to have both >syscons and pcvt in the same kernel so it had to be possible to disable >them. I don't like it for exactly the reason you've noted. It should be possible to disable any driver. It is possible to disable any isa driver. Bruce
