specifically what?

On 4.x you can remove the default flags from they atkbd entry and I
think that will do it. See the atkbd(4) manpage for details. Hot
plugging or unplugging they keyboard can damage the motherboard or
keyboard.

Hi.

I have a large amount of servers, and the problem is, that when I need
to plug a keyboard into them, the keyboard is disabled since they
werent booted with a keyboard.

I was wondering if anyone has some idea of how to disable the keyboard
probe at boot and make it so that the OS thinks that the keyboard is
present even if its not plugged in, so that a keyboard can be plugged
in at any stage, and will function normally.

Im speaking specifically for ps2 keyboards. Is this even possible, or
are there architecture problems or something else relating to this
that would make this impossible?

If this is possible, could someone please point me in the correct
direction as to which code I would need to look at to make this
possible?

What version of FreeBSD are you running? This hasn't been the case by
default for ages. As a warning, PS2 keyboards are not electricaly
designed to be hotplug so you may blow your machine up by doing this
(says someone who does it all the time).
