The keyboard controller atkbdc provides
I/O services for the AT keyboard and PS/2 mouse style pointing devices. This
controller is required for the keyboard driver atkbd
and the PS/2 pointing device driver psm.
There can be only one atkbdc device
configured in the system.
The following kernel configuration options can be used to control
the atkbdc driver. They may be set in the kernel
configuration file (see config(8)).
atkbd and the pointing device
driver psm may ask the
atkbdc driver to reset these devices during the
boot process. It sometimes takes a long time before these devices respond
to the reset command. These options control how long the
atkbdc driver should wait before eventually giving
up -- the driver will wait X *
Y msecs at most. If the drivers seem unable to
detect devices, you may want to increase these values. The default values
are 200 msec for X and 5 for
Y.The atkbdc driver first appeared in
FreeBSD 3.1. It is based on the kbdio module in
FreeBSD 2.2.
The kbdio module, the atkbdc driver and
this manual page were written by Kazutaka Yokota
<yokota@FreeBSD.org>.
