Kazutaka YOKOTA a2fc20d086 A fix/work-around for ThinkPad 535.
Add a new configuration flag, KBD_NORESET (0x20) to tell scprobe() not
to reset the keyboard.

IBM ThinkPad 535 has the `Fn' key with which the user can perform
certain functions in conjunction with other keys. For example, `Fn' +
PageUP/PageDOWN adjust speaker volume, `Fn' + Home/End change
brightness of LCD screen. It can also be used to suspend the system.

It appears that these functions are implemented at the keyboard level
or the keyboard controller level and totally independent from BIOS or
OS.  But, if the keyboard is reset (as is done in scprobe()), they
become unavailable.  (There are other laptops which have similar
functions associated with the `Fn' key. But, they aren't affected by
keyboard reset.)

ThinkPad 535 doesn't have switches or buttons to adjust brightness and
volume, or to put the system into the suspend mode. Therefore, it is
essential to preserve these `Fn' key functions in FreeBSD. The new
flag make scprobe() skip keyboard reset.

If this flag is not set, scprobe() behaves in the same say as before.

(If we only knew a way to detect ThinkPad 535, we could skip keyboard
reset automatically, but...)

This is the top level of the FreeBSD source directory.  This file
was last revised on: $Id$

For copyright information, please see the file COPYRIGHT in this
directory (additional copyright information also exists for some
sources in this tree - please see the specific source directories for
more information).

The Makefile in this directory supports a number of targets for
building components (or all) of the FreeBSD source tree, the most
commonly used one being ``world'', which rebuilds and installs
everything in the FreeBSD system from the source tree except the
kernel.  Please see the top of the Makefile for more information on
the standard build targets and compile-time flags.

Building a kernel with config(8) is a somewhat more involved process,
documentation for which can be found at:
   http://www.freebsd.org/handbook/kernelconfig.html
And in the config(8) man page.

The sample kernel configuration files reside in the sys/i386/conf
sub-directory (assuming that you've installed the kernel sources), the
file named GENERIC being the one used to build your initial installation
kernel.  The file LINT contains entries for all possible devices, not
just those commonly used, and is meant more as a general reference
than an actual kernel configuration file (a kernel built from it
wouldn't even run).
