VALD(4)		       BSD/i386 Kernel Interfaces Manual	       VALD(4)

NAME
     vald — Toshiba Programmable I/O controller

SYNOPSIS
     vald* at acpi?

DESCRIPTION
     Some Toshiba computers have a special I/O controller that handles various
     interface devices.	 This special I/O controller is accessed by the “GHCI”
     ACPI method.  The vald driver provides some support for it.

     The vald driver handles the following hot-keys:

	   Fn+F5  Switch between LCD and External Video output.
	   Fn+F6  Decrease LCD brightness.
	   Fn+F7  Increase LCD brightness.
	   Fn+F8  Switch fan (ON/OFF).

     The vald driver has only been tested on the Libretto L3 and on the
     Portege 3440.

SEE ALSO
     acpi(4)

HISTORY
     The vald driver appeared in NetBSD 1.6.

BUGS
     vald may have problems with X11 when switching between LCD and External
     Video output.
