ACPI_TOSHIBA(4)		    Kernel Interfaces Manual	       ACPI_TOSHIBA(4)

NAME
       acpi_toshiba -- Toshiba HCI interface

SYNOPSIS
       To  compile  this  driver  into the kernel, place the following line in
       your kernel configuration file:

	     device acpi_toshiba

       Alternatively, to load the driver as a module at	boot time,  place  the
       following line in loader.conf(5):

	     acpi_toshiba_load="YES"

DESCRIPTION
       HCI  is	Toshiba's Hardware Control Interface which is somewhat uniform
       across their models.  The acpi_toshiba driver allows the	user to	manip-
       ulate HCI-controlled hardware using a number of sysctl(8) variables.

SYSCTL VARIABLES
       The following sysctls are currently implemented:

       hw.acpi.toshiba.force_fan
	       Causes active cooling to	be forcibly enabled (`1') or  disabled
	       (`0') regardless	of the current temperature.

       hw.acpi.toshiba.video_output
	       Sets the	active display to use according	to a bitwise OR	of the
	       following:

	       0       No display
	       1       LCD
	       2       CRT
	       4       TV-Out

	       Only some systems (i.e.,	the Libretto L5) support video switch-
	       ing  via	 this hardware-specific	driver.	 Use the acpi_video(4)
	       driver for generic video	output support.

       hw.acpi.toshiba.lcd_brightness
	       Makes the LCD backlight brighter	or dimmer (higher  values  are
	       brighter).

       hw.acpi.toshiba.lcd_backlight
	       Turns the LCD backlight on and off.

       hw.acpi.toshiba.cpu_speed
	       Sets the	CPU speed to the specified speed.  This	provides func-
	       tionality  similar  to the hw.acpi.cpu.throttle_state variable.
	       Higher sysctl values mean lower CPU speeds.

       Defaults	for these variables can	be set	in  sysctl.conf(5),  which  is
       parsed at boot-time.

LOADER TUNABLES
       The  hw.acpi.toshiba.enable_fn_keys  tunable  enables  or  disables the
       function	keys on	the keyboard.  Function	keys are enabled by default.

       This  behaviour	can  be	 changed  at  the  loader(8)  prompt   or   in
       loader.conf(5).
