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 manipulate
     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  switching
	     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 function-
	     ality  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).
