NAME
toshset - manipulate bios and hardware settings of Toshiba laptops
SYNOPSIS
toshset [TOGGLEOPTIONS | QUERYOPTIONS | FEATUREOPTIONS]...
DESCRIPTION
Toshset ia a command-line tool to allow access to much of the Toshiba
hardware interface developed by Jonathan Buzzard. It can do things like
set the hard drive spin-down time, turn off the display and set the fan
speed.
Credit for the difficult task of reverse-engineering the Toshiba
hardware interface goes to Jonathan Buzzard. A link for Jonathan’s
tools is http://www.buzzard.org.uk/toshiba/
All options are listed by running toshset with no arguments.
If an argument option is specified as the ‘‘-’’ character, stdin is
read for that option. This is particularly convenient when setting the
owner string.
The method used for access to the laptop hardware is given by the the
HCI/SCI access mode query field. This should be kernel or direct. The
kernel method requires kernel support and it is the only access method
supported for ACPI kernels. If ACPI is not used this package does not
require a special kernel module. Also, it is highly likely that this
tool will work under different flavors of *NIX. As a result of this
design consideration, and because of my own desire that not every user
be able to change my laptop’s hardware settings, the user must have
read/write permission to /dev/toshiba in order for this program to run
properly.
Toggle Options:
-l toggle long query in which the assocated command-line option is
printed with each queried feature.
-fast run in fast mode: a startup check is skipped, and values are not
queried after the are set. On machines for which ioctl is slow,
this can speed toshset up by up to a factor of 2/5.
-v toggle verbose mode in which normally silent messages are
printed.
Query Options:
-q [glob]
query features specified by glob (all features if glob omitted).
The glob string is sandwiched between asterisks, so specifying
-q bat will query all features whose names contain the ‘‘bat’’
substring. If no glob is given, then all features are queried.
Feature Options:
Valid settings for features can be listed by omitting the argument. The
current list of feature options is
-b <off|on>
enable/disable system beep
-lcd <setting>
set lcd brightness.
-inten <setting>
set lcd brightness. Not all models support both -lcd and -inten.
-pow <setting>
set power-up mode
-vol <0-4>
set beep volume. Note that this controls the modem volume for my
PCMCIA modem.
-hdd <num>
number of minutes until disk spindown
-dstretch <off|on>
enable/disable display stretch
-d <num>
number of minutes until display auto-off
-c <method>
set cooling method
-bs <setting>
set battery-save mode
-bl <off|on>
control lcd backlight
-bluetooth <off|on>
power-up + attach internal bluetooth device, or shutdown.
-fan <setting>
control fan
-video <int|ext|both|tv|mode5|mode6|mode7>
set display device for video: internal lcd, external monitor, or
tv-out
-cpu <slow|fast>
set CPU speed
-cpucache <off|on>
enable/disable CPU cache
-sleep <off|on>
enable/disable CPU sleep mode
-balarm <off|on>
enable/disable battery alarm
-palarm <off|on>
enable/disable lid-closed alarm
-walarm <dis|HH:MM[/everyday|DD/MM[/YYYY]]>
set time/date to wake
-ppower <off|on>
enable/disable annoying feature of powering-off computer when
lid is closed.
-parallel <mode>
set parallel port mode
-autooff <num>
number of minutes of idle time until system auto-off
-ostring <owner string>
set owner string. This string is displayed at boot or resume
time, if a user or supervisor password is set.
-upasswd
set or clear the user password. Toshset must be run on the
console for this to work. The password should be entered when
the prompt is displayed. If the password is currently set,
entering it will clear the password.
-spasswd
set the supervisor password. See the docs for -upasswd.
-usblegacy
USB legacy mode: enable/disable using an USB mouse as it would
be a PS/2 one, without the need to install a USB driver.
-3g power-up + attach internal 3g modem device, or shutdown.
-usbfdd
USB FDD emulation mode: is almost the same of the previous one
for a floppy. It enables the use of an USB floppy as it would be
attached to an internal FD controller (for booting etc.)
-lan Enables/disables internal LAN controller.
-soundlogo
enable/disable startup sound logo.
-startlogo
startup logo mode (picture or animation>.
-trmode
enable/disable the display’s transreflective mode.
Features may also be set by specifying the (zero-offset) index
of the option. e.g. toshset -cpu 0 sets the cpu speed to slow.
BUGS
Many features are locked and can not be changed when the battery save
mode is not ‘‘user.’’ Since I only have one laptop, I can’t test this
utility on other hardware. User feedback in this regard is helpful.
Some features do not work on my laptop and they may work on your’s, and
visa-versa.
Toshset requires an experimental version of the toshiba_acpi kernel
module with an ACPI-enabled kernel.
