NAME

       thinkpad - device driver modules for IBM ThinkPad laptops

SYNOPSIS

       insmod     thinkpad     [enable_smapi=     n]    [enable_superio=    n]
       [enable_rtcmosram= n] [enable_thinkpadpm= n]
       insmod smapi
       insmod superio
       insmod rtcmosram
       insmod thinkpadpm

DESCRIPTION

       thinkpad, smapi, superio, rtcmosram and thinkpadpm are  device  drivers
       for certain ThinkPad components in the form of loadable kernel modules.

       The thinkpad driver merely loads the other driver  modules  as  needed.
       It also provides access to the other drivers on non-devfs systems.  The
       smapi driver is the interface to the IBM System Management  Application
       Program  Interface  (SMAPI)  BIOS found in some ThinkPads.  The superio
       driver controls the Super I/O  chip.   The  rtcmosram  driver  provides
       access  to  the  RT/CMOS  nonvolatile RAM.  The thinkpadpm driver makes
       available certain power management functions.

       Each module adds an entry under /proc/driver/thinkpad named like itself
       which contains some information about itself.

PARAMETERS

       The thinkpad module takes the following parameters.

       enable_smapi=n
              Disable (0) or enable (1) use of the smapi module

       enable_superio=n
              Disable (0) or enable (1) use of the superio module

       enable_rtcmosram=n
              Disable (0) or enable (1) use of the rtcmosram module

       enable_thinkpadpm=n
              Disable (0) or enable (1) use of the thinkpadpm module

SECURITY

       The  user  requires  write  permission  on  the device file in order to
       change settings or to "sedate" the machine.

FILES

       /proc/driver/thinkpad
              Files containing information  about  the  drivers  are  in  this
              directory.

       /dev/thinkpad
              This  is  a  directory  containing  the following special device
              files:

       /dev/thinkpad/thinkpad
              Special device file (char, major 10, minor  170)  through  which
              ThinkPad devices are controlled

       /dev/thinkpad/smapi
              Special device file through which the SMAPI BIOS may be accessed

       /dev/thinkpad/superio
              Special device file through which the  Super  I/O  chip  may  be
              controlled

       /dev/thinkpad/rtcmosram
              Special  device  file  through which the RT CMOS RAM chip may be
              controlled

       /dev/thinkpad/thinkpadpm
              Special  device  file  through  which  certain  ThinkPad   power
              management actions may be performed

BUGS

       None known.
