1.0 PREREQUISITE SUPPORT
------------------------

In order to install the Enhanced Intel SpeedStep(R) technology support
for OS/2 you must first install the Advanced Power Management (APM)
feature on your OS/2 system.  If you do not already have the Advanced
Power Management feature installed on your system, you can install it
through the OS/2 Selective Install process.

Latest OS2 Loader package from DDPAK should be applied on your system 
prior installing the Enhanced Speedstep support package


2.0  INSTALLATION INSTRUCTIONS
------------------------------

The OS2SPDST.EXE file that you received contains the following
files in a self-extracting format:

    - GSVINST.EXE     Executable that installs your SpeedStep
                        support
    - APM.SYS         SpeedStep device driver
    - README.TXT      This file that you are reading
    - WPCONFIG.DLL    WorkPlace Shell functional DLL

In addition, there are language-specific subdirectories that
contain the following files:

    - GSVDAEMN.EXE  SpeedStep Daemon executable that performs
                      CPU state changes.
    - WPCONMRI.DLL  WorkPlace Shell informational DLL
    - WPGSVPWR.HLP  SpeedStep Help Library

This installation package supports all languages supported for
OS/2 Warp 4.0.

To use these OS/2 SpeedStep driver files, you must expand the
OS2SPDST.EXE file into its component files by:

  (a.) opening an OS/2 command prompt (window or full screen, full screen 
       recommended) on your computer,

  (b.) type "OS2SPDST.EXE -d" at the command prompt.

Once the OS2SPDST.EXE file is expanded, continue with the
installation instructions.


1.  Open an OS/2 full screen command prompt on your computer.


2.  Change your directory to the directory containing the
    SpeedStep files that were just expanded.  As an example, type A:  
    if you are installing the driver from the A: drive diskette.


3.  At the OS/2 command prompt, type GSVINST.  
    This command will:
      (a.) Verify that the OS/2 version on the boot partition is
            at one of the following levels:
                Convenience Pack 1, with FixPak C1-2 or C1-3
                Convenience Pack 2, with no FixPak or FixPak C2-1
                Convenience Pack 2 Refresh, with no FixPak
            If this is not the case, then this installation will stop.

      (b.) Save the existing Advanced Power Management driver as
           APM.SAV in the OS2\BOOT directory on the boot
           partition.

      (c.) Add the new APM.SYS device driver in the OS2\BOOT
           directory on the boot partition.

      (d.) Save the existing SpeedStep daemon as GSVDAEMN.SAV in
           the OS2\BOOT directory on the boot partition.

      (e.) Add the new language specific GSVDAEMN.EXE SpeedStep
           daemon in the OS2\BOOT directory on the boot partition.

      (f.) Save the existing WorkPlace Shell DLLs as
                      WPCONFIG.SAV
                      WPCONMRI.SAV
           in the OS2\DLL directory on the boot partition.

      (g.) Add the associated language specific WorkPlace Shell
           DLL (WPCONMRI.DLL) to the OS2\DLL directory on the boot
           partition.

      (h.) Add the associated language independent WorkPlace Shell
           DLL (WPCONFIG.DLL) to the OS2\DLL directory on the boot
           partition.

      (i.) Save the existing SpeedStep Help Library (if any) as
                      WPGSVPWR.SAV
           in the OS2\HELP directory on the boot partition.

      (j.) Add the associated language specific SpeedStep Help
           Library to the OS2\HELP directory on the boot

      (k.) Initialize the .INI file to contain default values for
           the SpeedStep fields.


4.  This completes the installation procedure.  You should examine
    the install log (GSVINST.LOG) to verify that the installation
    was successful. After Installation your computer must be rebooted 
    to allow the new settings and device driver(s) to take effect.

3.0  UNINSTALL INSTRUCTIONS
---------------------------

The GSVINST.EXE program creates a log file called GSVINST.LOG.
This log file contains information about which files have been
changed and where the original files have been backed up.
Uninstallation of this package, if required, must be done manually by
examining the GSVINST.LOG file and copying the backup files one
by one to the original location.

You can open an OS/2 command prompt window or fullscreen,
change the current drive to be the target partition and do the 
following commands:

COPY   \OS2\BOOT\APM.SAV        \OS2\BOOT\APM.SYS
COPY   \OS2\DLL\WPCONFIG.SAV    \OS2\DLL\WPCONFIG.DLL
COPY   \OS2\DLL\WPCONMRI.SAV    \OS2\DLL\WPCONMRI.DLL
COPY   \OS2\HELP\WPGSVPWR.SAV   \OS2\HELP\WPGSVPWR.HLP
COPY   \OS2\BOOT\GSVDAEMN.SAV   \OS2\BOOT\GSVDAEMN.EXE

If there are any error messages as a result of these commands,
it could be because the original file was not there before the install.
You should check the GSVINST.LOG file to verify whether that was the reason.

The GSVINST.EXE backup method does not consider multiple successive
installations.  If you intend to be able to simply uninstall this package
after multiple successive installations, then you will need to do an
uninstall in between each pair of installs, or revise this uninstall
method to create your own more comprehensive uninstall method.


4.0 HARDWARE CONSIDERATIONS
---------------------------

This driver can be installed on a computer which does not have
the Intel SpeedStep(R) technology, or Enhanced Intel SpeedStep(R)
technology, and it will not have any effect on the computer's processor
mode.



5.0 OPERATING PARAMETERS
------------------------------------------------------

Intel(R) has introduced dual-mode mobile processor technologies, known
as Intel SpeedStep(R) technology and Enhanced Intel SpeedStep(R)
technology, that lets a mobile computer to operate at a higher
frequency (that is, "Maximum Performance") when plugged into a wall
outlet and automatically switch to a lower power and frequency (that is,
"Battery Optimized Performance") when running on battery, conserving
battery life.

A settings page named "Performance" has been added to the
WorkPlace Power object.  You can view the current SpeedStep
performance mode by selecting the Power icon in your System Setup
folder and pressing the left mouse button to display the "Power -
Full status" panel.  You can access the SpeedStep Technology
Properties by selecting the icon in the upper left hand corner of
the "Power - Full status" panel, depressing the right mouse
button, and then selecting Properties from the pop-up menu.  The
SpeedStep Technology Properties are on the "Performance" page.

Checking the "Disable Power and Performance Optimization control" box
disables the Enhanced Intel SpeedStep(R) technology support for OS/2.
In certain cases, unchecking this box will not immediately re-enable
the Enhanced Intel SpeedStep(R) technology support for OS/2. In these
cases, to re-enable the SpeedStep Technology Device Driver for OS/2,
after unchecking this box, you must shutdown OS/2, enter the BIOS
Setup, and re-enable the SpeedStep Technology in the BIOS, and then
reboot OS/2.

Checking the "Automatically change performance when the power
source changes" box causes the SpeedStep Technology daemon
for OS/2 to change processor modes when the power source changes
from batteries to a wall outlet or from a wall outlet to
batteries.  The processor mode used as the new state depends on
the selection made from the applicable pull-down menu (as
described below).

If the "Automatically change performance when the power source
changes" box is checked, then checking the "Ask me before
automatically changing performance" box causes the SpeedStep
Technology daemon for OS/2 to request confirmation before changing
processor modes when the power source changes from batteries to a
wall outlet or from a wall outlet to batteries.

If the "Automatically change performance when the power source
changes" box is checked, then checking the "Disable audio
notification when performance changes." box causes the SpeedStep
Technology daemon for OS/2 not to issue its audible notification
when the processor mode changes automatically due to a change in
the power source.

You can select the SpeedStep processor mode for use when the
computer is powered by batteries from the "Running on Batteries"
pull-down menu. This mode is used when the computer is restarted
while powered by batteries.  In addition, if the "Automatically
change performance when the power source changes" box is checked,
the mode selected is used whenever the power source for the
computer changes from wall outlet to batteries.

You can select the SpeedStep mode to use when the computer is
powered from a wall outlet from the "Plugged in" pull-down menu.
This mode is used when the computer is restarted while powered
from a wall outlet.  In addition, if the "Automatically change
performance when the power source changes" box is checked, the
mode selected is used whenever the power source for the computer
changes from batteries to a wall outlet.
