1. TACTICAL OPERATIONS ABORTS INSTALLATION:

If  the Tactical Operations installation drops you out to the 
DOS prompt prematurely, try typing the following at the DOS 
prompt to remove a possible conflict with the auto-detection 
function: 
    INSTALL -A 
If the problem persists, contact Origin Product Support.


2. FULL INSTALLATION VERSUS PARTIAL INSTALLATION

To prevent possible redundant map generation during 
playthroughs, we recommend that you choose the same type of 
installation for Tactical Operations as you did for Strike 
Commander.  For example, full installation users of Strike 
Commander should select full installation for Tactical 
Operations.


3. INSTALLING STRIKE COMMANDER: SPEECH ACCESSORY PACK AFTER 
INSTALLING TACTICAL OPERATIONS:

If you are going to install the Strike Commander: Speech 
Accessory Pack after installing Tactical Operations then you 
will need to edit the SCTO1.CFG file as follows:

a. At the 'C:\' prompt, type:
     EDIT C:\SC\SCTO1.CFG  
b. When the new screen appears, make the following changes:
    =objects.tre
    =textures.tre
    =misc.tre
    =scto1.tre
    =sound.tre
    =gameflow.tre
    =msspeech.tre
    =mgspeech.tre
These line will be followed by two other sound configuration 
lines.  Do not alter their information.
c. When you are finished, type the following keys:
    <ALT>, <F>, <X>, and <Y>

This will allow you to have speech during Tactical Ops only if 
you have speech pack installed to the same directory.   If you 
are installing Tactical Ops after Strike Commander AND the 
Speech Accessory Pack, then you will not have to do this.


4. NEW FEATURES TO STRIKE COMMANDER

Realistic Flight, Rudder Pedals, Digital Effects, and General 
Midi are new features in Tactical Operations.  Installing 
Tactical Ops also adds these features to the regular Strike 
Commander missions.  


5. REALISTIC FLIGHT AND RUDDER PEDAL SUPPORT

Realistic Flight and Rudder Pedals can only be turned on at the 
OPTIONS menu while in flight.  To reach the Options Menu while 
flying, press <ALT> <O>.  Then press the FLIGHT button.  You can 
now turn on the REALISTIC FLIGHT and RUDDER PEDALS by pressing 
their buttons.


6. DIGITAL EFFECTS

To turn on the Digital Effects feature, press <ALT> <O> while in 
flight.  Press the AUDIO button and make sure that the DIGITAL 
FX button is pressed down (darkened).


7. GENERAL MIDI MUSIC

To utilize the General MIDI music features, you will have to 
change your hardware configuration.  Type "INSTALL" at the 
Strike Commander directory (default: C:\SC) after installing 
Tactical Operations.

Strike Commander and Tactical Operations has joined the next 
generation of sound quality with its support of the General MIDI 
standard as defined by the MPU-401 instruction set.  At the time 
of publishing, only a few cards support MPU-401.  These cards 
include the Roland SCC-1, Roland RAP-10, Creative Labs Sound 
Blaster 16 with the attached Waveblaster daughterboard, and the 
Creative Labs Sound Blaster ASP 16 with the attached Waveblaster 
daughterboard.  Other manufacturers have already or are planning 
to release sound cards that utilize the MPU-401 instruction set.  
However, sound cards that use a memory-resident program (TSR) to 
emulate MPU-401 MAY NOT work with this software.  

NOTE: Some General MIDI sound cards offer digitized speech or 
sound effect capabilities.  However, this product may not 
support the digitized sound or speech capabilities of these 
cards.  As in the case of the Roland RAP-10, customers will need 
to use a second sound card such as a Sound Blaster, Sound 
Blaster Pro or 100 percent compatible sound card for digitized speech 
and effects.  Review your sound card documentation or contact 
the manufacturer if you have any questions.  


8. SB16/WAVEBLASTER & CH FLIGHTSTICK COMBINATION

Due to a hardware conflict between the joystick port on the 
Creative Labs' SB16/Waveblaster combination and the CH 
Flightstick, General MIDI music will not be heard when the 
Flightstick is connected to the SB16/Waveblaster joystick port.  
Another manufacturer's joystick or another joystick port must be 
used to receive the General MIDI music.  Contact the respective 
manufacturers if you have any further compatibility questions.


9. DIGITAL EFFECTS VERSUS OLD SOUND EFFECTS

With DIGITAL FX turned on, you may run into instances where you 
will get the old sound effects.  This will happen if a digital 
effect is supposed to be played at the same time as another 
digital effect.  The chip used by most sound cards to produce 
digitized sound and effects can only play one digitized effect 
at a time. 


10. ERROR CODES #1910 AND #1941

If you try to start a new game and it crashes to DOS with an 
'Error #1910' or 'Error #1941, this is caused by a bad 
installation or a corrupted file on the original installation.  
To determine which case, boot to a clean configuration that does 
not load other conflicting device drivers such as a disk cache.  
See your Strike Commander Install Guide for more information on 
the proper configuration.  Next, delete all files from the 
Strike Commander directory (default: C:\SC).  Finally, reinstall 
Strike Commander and Tactical Operations.  


11. JOYSTICK CALIBRATION PROBLEMS

In the event that you experience any joystick calibration 
problems, be sure that you have only one gameport open for your 
joystick.  This includes gameports present on sound cards, 
gamecards or I/O cards.  If you are using a multi-speed 
gamecards, be sure that you have performed the software or speed 
dials tests for your particular gamecard.  If you continue to 
have problems, try adjusting the speeddial or numeric software 
settings a little higher than normal.  If the problem persists, 
you may have a defective joystick or gameport.  


12. MS-DOS VERSION 6.0 & DOUBLESPACE

Note: Strike Commander has been fully tested with Double Space 
disk compression utility that shipped with MS-DOS version 6.0.  
We cannot guarantee the compatibility of our games with other 
disk compression utilities.

Due to the large conventional memory requirements of Strike 
Commander and DoubleSpace, we highly recommended that you use 
the instructions within your Strike Commander Install Guide to 
make a boot disk.  Use the following configuration for your 
CONFIG.SYS and AUTOEXEC.BAT files.

    config.sys
    DEVICE=C:\DOS\HIMEM.SYS
    DEVICE=C:\DOS\EMM386.EXE 2592 /I=B000-B7FF RAM
    DOS=UMB
    DOS=HIGH
    FILES=25
    BUFFERS=25
    SHELL=C:\DOS\COMMAND.COM /P
    DEVICEHIGH=C:\DOS\DBLSPACE.SYS /MOVE

    autoexec.bat
    PROMPT $P$G
    PATH=C:\DOS
    C:
    CD SC 
    SC   (or use SCTO1 if you wish to use the disk for 
Tactical Ops)

Now insert this disk into your A: drive and reboot your 
computer.  This disk should automatically take you into the game 
with plenty of memory.


13. INTERNAL STACK OVERFLOW

This error will typically occur if SB16/Waveblaster owners 
select 'GENERAL MIDI' instead of 'WAVEBLASTER' as their music 
card during the sound configuration of the installation program.  
Simply type 'INSTALL' from the Strike Commander directory 
(default: C:\SC).  Select 'WAVEBLASTER' when prompted for your 
type of music card.


14. STRIKE COMMANDER DISK #8 HANGS/TERRAIN MAPS DO NOT GENERATE

On some computers such as the IBM Valuepoint and a number of 
Packard Bells, the Strike Commander installation map try to use 
a region of upper memory that is already occupied.  This will 
cause Disk #8 to hang up as it approaches the Terrain Map 
Generation.  To remedy this, we recommend that you create a boot 
disk using the instructions within the Strike Commander Install 
Guide.  Use the following configuration for your CONFIG.SYS 
file:

    config.sys
    DEVICE=C:\DOS\HIMEM.SYS
    DEVICE=C:\DOS\EMM386.EXE 2592 /X=E000-EFFF RAM
    DOS=HIGH
    FILES=25
    BUFFERS=25
    SHELL=C:\DOS\COMMAND.COM /P  

Insert the new boot into your A: drive and reboot your computer.  
Now begin the installation again beginning with Disk #1 and the 
terrain maps should be generating at the end of Disk #8.  
Partial Install users will only see one map generated before the 
installation ends.  If the problem persists, contact Origin 
Product Support.
