------------------------------------------------------
FROM THE POLICE QUEST IV TEAM

Thank you for purchasing this game.  We hope you have
as much fun playing it as we had creating it!  We would love
to hear what you think about the game.  If you have any
comments, please write us.

------------------------------------------------------
DOS INSTALLATION

Insert disk into drive and type drive letter,
example: A: [ENTER]
At the prompt (A: or B:) type: INSTALL [ENTER]
Change options or accept default options.

------------------------------------------------------
WINDOWS INSTALLATION

To run in windows you must run the Windows install.  Start 
Windows and select "RUN" from the Program Manager.  Run 
B:\setup.  The Windows install will copy over all the files 
needed to run the game in Windows.  To run the DOS version 
you will need to run the DOS install.

------------------------------------------------------
WINDOWS SOUND

The Windows install will ask you if you want to install for 
BASE or EXTENDED level sound.  
	
BASE level sound runs on channels 13 thru 16 and is used
for sound cards like SoundBlaster, ProAudio, Adlib, or 
any FM Yamaha 3812 type card.  
EXTENDED level sound runs on channels 1 thru 10 and is 
used for cards like the LAPC-I, MT-32, SCC-1, Sound
Canvas, Turtle Beach MultiSound, or any General MIDI
device. 

------------------------------------------------------

WINDOWS MUSIC SUPPORT

If the music does not sound optimal when playing PQ4 
through Windows, you may want to consider running the 
game in DOS.  This decision will depend on what kind of
sound device you have.  If you have one of the Base
Level sound cards listed elsewhere in this README file,
you should run the game in DOS for the best possible
music.  If you have an Extended Level sound device,
then you can enjoy optimal music in Windows or in DOS.


------------------------------------------------------

MIDI SOUND MODULES WITH THE DOS VERSION

The DOS installation program for PQ4 will automatically 
default to General MIDI for Music if you have an MPU-401
adapter card in your system.  This is fine as long as
you really have a General MIDI device.  However, if your 
sound module is not General MIDI compatible, the music 
will not sound right.  

If you have a Roland MT-32, LAPC-1, CM-32, or CM-64, you 
should choose the MT-32 Music option.

Roland Sound Canvas, Roland SCC-1, Roland RAP-10,  
Yamaha T3 or any other compatible General MIDI device
owners should be fine with the default General MIDI 
option.

------------------------------------------------------

SOUNDBLASTER / THUNDERBOARD INTERRUPT SETTING

Each time you start the game, it scans your hardware to 
determine the proper interrupt configuration for your sound 
card.  Depending on your system configuration, and the other 
devices installed, this process may not always be 
successful.  The result is distorted or missing digital 
audio sounds, very slow game speed, or game lockups.  This 
is most likely to happen when using a mouse connected via a 
bus interface.

If you experience any of these symptoms, you can explicitly 
set the sound card interrupt using the BLASTER environment 
variable.  The SoundBlaster and Thunderboard drivers will 
first look for the interrupt setting in the BLASTER 
environment variable, and only attempt the autodetection if 
it is not found.

The BLASTER environment variable is usually defined via a 
SET command in your AUTOEXEC.BAT file.  It should look 
something like this:

                 SET BLASTER=A220 D1 I7

This specifies the I/O address, DMA channel, and interrupt 
line for your sound card, and is used by many products to 
determine this information.

You can determine the setting of all your environment 
variables by typing SET at the DOS prompt.  You can display 
the current value of the BLASTER variable by typing ECHO 
BLASTER at the DOS prompt.

If you already have a BLASTER environment variable set, make 
sure the values correspond to the actual hardware 
configuration of the card.  Refer to the card's reference 
documentation for more information.

If you do not currently have a BLASTER environment variable, 
you should set one according to your sound card's 
configuration.  The only value required by Sierra games is 
the interrupt line.  If your sound card is configured for 
interrupt 7, the following command will insure that this 
game will properly determine your sound card configuration 
at startup:

               SET BLASTER=I7

This command can be added to an AUTOEXEC.BAT file on a boot
disk, so it will run each time your computer is started
with the boot disk in the A: drive.  Refer to your 
computer's documentation for more information on the SET 
command, environment variables, and the AUTOEXEC.BAT file.  
For additional technical information regarding boot disk 
usage, please refer to your Sierra Game Manual.

------------------------------------------------------

RUN THE GAME

For DOS:

   From the directory in which you have installed
   Police Quest IV, type: PQ4 [ENTER]

For Windows:

   Double click on the icon for PQ4.

------------------------------------------------------

TIPS FOR FASTER LOADING

If you notice the game or opening cartoon running slowly, it 
may be due to a fragmented hard drive.  There are many 
commercial and shareware hard drive unfragmenting 
programs available.

-----------------------------------------------------

PRO AUDIO USERS

If you are using a Pro AudioSpectrum 16 or Plus card and 
experience problems during the game, rerun the INSTALL 
utility and select "Sound Blaster" as your audio device.

Selecting "Sound Blaster" will utilize the PAS card's built-in 
Sound Blaster emulation for digitized audio effects.

-----------------------------------------------------

SIERRA ON-LINE MANUAL BOOT DISK INSTRUCTIONS

The following instructions can be used if the automatic boot disk maker 
included in the install program does not function properly on your system.
If you have the CD-ROM version of this program, or you are using certain 
hard drive compression utilities, you will need to add any necessary
driver lines to your config.sys and autoexec.bat files.  

FORMATTING THE DISK

PLEASE NOTE: It is necessary to format the disk even if the disk is already 
formatted.  The /S switch will transfer files to the boot disk which are 
necessary for the disk to work correctly.

To make a  CD-ROM Boot Disk, format a high density diskette in the A: drive.  
(Use /F:360 or  /F:720 parameter if using a low density diskette) Note: This 
will not work in the B: drive.  Type the command as follows:  

	FORMAT  A:/S  

If after entering this command the system responds with a "Bad command or
file name" error, then type:

	PATH=C:\DOS  

Now retype the FORMAT command above.  If you still receive the same error,
the MS DOS FORMAT command may not be on your system or it may have been 
renamed.  Programs such as PC Tools and Norton Disk Utilities can rename 
the format command to prevent accidental loss of data. 


LOCATING THE MOUSE DRIVERS

If you plan to use a mouse with your game, it will be necessary to first 
load the mouse driver.  To do this, locate the mouse driver and copy it to 
the boot disk in your A: drive.  There are two types of mouse drivers 
available, MOUSE.SYS, which must be loaded in the CONFIG.SYS file and 
MOUSE.COM which must be loaded in the AUTOEXEC.BAT file.  You do not need 
to load both MOUSE.SYS and MOUSE.COM.  Locate the MOUSE.SYS or MOUSE.COM 
file.  Because the file MOUSE.SYS is usually smaller than MOUSE.COM we 
recommend that the MOUSE.SYS file be used in order to free more memory.

a) Locating the mouse drivers:
If you do not know where the MOUSE.SYS or MOUSE.COM files are located on 
your system, and you have MS-DOS 5.0 or above, the command below should help 
in locating your mouse drivers.  Type the following at the C:\> prompt.

	DIR  \MOUSE  /S  

This command only works with MS-DOS 5.0 or above and will cause the system 
to search all sub directories for a file called mouse.  If the system locates
a file called mouse, it will display the path where the mouse files are 
located.  For instance, if the MOUSE.SYS file is located in a C:\MOUSE> 
directory, the system will display:


Directory of C:\MOUSE
	MOUSE    SYS     55160 03-10-92   3:10a
	MOUSE    COM     56408 03-10-93   6:00a

If the system does not locate a mouse, your driver may have a different name 
or these files may not be currently installed on the system.  Some other 
common names for mouse drivers are IMOUSE, GMOUSE, and HPMOUSE.  Your mouse 
drivers may have been included on a floppy disk which came packaged along 
with your mouse.  For information on the proper name for your mouse, check the 
owner's manual which came with your mouse.  

b) Copying the mouse driver:
Once you have located the mouse driver, you will need to copy it to the boot 
disk.  In this step, we will assume that the mouse drivers were located in 
the C:\MOUSE> directory as shown in the step above.  To copy the MOUSE.SYS 
file to the boot disk, type the following at the C:\> prompt:

	COPY  C:\MOUSE\MOUSE.*  A:  

Please substitute the appropriate path and file name for your mouse driver in 
the command line above.  You should then see a message indicating some files 
were copied.


CREATING THE CONFIG.SYS FILE

Now switch to the A: and type the following:

	COPY  CON  CONFIG.SYS  (The cursor will drop down one line and 
blink)
	FILES=50  
	BUFFERS=30 

If you are using the MOUSE.SYS file to load your mouse, add the following 
line to the CONFIG.SYS.

	DEVICE=MOUSE.SYS  

Complete the file by pressing the  F6  Function key 



CREATING THE AUTOEXEC.BAT FILE

Now create an AUTOEXEC.BAT file on the A: drive by typing:

	COPY  CON  AUTOEXEC.BAT    (the cursor will drop down one line)
	SET  COMSPEC=C:\COMMAND.COM  
	PROMPT  $P$G  
	PATH=C:\DOS  

If you are using the MOUSE.COM file to load the mouse, add the following 
line to the AUTOEXEC.BAT file.

	MOUSE.COM  

Complete the file by pressing the  F6  Function key 

Now you are ready to use your new Sierra Boot Disk.  Place the boot disk in 
your A: drive and press the   and  keys at the same time.  
Your computer will reboot and you will be ready to start your Sierra game 
as you normally would.
