                        Welcome to 
                   "Island of Dr Brain"

Thank you for purchasing this game.  We hope you have
as much fun playing it as we had creating it!

Installation Instructions:
Place the CD in your CD-ROM drive and change to the prompt for that drive.
Type INSTALL <Enter>, follow the prompts to configure the game for
your computer.

This file contains the absolutely latest and greatest
information about this version of the game.  Right now,
we know about the following "special situations":

1. ALL NEW!  After the logo displays at the beginning of
   the game, a new on-line menu will appear.  All last-
   minute updates are found under the heading "INFORMATION".

2. If you have any problems starting up the game, the information
   given at the end of this file should help you solve your problem.

3. If you have a ProAudio Spectrum and music is not playing or
   skipping in your game, try running from a bootable disk,
   which can be made with the install program.

4. If your computer is close to the minimum "free memory"
   to run this game, you may experience slowdowns in some
   areas or receive the error message "Out of Hunk".  If
   this occurs, try running the game from a boot disk .  
   (To check free memory, type "chkdsk" from DOS.  If the 
   "bytes free" number reported is less than 580,000, you 
   may need to use a boot disk.)

5. Sometimes INSTALL will report that you have the Disney DAC.
   If you don't have it, just don't choose it!

6. Sometimes INSTALL will report that you have a joystick when
   you don't have it.  Be sure that you don't have joystick
   selected if you don't have it.

7. If you have a Tandy 2500XL and experience problems while 
   installed for "Tandy with DAC", run the install program
   again and select "No Audio/Voice Card". 

8. When you install the game to a directory other than the 
   default directory of "BRAIN2", you will need to edit the
   BRAIN2.BAT file one directory up from your game directory.
   If you install the game to a directory called "ISLAND", 
   edit the batch file to say "CD ISLAND" rather than 
   "CD BRAIN2".

IMPORTANT NOTE: Please read the entire instructions prior to starting
at Step 1.  You can skip Steps 3 and 4 if you are not playing a CD game.


STEP 1
FORMATTING THE DISK
To make a boot disk, format a high density diskette in the A: drive.
(It is necessary to reformat the disk if it is already formatted.)
Formatting the disk with the /S switch will transfer the "system files"
to the disk and allow the computer to boot up correctly.  The disk must
be in the A: drive; the computer will not boot from the B: drive.  Type
the FORMAT command as follows:

FORMAT A: /S <ENTER>

If you get a "Bad command or file name" error message, type: 

PATH=C:\DOS <ENTER>

Then retype the FORMAT command above.  If you receive the error again,
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
sometimes rename the FORMAT command to prevent accidental loss of data.
If you are using a program of this type, check your documentation to
find out how to format a SYSTEM DISK, then proceed to Step 2.

STEP 2
LOCATING THE MOUSE DRIVER
If you are playing a game that uses a mouse, the Microsoft compatible
mouse driver must be loaded into memory with the boot disk. There are
two kinds of mouse drivers available: those that load in the CONFIG.SYS
file and those that load in the AUTOEXEC.BAT file.  CONFIG.SYS mouse
drivers have an extension of .SYS (MOUSE.SYS) and AUTOEXEC.BAT drivers
have either a .COM or .EXE extension (MOUSE.COM, MOUSE.EXE).  You must
load at least one of these drivers, but it is not necessary to load
them all.

If you do not know where the mouse drivers are located on your system,
the command below should help you locate them.  Type the following at
the C:\ prompt:

DIR MOUSE* /S <ENTER>

This command will cause the system to search all subdirectories for a
file called MOUSE.  If the system locates a MOUSE file, it will display
the path where the file is located.  For example, if the MOUSE.COM 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	03-10-03	6:00a

If this procedure does not locate a MOUSE file, your mouse driver may
have a different name. Some common names for mouse drivers are IMOUSE,
GMOUSE and HPMOUSE.  Your should check your mouse documentation for
the exact file names and how to install them.

Once you have located the mouse driver, you must copy it to the boot
disk.  The following example assumes that the mouse drivers are located
in the C:\MOUSE directory as shown in the step above.  To copy the
MOUSE files to the boot disk, type:

COPY C:\MOUSE\MOUSE.* A: <ENTER>

Substitute the appropriate path and file names for your mouse drivers
in the command above.  After you press ENTER, you should see a message
indicating that some files were copied.


STEP 3
LOCATING THE CD ROM DEVICE DRIVER (skip if not playing a CD game)
The CD ROM drive requires a device driver loaded in the CONFIG.SYS file.
This driver must be loaded correctly or you will be unable to access
your CD ROM drive. To make sure that the device driver loads correctly
on the boot disk, look at the CONFIG.SYS on the hard drive and copy the
driver line from there.  At the C:\ prompt, type:

TYPE CONFIG.SYS|MORE

NOTE:	  The | is called a "pipe" command and is created by pressing
<SHIFT> <BACKSLASH>.

The CONFIG.SYS file will display on the screen.  Look for the line that
loads the CD ROM device driver.  This line will contain the same "/D:"
switch as the MSCDEX line in the AUTOEXEC.BAT file.  Using the MSCDEX
example above,

Step 3 continued...
you would be looking for a line containing "/D:MSCD001".  The line
should look something like this:

DEVICE=C:\DRV\CDROMDRV.SYS /D:MSCD001 /P:220
DEVICEHIGH=C:\DRV\CDROMDRV.SYS /D:MSCD001 /P:220
DEVICEHIGH /L:14652 =C:\DRV\CDROMDRV.SYS /D:MSCD001 /P:220

The device driver in your CONFIG.SYS may differ slightly from those
listed above.  Carefully write down the line for use in your boot disk.
Leave out the "/L:" information, if any.  Your CD ROM device line
should appear as follows:

DEVICEHIGH=C:\DRV\CDROMDRV.SYS /D:MSCD001 /P:220

NOTE:  If you have a SCSI CD ROM drive, there may be an additional
driver in your CONFIG.SYS that must be loaded for the CD ROM device
drivers to load correctly.  Check your CD drive documentation for
more information.


STEP 4
LOCATING THE MSCDEX CD ROM EXTENSION (skip if not playing a CD game)
In addition to the CD ROM device driver in the CONFIG.SYS, your CD
ROM drive requires MSCDEX, the Microsoft extension for CD ROM drives.
If this extension is not loaded correctly in the AUTOEXEC.BAT, you will
be unable to access your CD ROM drive.  To make sure that MSCDEX loads
correctly on the boot disk, look at the AUTOEXEC.BAT on the hard drive
and copy the MSCDEX line from there.  At the C:\ prompt, type:

TYPE AUTOEXEC.BAT|MORE <ENTER>

The AUTOEXEC.BAT file will display on the screen.  Look for the line
that loads the MSCDEX extension.  It should look something like this:

C:\DOS\MSCDEX /D:MSCD001
LH C:\DOS\MSCDEX /D:MSCD001 
LOADHIGH /L:14429 C:\DOS\MSCDEX /D:MSCD001

The MSCDEX line in your AUTOEXEC.BAT may differ slightly from the ones
above. Carefully write down the line for use in your boot disk.  Leave
out the "/L:" information, if any. If the "LH" is missing, add it.
For example, any of the above lines will appear on your boot disk as
follows:

LH C:\DOS\MSCDEX /D:MSCD001


STEP 5
LOCATING THE SOUND CARD DRIVERS
Many sound cards have drivers or initialization lines that must be
loaded in the AUTOEXEC.BAT or CONFIG.SYS.   Some sound cards that
require these drivers or initialization routines are the SoundBlaster
16, MAD16 and the Aria 16.

At the end of these Boot Disk Instructions, you will find a section
labeled "Sound Cards".  These tables contain the sound card lines
for many common sound cards.  Check to see if your sound card is on
the list.  If it is, then you will need to add the appropriate lines
to the AUTOEXEC.BAT and/or CONFIG.SYS on your boot disk.  If your
sound card is not on the list, you should check your documentation
for information on what needs to load in the AUTOEXEC.BAT and
CONFIG.SYS.


STEP 6
CREATING THE CONFIG.SYS FILE
To create the CONFIG.SYS file on the boot disk, switch to the A: drive
and type the following:

COPY CON CONFIG.SYS <ENTER>  (the cursor will drop down one line and
blink)
DEVICE=C:\DOS\HIMEM.SYS <ENTER>
DEVICE=C:\DOS\EMM386.EXE NOEMS <ENTER>
DOS=HIGH,UMB <ENTER>
FILES=30 <ENTER>
BUFFERS=20 <ENTER>

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

DEVICEHIGH=A:\MOUSE.SYS <ENTER>

If you're playing a CD game, add the CD ROM device driver as you
wrote it down in the "Locating the CD ROM Device Driver" section.
For example:

DEVICEHIGH=C:\DRV\CDROMDRV.SYS /D:MSCD001 /P:220  <ENTER>

If you need to load any sound card drivers, copy them from the "Sound
Cards" section now.  The following example lines are for the
SoundBlaster 16:

DEVICEHIGH=C:\SB16\DRV\CTSB16.SYS /UNIT=0 /BLASTER=A:220 I:5 D:1 H:5 <ENTER>
DEVICEHIGH=C:\SB16\DRV\CTMM.SYS <ENTER>

Complete the file by pressing <F6> <ENTER>.


STEP 7
CREATING THE AUTOEXEC.BAT FILE
To create the AUTOEXEC.BAT file on the boot disk, switch to the A:
drive and type the following:

COPY CON AUTOEXEC.BAT <ENTER>  (the cursor will drop down one line
and blink)
@ECHO OFF <ENTER>
C:\ <ENTER>
SET COMSPEC=C:\COMMAND.COM <ENTER>
PROMPT SIERRA BOOT DISK $_$P$G <ENTER>
PATH=C:\;C:\DOS;C:\SIERRA <ENTER>

If you are using the MOUSE.COM or MOUSE.EXE file to load your mouse
driver, add the appropriate line:

LH A:\MOUSE.EXE <ENTER>

If you're playing a CD game, add the MSCDEX line as you write it down
in the "Locating the MSCDEX CD ROM Extension" section.  For example:

LH C:\DOS\MSCDEX /D:MSCD001 <ENTER>


Step 7 continued...
If you need to run any sound card initialization programs or load any
drivers, copy them from the "Sound Cards" section now.  The following
example lines are for the SoundBlaster 16:

SET BLASTER=A220 I5 D1 H5 T6 <ENTER>
SET SOUND=C:\SB16 <ENTER>
SET MIDI=SYNTH:1 MAP:E <ENTER>
C:\SB16\SB16SET /M:220 /VOC:220 /CD:220 /MIDI:220 /LINE:220 <ENTER>
C:\SB16\DIAGNOSE /S <ENTER>

Complete the file by pressing <F6> <ENTER>.


STEP 8
REBOOT THE SYSTEM AND START THE GAME
Reboot your system by pressing the <RESET> button on your computer or
by using the <CTRL> <ALT> <DELETE> key sequence on your keyboard.
Refer to your game documentation for the steps to start the game.
