Sierra On-Line's Technical Support department prepared the following
instructions as an added service to our customers.  PLEASE NOTE:
NEITHER SIERRA NOR DYNAMIX MAKE ANY CLAIMS, GUARANTEES, AND/OR
PROMISES THAT THE FOLLOWING INSTRUCTIONS WILL WORK ON ANY AND/OR ALL
COMPUTER SYSTEMS.

Many people with CD-ROM drives are having trouble finding enough free
memory to run Sierra's CD-ROM games.  A CD-ROM Boot disk is the most
elegant, temporary way to create a simplified and optimal environment
in which to run Sierra CD-ROM games. These instructions are only for
386 or 486 computers using DOS 5.0.

Print out or type to the screen the current CONFIG.SYS and
AUTOEXEC.BAT files and note the current CD-ROM driver commands.  Note
any variations from the directions below.

To make a DOS 5.0 CD-ROM Boot Disk, format a High Density diskette in
the A: drive. (Use DOS 5.0's /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

Now switch to the A: and type the following:
 COPY CON CONFIG.SYS <ENTER> (the cursor will drop down one line and blink)
 DEVICE=C:\DOS\HIMEM.SYS
 DEVICE=C:\DOS\EMM386.EXE RAM
 FILES=30
 BUFFERS=30
 STACKS=0,0
 BREAK=ON
 DOS=HIGH,UMB
 LASTDRIVE=Z
 DEVICEHIGH=C:\DOS\SETVER.EXE
__________________________________

The Pro AudioSpectrum requires the following lines:
 DEVICEHIGH=C:\PROAUDIO\TSLCDR.SYS /D:MVCD001 /R /S:31
 DEVICEHIGH=C:\PROAUDIO\MVSOUND.SYS D:1 Q:7
__________________________________

The SoundBlaster Pro uses this line:
 DEVICEHIGH=C:\SBPRO\DRV\SBPCD.SYS /D:MSCD001 /P:220
__________________________________

NEC CD-ROM drives require this line:
 DEVICEHIGH=C:\SCSI\NECCDR.SYS /D:NECCD
__________________________________

The Sony Laser Library requires this line:
 DEVICEHIGH=C:\LASERLIB\SONY_CDU.SYS /D:SONY_001 /B:340 /Q:* /T:* /M:H

Complete the file by pressing the  F6  function key <ENTER>

Now create an AUTOEXEC.BAT file by typing:

 COPY CON AUTOEXEC.BAT <ENTER> (the cursor will drop down one line)
 PROMPT $P$G
 PATH=C:\;C:\DOS;C:\WINDOWS; (this line is only for use with Windows)
 LH C:\MOUSE\MOUSE.COM

Complete the file by pressing the  F6  function key <ENTER>

The MSCDEX.EXE program is the Microsoft CD-ROM extension that allows a
computer to use a CD-ROM drive.  Every manufacturer of CD-ROM drives
must use this program. The latest version of this driver is 2.21 and
is only available from Microsoft, the CD- ROM drive manufacturer, or
the vendor that sells the CD-ROM drive.  If the sound is choppy, or if
memory is an issue, contact Microsoft, Media Vision, Creative Labs, or
whoever manufactured or sold the CD-ROM drive for the update to this
version. We cannot distribute this file.

MSCDEX has several commands that you might want to know:

/D: Device name.  This name must agree between config.sys and
    autoexec.bat lines. If its "/D:NECCD" in the config.sys file then
    it must read "/D:NECCD" in the autoexec.bat file as well.

/M: Memory buffers.  This value may be reduced for high performance
    CD-ROM drives, or drives that have large read-ahead buffers built
    onto the drive.  The Pro AudioSpectrum's SONY drive can use a
    little as 3 buffers.  Each buffer takes up about 1K , so reducing
    them can save a lot of memory.

/L: Logical drive.  This is the CD-ROM's drive designation.  It should
    be one drive letter above the last hard disk drive.

/E  EMS memory support.  If the computer has Expanded memory this line
    will tell MSCDEX to load itself up into that Expanded memory.
    This will free up a significant amount of conventional memory.

/V  Verbose.  This switch tells MSCDEX to display all of its settings
    when it loads.  Use this setting to help trouble shoot
    installations.

Please contact the appropriate hardware manufacturer for support on
hardware and driver related issues.If you continue to experience any
problems with the Boot Disk, or if you have any questions concerning
any of the above steps, our technical support team will be more than
happy to assist you.  Please call (209) 683-8989 between 8:15 am and
4:45 PM Monday through Friday.  We can also be reached by fax at
