INTERNET TUTORIAL
=================
This document contains important information not available in the
printed documentation or in the online Help. The information below
describes some solutions to problems that you might encounter while
using the program. There are also frequently asked questions and
answers listed below.
============
INSTALLATION
============
The Setup program prepares your computer to run this Internet
Tutorial CD-ROM.
To run the Setup program:
╖ In Windows 95, select Run from the Start menu in other
versions of Windows, select File, then Run.
╖ In the command line, type D:\SETUP.EXE (where D: corresponds
to your CD-ROM drive).
╖ Click OK.
╖ The Setup program creates the C:\XNETUT32 directory
(or one you specify) for you.
╖ For Windows 95, it also copies some DLLs to the
\Windows\System sub-directory.
╖ For earlier Windows versions, it also copies one or more
DLLs and other system files from the \dlls directory on
the CD into the \windows or \windows\system directories
on your hard drive.
NOTE: Newer versions of these files will not be overwritten.
In addition, the Setup program prompts you if you need to install
the latest version of Video for Windows (VFW). After installing
VFWs, you must restart your computer. You may re-install VFW at
any time by running SETUP.EXE in the VFW11 directory on this CD.
You DO NOT need VFW with Windows 95.
The Setup program makes sure that Internet Tutorial is looking
in the right place for the CD drive. If, for example, the drive
letter has changed as a result of a system change (i.e.,if a disk
or other device has been added or removed), then Internet Tutorial
will fail to find its CD-ROM. You can check that the drive letter
is correct by using Windows File Manager (or Explorer for Windows 95)
to see which letter is assigned to the CD drive. Running the Setup
program again will solve this problem.
=============================
VIDEO PLAYBACK CONSIDERATIONS
=============================
For best results on older or slower machines, play the video in
8-bit (256) color mode. Video playback is slower in any video mode
other than 256 colors. Check Windows Setup to ensure that you are
using a 256 color video driver. The Windows Setup is usually in
the Main group of the Windows Program Manager for Windows 3.1, or
under the Display icon from the Control Panel for Windows 95)
You can also improve video playback, and overall program performance,
by increasing the amount of buffer memory that your CD-ROM driver
software uses. Most computers communicate with the CD-ROM drive
through the Microsoft MSCDEX driver (for Windows 3.1). You can
sometimes improve performance by adding /M:64 to the MSCDEX entry
in your AUTOEXEC.BAT file. This increases the number of sector
buffers from the default of 4 to 64.
==========================
SHARE IN AUTOEXEC.BAT FILE
==========================
Unless you are running Windows for Workgroups (3.11) or later
versions of Windows, your AUTOEXEC.BAT file should include the
line: "SHARE /L:500 /F:5100" or something similar. The /L parameter
sets the number of locks, and the /F parameter sets the number of
bytes of file space used to record file-sharing information. The
values shown above are the minimum values required by OLE
applications. Recent versions of Windows do not require this line.

TROUBLESHOOTING
===============
=====
VIDEO
=====
Q: Videos do not play (in earlier versions of Windows before
Windows 95):
A: You may not have the correct driver. Change the driver to
one that works. Internet Tutorial works best in 800 X 600 mode.
=====================================================================
WARNING : SELECTING THE WRONG DRIVER COULD STOP "WINDOWS" FROM
WORKING. MAKE SURE YOU SELECT A DRIVER THAT IS AVAILABLE ON YOUR
SYSTEM. GET HELP IF YOU HAVE NEVER CHANGED DRIVERS BEFORE.
=====================================================================
If video still does not play, make sure you are using the latest
video driver for your video board. Contact your video board
manufacturer for more information. You may also be able to obtain
updated drivers from CompuServe in either the Microsoft forum or
in a forum managed by your video board manufacturer.
Q: Videos do not play under Windows 95:
A: You may not have the correct driver. Internet Tutorial works
best in 800 X 600 mode. Windows 95 makes it easy for you
to change into this mode: click on Display from the Control
Panel, then Settings.
Q: Video looks choppy.
A: Video looks choppy because your CD-ROM drive cannot play
the video fast enough. If your CD-ROM drive does not
generate a fresh picture every fifteen seconds, you can see
the delay between pictures. To speed up video playback:
Q: Soundtracks in the videos are choppy (the people are stuttering).
A: The soundtracks are not keeping up with the videos.
To permanently fix this problem:
╖ Choose the Drivers icon from the Windows Control Panel.
╖ Double-click the line reading, "[MCI] Microsoft Video for
Windows."
╖ Click the checkbox next to the "Skip video frames if
behind" option so that an "X" displays in it.
╖ Click the Set Default button.
If you use older versions of Windows Sound System and other drivers,
the audio may be out of synch with the video. Obtain updated Windows
Sound System drivers from the Windows Driver Library (WDL). For more
information about the WDL, contact Microsoft Product Support. For
third-party drivers, contact your sound board manufacturer's
technical support department to obtain an updated driver.
=====
AUDIO
=====
Q: Audio volume is either too high or too low, and you cannot
adjust it on your speakers.
A: Adjust the volume on your sound card. To adjust the volume
on your sound card when running Windows 95, click the
"sound" icon on the taskbar.
To adjust the volume on your sound card for earlier versions of Windows:
╖ Find the icon for your sound card program group in the
Windows Program Manager. It is usually called "sound" or
something similar.
╖ Find the icon for the Mixer program and run it.
╖ Adjust the volume and/or mix of sounds. Some sound cards
have software that allows you to adjust the volume AND tone
of the sound; start with these tone controls set in the mid
position and your volume level set between 80 - 100%. This
should give a clear signal with no distortion. If treble
or bass is added in this software, you must reduce the
volume to compensate, or distortion will occur. Check your
sound card manual for the optimum settings.
Q: Audio does not play.
A: Make sure that the volume for your speakers is set to an
audible level. If your system has a mute option, make sure
it is not in effect. If audio still does not play, check
that your sound board is set up correctly. Check to see
that the audio driver that came with your sound board is
installed correctly and, if necessary, reinstall it.
See the documentation that came with your sound board for
more details.
======
MEMORY
======
Q: You receive an Out-of-Memory error.
A: Close all unnecessary applications. You may find more
memory becomes available if you restart Windows. If you
are running Windows 3.x in Enhanced mode (the default mode
if you are running Windows 3.x on a 386 or better machine),
create a permanent swap file on your hard disk. A swap
file uses some hard drive space as memory.
NOTE: If you have not defragmented your hard drive in a while,
be sure to do so BEFORE creating a swap file. Otherwise,
Windows may not be able to find a large enough area of
disk space to use as memory. Use the DOS DEFRAG command,
or another utility to defragment your hard drive.
To create a swap file:
╖ Double-click the 386 Enhanced icon in your Windows Control Panel.
╖ Click the Virtual Memory button on the right.
╖ If you don't see the word "Permanent" in that box, click the
╖ Change>> button and select Permanent in the Type field.
Q: Internet Tutorial, like other Windows applications, stores
temporary files in the \TEMP directory on the hard drive.
Ordinarily, Internet Tutorial will clear this directory
automatically. In case of a program or system failure, you
may have to delete temporary files manually.
A: To check the \TEMP setting and/or delete temporary files:
╖ Exit from Windows.
╖ At the MS-DOS prompt, type SET and press <Enter>. This
gives you a listing of the MS-DOS environment settings.
╖ Confirm that one of the settings is TEMP= followed by a
valid path.
╖ When you find the TEMP= setting, check the amount of disk
space available on the drive where your temporary directory
resides.
╖ If you do not have enough disk space, delete unnecessary
files from the drive, or move the \TEMP directory to a
partition that has enough disk space and change the SET
TEMP= line in the AUTOEXEC.BAT file. Usually, it should
read something like "SET TEMP=C:\TEMP".
╖ Reboot your machine after modifying the AUTOEXEC.BAT file.
=======
DISPLAY
=======
Q: Versions of ATI's video accelerator prior to 2.1 do not
work well with Video for Windows version 1.1. Installing
the accelerator software after installing Video for Windows
can overwrite Video for 1.2. Windows version 1.1 components
with components from the previous version.
A: Avoid installing any version of the video accelerator unless
it is specifically noted to be compatible with Video for
Windows version 1.1. To obtain an updated version, you can
contact ATI's customer support at (905)882-2626.
Q: Your customization data has been lost or corrupted. This data
is stored in a file called utitle.ttl in your C:\XNETUT32
directory (or the directory you created during setup).
A: The latest version of the INTERNET TUTORIAL program always
saves a backup copy of your customization data in a file
called utitle.bak in same directory as the utitle.ttl file.
Copy this file to utitle.ttl.
