Introduction to the User’s Guide
The User’s Guide includes general information about your computer,
troubleshooting, upgrades, diagnostics information, and technical
specifications.
Your Compaq computer comes with Windows 98 already installed on
the hard drive. After you set up your computer according to the Setup
Poster, refer to Setting up Your Software in the Getting Started
Guide for a screen-by screen description of software setup on your
Compaq computer. If you are already familiar with the setup process,
you should still refer to the hints in this section prior to beginning the
process.
You will need the following information during the setup process:
Regional settings (the language you want to use during the setup
process). Your software language is determined by the product
that you ordered.
Information about your name and company
Product Key number from the Certificate of Authenticity
You will find the Product Key printed in a bar code on your
Certificate of Authenticity, which appears on the front of the
Windows 98 booklet that came with your computer.
Your time zone, the date, and the time
chapter
12Users Guide
Throughout the setup process, follow these hints:
Always use the left mouse button during the selection process.
Do NOT install a printer, printer drivers, or any other type of
drivers until AFTER the initial setup process is complete.
Attempts to do so will disrupt the setup process.
If you get a Printer Install screen, select Cancel.
Prior to or during the setup process, do not attempt to install
additional software or to attach any external devices or drives
(such as printers and ZIP drives, or printer drivers on CD).
Once the setup process begins, do not interrupt the process, turn
the power off, or bump or unplug the power cord. If the process is
abruptly stopped or interrupted, you may have to install the
system using the Quick Restore CD, which will take longer.
If the screen goes blank or nothing appears to be happening, look
at the drive activity light or the screen for an hourglass. If lights
are blinking or you see an hourglass, the setup process is
continuing. If the computer locks up for more than one hour and
will not continue the setup process, restart the computer to
continue setup. Turn the computer off by pressing the Power
button. Do not use Ctrl+Alt+Del to turn off your computer.
If you have other questions related to your Windows 98 software,
refer to your software documentation.
CAUTION: Installing a printer may disrupt the setup process. Aviod
printer installation until after the initial setup process is complete.

DVD-ROM Problems
This feature is not currently available for Windows NT.
DVD-ROM Problems
Problem Possible Cause Solution
Certain files on a DVD disk will
not play using the MediaPlayer
The MediaPlayer does not initiate
the authentication process
necessary for playback of DVD
files. Attempts to play these files
will result in no video being
played.
Use the DVD Player to play all
content. This is the correct way to
view all DVD files.
A DVD disk inserted in the DVD-
ROM drive with DVD Player
running will not play
In the drivers for most DVD-ROM
drives there is an Auto-Insert
Notification option that is turned
on by default. This option lets the
operating system know when a
DVD or compact disk is inserted
into the DVD-ROM drive. The
purpose of the feature is to begin
running software or to begin
playback of a disk when it is first
inserted into the drive without the
need for running an application.
If this option is turned off, the
DVD Player application does not
know that you inserted a DVD
disk.
To turn this option on, use the
following procedure:
1. Click StartSettingsControl
Panel.
2. Double-click the System icon;
then select the Device Manager
tab.
3. Locate the CD-ROM listing, and
click the entry for your DVD-
ROM drive.
4. Click the Properties button and
then the Settings tab.
5. Locate and click the checkbox
labeled Auto Insert Notification.
6. Click OK to save the change.
7. Restart Windows 98, if
necessary, for the change to
become active.
When playing a DVD, you get an
invalid/illegal region code
message

region.
If you have already selected a region
code permanently, you will be unable
to change it.
