QUICK TIPS FOR AN ERROR-FREE SETUP
Disable all antivirus programs running on your system.
If these utilities are left running during Setup, your
system may stop responding.

NOTE: Some systems have antivirus capabilities built
into the system. If this option is left enabled in
BIOS/CMOS settings, you may receive a warning about
"virus-like activity" or "Master Boot Record" changes.
You must allow these changes to take place for Setup
to complete successfully. See your antivirus software
documentation for more information.

Run ScanDisk to check and fix any problems with your
hard disk(s).

Close all running programs. This includes disabling
any screen savers, Advanced Power Management settings,
and other programs that may cause Setup to stop
responding. To assure a clean upgrade from in
Windows 95, press CTRL+ALT+DEL and "End Task" on
all running programs except SYSTRAY and EXPLORER
before running Setup. See "Performing a Clean Boot"
for more information.

GENERAL SETUP ISSUES
If you have the Number Nine Imagine 128 Display
Adapter, or the STB Velocity 128 3D AGP (Nvidia
Riva 128), you should run Setup from MS-DOS or
change your display driver to VGA.

Upgrade vs. Full install versions of Windows 98.
If you have the Upgrade version of Windows 98,
Setup will attempt to find a qualifying upgrade
product on your system. If Setup fails to find a
previous version of Windows, you will be prompted
to insert your previous media for proof of
compliance.

Disk Space requirements for Windows 98.
Because there are many factors that go into
calculating the amount of free space required for
Windows 98, these figures are only estimates based
on typical Windows 98 installs.

Typical upgrade from Windows 95: requires approximately
  195 MB of free hard disk space, but may range
  between 120 MB to 295 MB, depending on your system
  configuration and the options you choose to install.
Full install of Windows 98 on a FAT16 drive: requires
  225 MB of free hard disk space, but may range between
  165-355 MB depending on system configuration and
  options selected.
Full install of Windows 98 on a FAT32 drive: requires
  175 MB of free hard disk space, but may range between
  140 MB - 255 MB, depending on system configuration and
  options selected.

Also, if you are installing Windows 98 to a drive
other than C, Setup can require up to 25 MB of free
disk space on drive C for the system and log files
created during Setup.

Uninstall: If you wish to back up Windows 95 before upgrading, select the
Save Your System Files option during Setup. This
will allow you to uninstall Windows 98 in the event you
have problems. However, there are certain cases in which
you cannot do this:

* Your current Windows installation is on a
  compressed drive.
* You are installing to a new directory or setting
  up a clean install with no previous version available.
* You are running a version of MS-DOS earlier
  than 5.0.

MAKE A NEW STARTUP DISK! Because of changes in the
real-mode and protect-mode kernels to support FAT32,
Windows 98 startup disks are not compatible with earlier
versions of Windows. Therefore, when you set up
Windows 98 for the first time, be sure to make a
new Startup Disk, EVEN IF YOU ARE NOT PLANNING TO
USE FAT32.

Program Manager from Windows 3.x.

Program Manager is no longer supported in Windows 98.
Program Manager (Progman.exe) is left on the system
for troubleshooting purposes, but it will NOT contain
any groups. In addition, if you are upgrading over
Windows 95, your existing .grp files will be removed.
These are known to cause some problems when installing
Windows 98. If you are upgrading from Windows 3.x,
the old .grp files will remain on the system and
Program Manager will still have some functionality.
You should back up your existing progman.ini and *.grp
files before upgrading to Windows 98 if you intend to
use Program Manager.

INSTALLING WINDOWS 98 FROM MS-DOS

If you are starting with a clean or new hard disk or
if you have problems running Setup from your previous
version of Windows, you may have to run Windows 98
Setup from MS-DOS. Although installing from MS-DOS is
typically the slower method of installation, it is
often the safest and should be used when other types
of installations fail.

MS-DOS Boot Hot Keys:
There are several ways to boot your system to an
MS-DOS command prompt safely. The easiest way is by
using these hot keys:

* Windows 98
Hold the CTRL key down while your computer is booting.
This will take you directly to the Windows 98 Boot
Menu (the F8 key is still functional, but there is
no "Starting Windows 98" prompt in Windows 98, so
it's hard to know exactly when to press it).

* Windows 95
Press the F8 key at the "Starting Windows 95" prompt.
This will take you to the Windows 95 Boot Menu.

* MS-DOS 6.x
Press the F8 key at the "Starting MS-DOS" prompt. This
will allows you to manually choose which drivers to
load or to bypass your system files.

* Real-mode CD-ROM drivers
You will need real-mode CD-ROM drivers loaded so you
can access the Windows 98 CD. If you have run
Windows 98 Setup before and have created a Startup
Disk, you can use the CD-ROM drivers included on that
disk. If you do not have a Startup Disk, you will
need to run the installation program that came with
your CD-ROM hardware.

After you have access to your CD-ROM drive, you can
switch to the drive containing the Windows 98 CD
and type: SETUP. Setup should now continue.


Tips for Installing Real-Mode CD-ROM Drivers:

Currently running Windows 95:
If you are currently running Windows 95, you may
already have a portion of the CD-ROM drivers loaded.
If you can shut down to MS-DOS mode and get access
to your CD-ROM drive, try the following:

* Reboot and press the F8 key at "Starting Windows 95".
* Choose "Command Prompt Only."
* At the C:\ prompt type: DosStart.bat.

You should now have access to your CD-ROM drive.

Lost access to the CD-ROM drive during Setup:
If you lose access to your CD-ROM during Windows 98
Setup, you can try the following:

* Reboot and press the F8 key at "Starting Windows 95,"
  and then choose the option for Command Prompt Only. If
  you are running MS-DOS, boot directly to command prompt.
* Edit the Autoexec.bat file by typing: Edit Autoexec.bat
* Delete the text "Rem by Windows 98 Setup" in front of
  the line that includes the reference to Mscdex.exe.
* Exit Edit by typing ALT-F-X and save the file when
  prompted.
* Reboot. Either Setup should continue on its own, or
  you should run Setup again, choosing Safe Recovery if
  prompted.

Running Windows 98 Setup from Your Hard Disk:

By copying all the Setup files to your hard disk and
then installing from your hard disk, you can eliminate
most of the problems associated with file copy and disk
I/O issues. You can unload your CD-ROM drivers and free
up conventional memory to assist with low memory errors
in this type of install. To copy the Setup files locally:

From Windows 95:
* Free an additional 120 MB of disk space in addition
  to what Setup will require. Setup will typically
  require 195 MB for an upgrade from Windows 95.
* Create a temporary folder to store the Setup files
  on that drive.
* Copy the contents of the Win98 folder on your
  Windows 98 CD to the temporary folder you just created.
  You should also copy the Win98 subfolders, but this is
  not essential if you are short on disk space.
* Reboot. Press the F8 key at "Starting Windows 95" and
  choose Safe Mode Command Prompt Only.
* Now, switch to the temporary folder containing the
  Windows 98 Setup files and type: SETUP.

From MS-DOS:
* Make sure you have access to your CD-ROM drive. See
  above for more information.
* Free an additional 120 MB of disk space in addition
  to what Setup will require. Setup will typically
  require 195 MB for an upgrade from Windows 95.
* Create a temporary folder on the drive with plenty
  of free space to store the Setup files. To create a
  temporary directory, switch to that drive letter and
  type: MD Win98tmp.
* Now, switch to the Windows 98 CD-ROM drive and the
  Win98 directory by typing: <drive letter>\Win98.
* Then copy the Windows 98 Setup file to the temporary
  directory you just created by typing:
  Copy *.* <drive letter>\Win98tmp
* After all the files are copied, restart your system
  and perform a clean boot by bypassing your startup
  files. See "Performing a Clean Boot" for more
  information.
* Switch to the temporary directory you just copied
  the files to and start Setup by typing: SETUP.

Performing a Clean Boot:

Third-party device drivers, utilities, or other programs
can prevent a successful install. Clean-booting your
system can fix many of these problems. You can perform
a clean boot by:

Using a floppy disk to start your computer:

* Boot from a Windows 98 Startup Disk. This disk allows
  the option for loading with or without CD-ROM drivers
  and is a clean environment for running Setup.
* Boot from a previous Windows 95 or MS-DOS boot disk.
  This does not give access to your CD-ROM drivers, but
  can be used if you copy the Setup files to your hard
  disk as described above.

Windows 95 Safe Mode Command Prompt Only:

* Boot your system and hold the F8 key at the "Starting
  Windows 95" prompt.
* Choose Safe Mode Command Prompt Only. This also does
  not provide access to your CD-ROM drive, but can be
  used if the Setup files are copied to your hard disk
  as described above.

Windows 98 step-by-step boot:

If you want to load some drivers manually, do this:
* Boot your system and hold the F8 key at the "Starting
  Windows 95" prompt.
* Choose the Step by Step option.
* Now, only say YES to devices you want to be loaded. In
  most cases, you should say YES to Himem.sys

Windows 95/MS-DOS Clean boot with more memory:

You can increase the amount of memory available by making
the following modifications to your Config.sys file. You
can also make these changes to your Boot Disk as well.
NOTE: These are the only drivers you should load.

Device=Himem.sys
Device=EMM386.exe noems
Dos=high,umb
Device=drvspace.sys /move
 (Optional - only if using DriveSpace compression)

Creating a Windows 98 Startup Disk:

If Windows 98 Setup fails after copying most of the files
to your hard disk, you may be able to create a Startup
Disk by using the bootdisk.bat utility.
* Boot to an MS-DOS prompt.
* Change directories to your Windows\command directory.
* Run the Bootdisk.bat program that will prompt you to
  create a Startup Disk.

This disk contains generic real-mode CD-ROM drivers that
may be useful when running Setup again.

ANTIVIRUS SOFTWARE

Make sure that no antivirus program is running while you
are setting up Windows 98. If the program is a
terminate-and-stay-resident program, remove any references
to it in your Autoexec.bat, Config.sys, and Win.ini files.

If your BIOS has built-in virus protection, disable it
before running Setup. To disable it, you must use the
CMOS setup program for your BIOS. For more information,
see your computer documentation.

See the notes for specific antivirus programs below.

CMOS/BIOS-enabled virus protection:

Some systems come with virus protection built into the
system. If this is left enabled, you may be warned with
"Virus-like Activity" or "Master Boot Record Changed"
messages. You must allow these changes to take place. If
you choose to restore the previous settings, your system
may no longer boot.

Norton AntiVirus:

If Norton AntiVirus is installed, you may see the
following warning at the end of the initial file copy
procedure:

 Application Wininst0.400\Suwin.exe is
 attempting to update the Master Boot Record

You should choose Continue (C) for Setup to finish
properly. If you do not allow these changes to take place,
Setup may stop responding.

Dr. Solomon's AntiVirus:

If you are running Dr. Solomon's AntiVirus utility, you
may receive a blue screen fatal exception error in Ios.vxd
while trying to create a Startup Disk during Setup. You
should click Cancel on the Startup Disk screen when the
progress bar is at 20%. This will allow Setup to continue.
Look for an update to Dr. Solomon's AntiVirus software on
their Web site to resolve this issue.

FINDING AND FIXING HARD DISK PROBLEMS DURING SETUP
(USING SCANDISK)

Finding problems during Windows 98 Setup
The version of Scandisk run during Windows 98 Setup only
checks for errors. It does not fix them. If there are
problems, Setup cannot continue until they are fixed.
To fix these problems, quit Setup and run ScanDisk from
Windows 95 or MS-DOS. See below for more information
about using ScanDisk to resolve these issues.

Fixing Hard Disk Problems:

If, during Setup, you see a message telling you that you
must run ScanDisk to fix problems on your hard disk,
follow these steps to fix the problems.

If you are setting up Windows 98 over MS-DOS or a
previous version of Windows, such as Windows 3.1:

1. Quit Windows.

2. If you are setting up from floppy disks, insert
   Setup Disk 1 into the floppy drive, and then type
   the following at the command prompt:

 a:scandisk.exe /all

   where "a" is the drive that contains the Windows disk.

3. If you are setting up from a CD, insert the CD, and
   then type the following:

        d:\win98\scandisk.exe /all

   where "d" is the drive that contains the CD.

4. Follow the instructions on your screen, and fix any
   problems that ScanDisk finds.

5. Start Windows, and then run Setup again.

If you are setting up Windows 98 over a previous version
of Windows 98 or Windows 95:

1. Quit Setup.

2. On the Start menu, point to  Programs, point to
   Accessories, point to System Tools, and then
   click ScanDisk.

3. Check your hard disks and any host drives you have
   for errors, and repair any problems found. Be sure
   to do a complete surface scan on all your drives,
   or Setup may still find errors.

Problems Running ScanDisk:

There are certain cases where ScanDisk may not be able
to fix an issue or is producing errors.

You are running DriveSpace 3 compression:

If Drvspace3 compression is installed on your system,
you may be low on conventional memory. To free up memory,
you may try the following:

* If you are running MS-DOS 6.x, you can run Memmaker.exe
  to free enough memory for ScanDisk to complete.
* See "INSTALLING WINDOWS 98 FROM MS-DOS" on how to perform
  a clean boot with more memory.
* Check your drives while running Windows 95.

If you still don't have enough memory, or if you have
other problems while Setup is running ScanDisk, you can
bypass ScanDisk in Setup by running Setup with the /IS
option. To do this, type the following command:

 setup /is

NOTE: Bypassing ScanDisk during Setup is not recommended.
If you do, there may be problems with your hard disk
that could cause Windows 98 not to install or run
correctly.

REMOVING WINDOWS 98

Saving System Files:
Windows 98 Setup offers users the option of backing
up their previous version of Windows in case Windows 98
needs to be uninstalled later. To enable this option,
you must select the Save Your System Files option when
prompted during Setup. Setup will then create the
following hidden files necessary to uninstall Windows 98:
  * Winundo.dat
  * Winundo.ini
  * Winlfn.ini

NOTE: Deleting these files will prevent Windows 98
from being uninstalled.

If any of the following apply, you will not be able
to Uninstall Windows 98, and Setup will not prompt you
to Save System Files:

* Your current Windows installation is on a compressed
  drive.
* You are installing to a new directory or a clean
  install with no previous version available.
* You are running a version of MS-DOS earlier than 5.0.

NOTE: The files necessary to remove Windows 98 must
be saved on a local hard drive. You cannot save them
to a network drive or a floppy disk. As long as two
or more drives have adequate free space, you can
select the drive to which to save the uninstall
information.

There are also several actions that could prevent
Windows 98 from being uninstalled after Windows 98
Setup is complete. The following is a list of items
that will cause the uninstall information to be removed
from your system:

* Converting your hard disk to FAT32
* Compressing your hard disk with DriveSpace

NOTE: These utilities should warn you that the Uninstall
information will be lost before they perform conversion or
compression.

Removing Windows 98:

To remove Windows 98 and completely restore your system
to its previous versions of MS-DOS and Windows 3.x, or
Windows 95:

1. Click Start, point to Settings, and then click Control
   Panel.
2. Double-click Add/Remove Programs.
3. On the Install/Uninstall tab, click Uninstall Windows 98,
   and then click Add/Remove.

Or, if you are having problems starting Windows 98,
use your Startup Disk to start your computer, and then
run UNINSTAL from the Startup Disk.

NOTE: UNINSTAL needs to shut down Windows 98. If there
is a problem with this on your computer, restart your
computer and press F8 when you see the message "Starting
Windows 98." Then, click Command Prompt Only and run
UNINSTAL from the command prompt.

If Setup did not complete successfully and you want to
restore your previous versions of MS-DOS and Windows 3.x,
or Windows 95, you can run UNINSTAL from the
\Windows\Command directory on your hard disk, or from
your Startup Disk.

If you saved your files on a drive other than C, you
can use the /w option to specify the drive where the
files are located. For example:

        uninstal /w e:

where e: is the drive containing your previous system
files.

If Windows 98 is running and you want to remove the
uninstall files to free disk space, follow these steps:

1. Click Start, point to Settings, and then click
   Control Panel.
2. Double-click Add/Remove Programs.
3. On the Install/Uninstall tab, click Old
   Windows 3.x/MS-DOS System Files, and then click
   Remove. Or click Remove Windows 95 system files
   (Uninstall Info).

You can no longer remove Windows 98.

IF YOU HAVE A COMPRESSED DRIVE

If you have compressed your hard disk, you
may get a message that there is not enough space on
the host partition of the compressed drive. Setup may
have to copy some files to your startup drive, the host
for your startup drive, or the host for your Windows
drive. If you get this message, free some space on the
specified drive, and then run Setup again. Try one of the
following:

* Set up Windows on an uncompressed drive if possible.

* Delete any unneeded files on your host partition.

* If you are running Windows 3.1 and have a permanent
  swap file, try making it smaller. In Control Panel,
  double-click 386 Enhanced, and then click Virtual
  Memory. Modify the size of your swap file.

* Use your disk compression software to free up some space
  on the host drive for the compressed drive. If you
  compressed your drive by using DriveSpace or DoubleSpace,
  follow these steps:

  1. Quit Windows.
  2. Run Drvspace.exe or Dblspace.exe.
  3. Select the compressed drive on whose host you want
     to free space.
  4. On the Drive menu, click Change Size and adjust the
     free space as necessary.

  If you compressed your drive using Windows 95 Drivespace,
  or Drvspace3 from Plus!, follow these steps:

  1. Start Windows
  2. Select Drivespace from
     Start/Programs/Accessories/System Tools/Drivespace.
  3. Select the compressed drive on whose host you want
     to free space.
  4. On the Drive menu, click Change Size, and then adjust
     the free space as necessary.

If you used other compression software, such as Stacker,
consult the software documentation.

NOTE: You may notice a discrepancy in the amount of free
space reported by Setup and the amount of space you think
is available on your host drive. Windows uses some space
for creating a swap file. This space may not appear to be
allocated when Windows is not running.

NOTE: If you create a Startup Disk during Setup, make
sure you do not use a compressed disk for the Startup Disk.

INSTALLING WINDOWS 98 ON A SYSTEM RUNNING WINDOWS NT

You cannot install Windows 98 over any version of
Windows NT, but they can exist together on a single
system. However, for compatibility reasons, it is
recommended that you install each to a separate hard
disk or partition. If Windows NT is already installed,
Windows 98 Setup will add itself to the Windows NT boot
menu to allow the user to multi-boot between Windows 98
and Windows NT.

If you can no longer boot Windows NT, you should boot
from the Windows NT recovery disks and choose the Repair
option to restore the Windows NT boot files.

When installing Windows 98 on a system with drives
created with Windows NT, you may receive the following
error:

"Setup has detected that your hard disk has a 64K-cluster
FAT partition. Because ScanDisk does not work on disks
with this cluster size, Setup cannot continue. To complete
Setup , you must repartition your hard disk, format the
partition with a FAT file system that has a cluster size
of 32K or less, and then restart Setup."

Running Setup with the "/is" parameter (e.g., Setup /is)
will bypass ScanDisk and avoid this problem.

INSTALLING WINDOWS 98 ON A SYSTEM RUNNING OS/2
Setup will not run on OS/2. You need to start MS-DOS
and run Setup from the MS-DOS prompt.

NOTE: If you are upgrading over OS/2 on an HPFS partition,
you must have your OS/2 disk 1 available during Setup.

If you start MS-DOS from a floppy disk and then run
Setup, you will no longer be able to start OS/2 after
Windows 98 has been installed. You must delete the
Autoexec.bat and Config.sys files that OS/2 uses before
running Windows 98 Setup.

If you want to remove OS/2 from your computer after you
have installed Windows 98:

1. Back up the data files you want to keep onto a
   floppy disk or network drive.
2. Delete the files in each of your OS/2 directories and
   subdirectories, and then delete the OS/2 directories.
3. In My Computer or Windows Explorer, click View, click
   Options, and click Show All Files. Then, delete the
   following OS/2 files:

 Ea data.sf
 OS2ldr.msg
 OS2krnl
 OS2boot
 Wp data.sf

SETUP ERROR MESSAGES

This section lists specific messages that you may
encounter during Setup and provides information about
what to do next.

"Previous version of Setupx.dll" message:

Setup detects that an earlier version of SetupX.dll or
NetDi.dll is in use. This may be because there are open
applications on your computer. If you want Setup to
replace the existing file and automatically restart
your system, click OK. Or, to keep your existing version
of SetupX.dll and NetDi.dll, click Cancel to quit Setup,
close any open applications, then run Setup again.

Several programs are known to cause this error:

* Diamond's "In Control Tools"
* Ensonics AudioPCI sound card drivers
* Aztech sound card drivers
* Hayes Modem configuration utilites
* Some Windows Printing System utilities
  (Canon BJ series)

If Windows 98 Setup still gives this error after
rebooting, you should run Setup from the MS-DOS command
prompt. See "INSTALLING WINDOWS 98 FROM MS-DOS" for more
information.

Message SU0018

"Setup cannot create files on your startup drive and
cannot set up Windows 98. There may be too many files
in the root directory of your startup drive, or your
startup drive letter may have been remapped."

The root folder of a drive holds a maximum of 512 entries
(files or folders). This message indicates that Setup
has detected too many directory entries in the root
folder of your computer, and Setup cannot create the
files it needs to set up Windows 98. Move or delete
some files from the root folder of your drive, and
then run Setup again.

This error message can also appear if your startup
drive letter has been remapped. Several things could
cause this:
* You have mapped a network drive to C. If this is the
  case, remap the network drive.
* You have a LastDrive=C: statement in your Config.sys
  file. Remove the LastDrive statement, or set it to equal
  another drive.
* A third-party partitioning or boot manager program has
  remapped the drive. Consult the program documentation.
  You may need to uninstall the program before installing
  Windows 98.

"Unrecoverable Setup Error" Message
"Unrecoverable Setup Error. Setup cannot continue on this
system configuration. Click OK to quit Setup." This error
could be caused by various conditions. See "General Setup
Notes" and "INSTALLING WINDOWS 98 FROM MS-DOS" for more
information.

Long File Names Error Messages
If you see the message "Setup has detected that the
program, Long File Names, is installed in this directory.
Setup cannot continue." quit Setup, and then remove Long
File Names from your computer by using the Uninstall feature
in Long File Names. See "View Software" for more information.

Not Enough Memory Messages
If you encounter an Out of Memory message, you can
increase conventional memory by commenting out TSRs
and loading device drivers into the upper memory area.
For information on how to perform these steps, see
Microsoft Knowledge Base Article Q134399, "How to
Increase Conventional Memory for MS-DOS-Based Programs" at
http://support.microsoft.com/support/kb/articles/q134/3/99.asp

Not Enough Disk Space Messages
You can recover disk space by completing any or all of
the following steps:

* Right-click Recycle Bin, and then click Empty
  Recycle Bin.

* Delete the contents of your Internet browser cache
  folder.

* Delete files with the extensions .bak and .tmp.

* Delete unused program folders (be sure to back up
  data first).

* Delete the old MS-DOS folder, unless you intend to
  configure your computer to run both Windows 98 and
  MS-DOS. (First, be sure you have a start disk that
  supports access to the CD-ROM drive.)

* Delete the hidden file Winundo.dat from the previous
  installation of Windows 95.

* Delete the old Windows 3.1 folder, unless you intend
  to configure your computer to run both Windows 3.1
  and Windows 98.

Setup Cannot Write to the Temporary Directory
This message may appear because there is insufficient
disk space for the temporary directory. If space is
available on another drive, use the following command
line to change the temporary directory location:

 Setup /T:<drive letter>:\TEMP

If you do not have space available on another drive,
free some disk space, and then run Setup again. See
the "Not Enough Disk Space" Messages section for
files that can be deleted.

CAB File Error Messages
CAB file errors are most frequently caused by one or
more of the following: virus, low conventional memory,
bad media, or hardware, especially CD-ROM drives.

If you already created a Startup Disk, quit Setup,
shut down your computer, insert the Startup Disk, and
then restart the computer. This action creates a
controlled environment from which to run Setup. Then
run Setup from the MS-DOS command prompt.

To recover from corrupt CAB file error messages, try
copying the Setup files to your hard disk and running
Setup from your hard disk, using these steps:

1. You need an extra 200 MB free on your hard disk
   and a temp directory to store files.
2. Boot off the Windows 98 Startup Disk and choose
   the option to load your CD-ROM drivers. If you
   do not have access to your CD-ROM drive when
   booting off the Windows 98 Startup Disk, you
   must load the drivers that came with your CD-ROM
   drive.
3. Change drives to the CD-ROM drive letter indicated
   by the MSCD001 prompt on the screen and switch to
   the Win98 folder. Type: Copy *.* <destination drive
   and the temp folder you created>
4. Change to that folder and run Setup, choosing Safe
   Recovery if prompted.

See "INSTALLING WINDOWS 98 FROM MS-DOS" for more information.

If you have Multimedia Cloaking and are installing
Windows 98 from floppy disks, Setup may not run
successfully. If you see messages about Setup not
being able to read .cab files, follow these steps:

1. Remove the line referencing Cacheclk.exe from
   your Config.sys and Autoexec.bat files.
2. Restart your computer.
3. Run Setup again.

Message SU0010, SU0012, SU0015, or SU0016
If you receive one of these messages during Setup,
see  "Installing Windows 98 on a System Running
Windows NT" and "Installing Windows 98 on a System
Running OS/2" for more information.

Message SU0011
If your hard disk is password-protected, Setup will
not complete successfully. You must first remove the
password protection. For more information, see your
computer documentation.

Message SU0013
To set up Windows 98, your startup drive must be
an MS-DOS boot partition. If your startup drive is
formatted as HPFS or NTFS, you must create an MS-DOS
boot partition before running Setup. For more
information about creating an MS-DOS boot partition,
see your computer documentation.

You may also receive this error if you have third-party
partitioning software such as EZ drive or Disk Manager
installed. If so, reboot your system and run Setup
from an MS-DOS command prompt. For more information,
see "Running Setup from MS-DOS."

Standard Mode Messages
If you get any of the following error messages, remove
any memory managers (such as EMM386.exe, QEMM, or 386Max)
from your Config.sys file, and then run Setup again.

 Standard Mode: Invalid DPMI return.
 Standard Mode: Fault in MS-DOS Extender.
 Standard Mode: Bad Fault in MS-DOS Extender.
 Standard Mode: Unknown stack in fault dispatcher.
 Standard Mode: Stack Overflow.

NOTE: If you still have problems, add EMM386.EXE back
into your Config.sys file and exclude all ranges. For
example,

 device=c:\windows\emm386.exe x=A000-FFFF

If you encounter these messages or if your computer stops
responding during Setup, turn on double-buffering in
SmartDrive. Several SCSI hard drives and some ESDI drives
require double-buffering.

To turn on double buffering, add the following line to
the beginning of your Config.sys file:

 device=c:\windows\smartdrv.exe /double_buffer+

where "c:\windows" is the path to your Windows directory.

"Setup Could Not Back Up Your System Files" Message
If you see this error message while Setup is saving
your system files, you may not have enough disk space,
particularly on compressed disks. Free up space on the
drive you are saving your system files on (the default
drive is C) by removing unneeded files.

Uninstall can require up to 75 MB on many systems. If
Setup is not offering you the choice of saving your
system files, you may be very low on free disk space.

"Cannot Continue on This System Configuration"
If you get this message, you may have an older,
incompatible disk partition. Before you run Setup,
you will need to back up your data and then repartition
your disk.

Message SU0167
A file or folder called Desktop exists on your computer.
Rename or move your current Desktop folder, and then
run Setup again.

Message SU0410
Setup cannot open a required file, possibly because the
file is missing or damaged, or because your computer
does not have enough memory.

If you have already created a Startup Disk, quit Setup,
shut down your computer, insert the Startup Disk, and
then restart the computer. Then, run Setup from the
MS-DOS command prompt.

"Cannot Copy File" Messages
Try skipping the file; it may not be essential. If Setup
does not complete successfully, or Windows 98 will not
run, quit Setup, shut down your computer, insert the
Startup Disk into the floppy drive, and restart the
computer. Then run Setup from the MS-DOS command prompt.

SU99xxxx Messages
SU99 is a prefix that is added to all errors that Setup
does not have a specific error message for. These errors
are often caused by low conventional memory. If you have
already created a Startup Disk, quit Setup, shut down your
computer, insert the Startup Disk, and restart the computer.
Then, run Setup from the MS-DOS command prompt.

"Setup does not have enough conventional memory to check your
computer's hard disks."

-or-

"Setup could not check the hard drives on your computer."

If you receive either of these errors, Setup was unable to
run ScanDisk to check your hard drives. This could be because
of low conventional memory or your disk contains errors that
Scandisk cannot fix when run from Setup. To work around these
errors, reboot your system to MS-DOS mode and run ScanDisk
/all. Then, run Setup again. If Setup still fails, reboot
to MS-DOS mode and run Scandisk /all /surface. This will take
a little longer, but it will ensure your hard disks are in
good shape. If, after running ScanDisk with these options,
Setup still won't continue, you should run Setup /is to bypass
ScanDisk.

NOTE: Bypassing ScanDisk is not recommened and should only be
used if you are positive your disk(s) contain no errors.  If
there are still errors, Setup may fail and your system may no
longer boot.

EDITING THE CONFIG.SYS AND AUTOEXEC.BAT FILES
Your computer's Config.sys and Autoexec.bat files tell
your computer what programs and devices to load on
startup (for example, a virus-scanner program to
Autoexec.bat file may direct your computer to automatically
load). Windows 98 Setup will not run properly with some
programs and devices. To remove or disable such a program
or device, you may need to edit the Config.sys and/or
Autoexec.bat files.

To edit the Config.sys and Autoexec.bat files:

1. In Windows 3.1 or 3.11, click File, click Run, type
   Sysedit, and then press ENTER. In Windows 95, click
   Start, click Run, type Sysedit, and then press ENTER.

2. In the Config.sys or Autoexec.bat dialog box, type
   REM at the beginning of any line(s) that you want
   to disable.

3. Save changes and restart your computer.

HARDWARE NOTES
This section includes notes on specific system
configurations that may prevent Setup from installing
Windows 98 successfully.

Sager NP8200 or Wedge Technologies 466/DX2
IMPORTANT: If you install Windows 98 on a Sager
NP8200 or Wedge Technologies 466/DX2 laptop
computer, you will not be able to use your
computer, even if you reinstall a previous
version of Windows.

Plug and Play Network Cards and 16-Bit Real-Mode Drivers
When you need to run the 16-bit real-mode driver for
your network interface card (NIC) (which is common if
you use DLC or another real-mode protocol), your Plug
and Play card may appear not to function because the
16-bit NIC drivers load before Windows 98 has a chance
to turn on Plug and Play cards. In addition, some
16-bit NIC drivers do not recognize Plug and Play
cards (most NE2000 Plug and Play clones fall into
this category).

>>>To use your Plug and Play card with a 16-bit
   NIC driver:

1. Run the Softset utility that comes with your Plug
   and Play card, and then set the card to non-Plug
   and Play mode.

2. Double-click Network in Control Panel, and then
   remove the network card.

3. In Control Panel, double-click Add New Hardware and
   follow the instructions on your screen. Windows 98
   will detect your network card.

If you change to a 32-bit protected-mode NIC driver
in the future, you can run Softset again to turn on
Plug and Play mode for your card.

Intel EtherExpress 16 NICs and PCI Computers
Your system may not respond or you may experience
initialization problems if you are using an Intel
EtherExpress 16 NIC in a PCI computer with certain
Diamond Speed Star PCI video cards. These problems
are not related to Windows 98; they occur on a variety
of operating system platforms. If you experience other
problems with your EtherExpress 16 in a PCI computer,
replace the card before you report the problem to
Microsoft.

If you have one of these video cards, contact your
vendor about getting a new video BIOS update.

- Diamond Speed Star PCI video card with BIOS
  version 1.01
- Diamond Viper PCI VGA Video Adapter
- Diamond Stealth video card, Bios v1.03

IBM Thinkpad Model 750x/755x/360x
If you have one of these models (including submodels
such as C, CE, CX, CS, and CSE), before you install
Windows 98 check the IBM bulletin board or the THINKPAD
forum on CompuServe for updated BIOS and/or Mwave
drivers for your computer.

If you don't upgrade your BIOS, you may have problems
if you move the mouse while your computer is turning
suspend mode on or off.

View Software
Some utilities for Windows 3.1, such as Long File Names,
need to be upgraded or used differently with Windows 98.
To obtain a version of View Software that works with
Windows 98, call (800) 536-8439 in the United States.
Outside the United States, call (415) 856-8439.

MEMORY MANAGERS

If you have QEMM installed on your computer, it is
recommended that you remove it from your Config.sys
file before you set up Windows 98. You can add it
back after Windows 98 is installed.

The following memory managers are incompatible with
or may cause problems with Windows 98. It is
recommended that you remove all references to them
from your Config.sys and Autoexec.bat files and
useEmm386.exe and Himem.sys, which are provided
with Windows 98, to manage memory instead.

        Allemm4.sys - All Charge 386 Version 3.1
        HPemm386.sys and HPemm486.sys
        HPmm.sys - HP Memory Manager (must remove
            before Setup)
        Iemm.sys Memory Manager
        Intel(R) Expanded-Memory Emulator (Ilim386.sys)
        Maximizer Memory Manager (Maximize.com)
        NetRoom Memory Manager (RM386.sys)
        QMAPS Memory Manager Version 5.16
        UMB PRO Version 1.07

NOTE: The documentation for 386MAX recommends you not
set the EXT parameter below 64. If you set this parameter
to 0, Setup will fail.

NOTE: If you remove the line containing Rm386.sys from
your Config.sys file, you may need to install Himem.sys,
which comes with Windows or MS-DOS. You can do this by
adding the following line to your Config.sys file:

        device=<path>\himem.sys

The <path> is the location of your Windows or MS-DOS
files (for example, C:\Windows).


DISK-CACHE PROGRAMS

Before you run Setup, it is recommended that you remove
any third-party disk-cache programs and replace them
with Smartdrv.exe, which is provided with Windows 98.

If you are running one of the following disk-cache
utilities, remove it. In some cases, Setup will remove
it for you.

  386MAX Disk-Cache utility (Qcache.exe) (Do not use
      with SmartDrive.)
  Cache.exe Disk-Cache utility
  Cache.sys Disk-Cache utility
  Flash Disk-Cache utility (Flash.exe) (do not use
      with SmartDrive.)
  Hyperdisk Disk-Cache utility (do not use with
      SmartDrive.)
  Icache.sys Disk-Cache utility
  IBMcache.sys Disk-Cache utility
  Mace Disk-Cache Utility (Mcache.sys)
  Norton Speed Drive Disk utility (SPEEDRV)
  Norton Utilities Version 5.0 and 6.1 (DISKREET, NCACHE)
  PC-Cache (PC Tools disk cache utility) (must remove
       before Setup)
  PC-Kwik Disk-Cache utility (Pc-kwik.exe)
  PC_Kwik Disk Accelerator
  PC-Kwik Version 1.59 (Pck.exe, Pskscrn.exe, Pckey.com)
  PC Tools(TM) Disk-Cache utility (Pc-cache.com)
  Secretdisk II Disk-Cache utility (Fast512.sys) (Do not
       use with SmartDrive.)
  Super PC-Kwik Disk-Cache utility (Superpck.exe)

SETTING UP A DUAL-BOOT CONFIGURATION WITH WINDOWS NT

To set up a dual-boot configuration on an x86 computer,
install the operating system in the usual way, and then
edit the Boot.ini file as described below. All system
startup info is stored in the Boot.ini file, which is
automatically created during Setup at the root of your
computer's hard disk.

>>>To edit the Boot.ini file:

1. In Windows Explorer, click View, click Options, and
   then click "Show all files."

2. Make sure "Hide file extensions for known file types"
   is not checked, and then click OK.

3. Right-click the Boot.ini file, and then click Properties.

4. Click to clear the Read-only check box, and then
   click OK.

5. Right-click the Boot.ini file, click Copy, right-click
   a blank area of the Explorer dialog box, and then click
   Paste. A backup copy with the file name "Copy of
   Boot.ini" will be created.

6. Double-click the Boot.ini file.

7. Add the name and location of the alternate system in
   the [operating systems] section of the file, as in the
   following example:

 [operating systems]
 C:\Winnt="Windows NT 4.0"
 C:\="Microsoft Windows"

8. Save and close the Boot.ini file.

9. Right-click the Boot.ini file, and then click Properties.

10.Select the Read-only check box, and then click OK.

CREATING AN MS-DOS STARTUP PARTITION

To set up Windows 98, your startup drive must be an
MS-DOS startup partition. If your startup drive is
formatted as HPFS or NTFS, you must create an MS-DOS
startup partition before you run Setup. For more
information about creating an MS-DOS startup partition,
see your computer documentation.

USING TERMINATE-AND-STAY-RESIDENT (TSR) PROGRAMS
AND DRIVERS

APPEND (MS-DOS)
Do not use the APPEND utility with Windows 98. It
prevents Windows and Windows-based programs from
creating valid Well-Formed-Path (WFP) names for the
files they are using. (A WFP is the complete name of a
file, including the drive letter and full path
specification, starting from the root directory.)

Autocon Version 2.0e, Bootcon Version 1.60, and Boot.sys
These programs enable you to select from different
configurations when you start your computer. Because
Windows 98 Setup modifies only the first sections in
your Config.sys and Autoexec.bat files, you may have
to modify these files manually after Setup. For more
information, see the program documentation.

Cubit Version 3.01
When you are using Cubit with Windows 98, do not
compress the Windows System folder or any file that
is loaded from your Config.sys file.

Before you upgrade to Windows 98, make sure that the
earlier version of Windows is decompressed on your
hard disk. You may recompress the files after you
have successfully set up Windows 98.

Doubledisk Version 2.5
Windows 98 may try to access "phantom" disk drives if
you use it with Doubledisk. Phantom drives occur when
you use Doubledisk to create a compressed drive. For
example, if you have drives A, B, and C on your
computer and you use Doubledisk to create drive F,
Windows 98 and MS-DOS recognize drives D and E as valid
drives, even though they do not exist. You can use the
DRVOFF utility to prevent Windows from recognizing
phantom drives. To order a copy of the DRVOFF utility,
contact Vertisoft.

Infinite Disk Version 2.1
Infinite Disk version 2.1 does not work properly with
Windows 98. Either remove Infinite Disk software from
your computer before you run Setup, or contact your
software dealer for a version of Infinite Disk software
that is compatible with Windows 98.

>>>To remove Infinite Disk from your computer:

1. Decompress any compressed files.

2. Remove the following lines from your Config.sys
   and Autoexec.bat files:

 iddrv.sys
 idres.exe
 protect /c

3. Restart your computer, and then run Setup again.

NetWare(R) NetBIOS

In many configurations, the NetWare NetBIOS TSR is
incompatible with Windows 98. In most cases, Setup
will detect NetWare NetBIOS and remove the startup
command from your computer. However, if you have
NetWare NetBIOS set up to start from a location
other than your Autoexec.bat file (for example, from
a different batch file), Setup cannot detect it. In
this case, you need to remove NetWare NetBIOS manually.
Windows 98 includes an IPX/SPX-compatible protocol
that you can use instead of NetBIOS. For information
about configuring Windows 98 to work with it, see
Networks.txt.

Newspace Version 1.07
Windows 98 is incompatible with this disk-compression
utility.

Norton Desktop for Windows (Ep.exe)
If the data-recovery program Erase Protect (Ep.exe) is
loaded from your Autoexec.bat file, disable it when you
set up Windows, especially if you are upgrading over a
previous version of Windows. Because Erase Protect tries
to save copies of all deleted files, you can run out of
disk space while running Setup.

It is recommended that you run Erase Protect with a
permanent swap file. If you are using a temporary swap
file, exclude files that have a .tmp or .swp extension
from erase protection.

Norton Disklock Versions 3.01 and 3.5
Norton Disklock versions 3.01 and 3.5 do not work
correctly with Windows 98. Either remove this software
from your computer before you run Setup, or contact
Symantec product support for a version of Disklock that
is compatible with Windows 98.

For information about how to remove Disklock from your
computer, see the Norton Disklock documentation.

PC Tools Deluxe(TM) Version 7.1 (DATAMON)
If you load PC Tools DATAMON using the \SENTRY+ option,
Setup may fail if you are low on disk space. Do not use
the \SENTRY+ option when you are loading DATAMON.

Do not load DATAMON after loading SmartDrive. If DATAMON
is loaded after SmartDrive, your computer may fail. See
the PC Tools documentation for information about how to
remove DATAMON.

PC Tools Deluxe Version 6.0 (DESKTOP)
If you try to start PC Tools from the command prompt
within Windows, your computer may fail or restart itself.
These problems also occur if you use MS-DOS commands
from a command prompt within Windows.

Version 7.0 of PC Tools may correct these problems.
However, do not load DESKTOP from a command prompt if it
was loaded before you started Windows. If you do, your
computer may fail when you quit Windows. It is recommended
that you run DESKTOP from its PIF, provided with
Windows 98.

SUBST (MS-DOS)
You may encounter problems with SUBST during Setup, but
you can safely add it back after you have installed
Windows 98.

UNDELETE
If you are running UNDELETE with the SENTRY option, Setup
may have problems and you may run out of disk space during
Setup. It is recommended that you remove UNDELETE from
your Config.sys and Autoexec.bat files before running Setup.

NOTE: The SENTRY option creates a hidden directory named
Sentry. When you delete a file, UNDELETE moves the file
from its current location to the Sentry directory. Before
you remove UNDELETE from your Config.sys or Autoexec.bat
file, free disk space by using the UNDELETE/PURGE command
on all drives.

If you do not remove Undelete, Setup will disable this
command for you.

KNOWN POTENTIAL SETUP PROBLEMS

If you encounter problems during Setup, such as Setup
closing unexpectedly or error messages that do not apply,
increase the size of your permanent swap file. For Setup
to complete successfully, the size of your permanent swap
file plus the amount of RAM in your computer should equal
at least 14 MB. After you change your swap file size,
run Setup again.

NOTE: If your hard disk is compressed, you may have to
increase the size of your host drive before you can
increase the size of your swap file.


NOTE: Refer to the Intl.txt file to learn more about
installing Pan European settings.
