1. NEW TECHNICAL SUPPORT ADDRESS AND PHONE NUMBER
=================================================
If you still have questions after reading this file, call
Technical Support for assistance. Symantec's new technical
support address is:

               Symantec Corp.
               175 W. Broadway
               Eugene, OR 97401


In the United States and Canada, call:

     Technical Support:     503-465-8450
     Symantec BBS:          503-484-6669 (9600B)
                            503-484-6699 (2400B)
     Fax Support:           503-334-7470

To call from other areas, please refer to the Customer
Service Plan in the Norton Backup for Windows user guide.



2. INSTALLING WITH NORTON DESKTOP FOR WINDOWS
=============================================
If you have the Norton Desktop for Windows Scheduler installed,
Norton Backup for Windows will not create a Scheduler icon.
The Scheduler icon can be found in the Norton Desktop
Applications group instead of the Norton Backup group.



3. INSTALLING DOS 6.0 AFTER NORTON BACKUP FOR WINDOWS
=====================================================
DOS 6.0 installs an older version of the VFINTD.386 into the
DOS directory and then modifies the SYSTEM.INI
(DEVICE=C:\DOS\VFINTD.386). If you install MS-DOS 6.0 after
Norton Backup 3.0, the next time you launch Norton Backup you
will be sent a warning dialog. This dialog notifies you that
the VFINTD.386 is the incorrect version. If you click Ok in
this dialog Norton Backup will save the existing SYSTEM.INI as
SYSTEM.NBW and make the necessary change to the "Device=" line
in the SYSTEM.INI. You can also make the changes manually by
performing the following steps:

1. Open the SYSTEM.INI file using a text editor.
2. Search for the VFINTD line (DEVICE=C:\DOS\VFINTD.386).
3. Change the line to: DEVICE = [Nbwin install path]\VFINTD.386.



4. INSTALL DISK SPACE ESTIMATES
===============================
To insure that the user always has enough disk space to
install Norton Backup, the Install program displays the
maximum amount of space that may be required for installation.
This estimate is affected by the actual options selected
for install and also includes some space that is necessary
in order to run the install program.



5. CONSERVING DISK SPACE DURING INSTALLATION
============================================
To conserve disk space, Norton Backup for Windows 3.0 offers
the Custom install option. This option allows for installing
just the options that are needed thereby saving valuable disk
space. For example, Norton Backup supports several types of
tape drives, but if you will only be using a QIC-40/80 drive
there is no reason to install all of the other tape drivers
on your hard disk. Norton Backup allows you the option to
install all or some of the following:

          tape drive support
          Network Tape Sharing
          help files
          Norton Scheduler
          Norton Viewers



6. NORTON EMERGENCY RESTORE
===========================
The following tape drives and configurations are NOT supported
by Norton Emergency Restore:

     -IBM PS/2 model 40 used with the Archive 5240 tape
      drive as a B: drive

     -Colorado AB-10 adapter card used with a Colorado
      Jumbo 120 or DJ-10 tape drive that has a firmware
      version of 39 or earlier

     -SCSI and QIC-02 tape drives

     -IDE tape drives

     -Irwin AccuTrak tape drive series



7. COMPATIBILITY WITH NORTON BACKUP FOR DOS (VER. 1.2 & 2.2)
============================================================
If you are a user of Norton Backup for DOS and are currently
in the middle of a FULL/INCREMENTAL or FULL/DIFFERENTIAL
backup cycle, you should not have to interrupt that cycle and
start over. In fact, you should be able to use either product
to create your next backup volume.

Symantec strongly recommends however, that you confirm you'll
be able to do this by first using Norton Backup for Windows to
restore some files that were backed up with Norton Backup 1.2,
2.0, or 2.2 for DOS. If you encounter any errors while restoring,
there may be some limitation(s) --either hardware or
software--that inhibits compatibility with older Norton Backup
volumes. If this is the case, you should start the cycle
over by making a full backup of all your drives before resuming
your routine.


7.1 Setup Files
---------------
If you are planning on using the same Setup files for both
Norton Backup for DOS and Norton Backup for Windows, use
include and exclude statements to describe file selections.
Manual file selections made in the Windows product cannot be
read by the DOS product.


7.2 Data Verification
---------------------
If data verification in your setup file was set to "Read Only"
in Norton Backup for DOS (Ver. 1.0 and 1.2), be sure to check
your settings in Norton Backup for Windows when you first load 
that setup file. The "Read Only" option does not exist in
Norton Backup for Windows and the setting will default to
"Read and Compare" or "Compare After Backup."  Change this
setting if you prefer a different option.


7.3 Macro Compatibility
-----------------------
If you plan to use setup files that were created with Norton
Backup for DOS, you will need to re-create any macros that were
associated with those setup files.



8. CONFIGURING SCSI DEVICES
===========================

8.1 Resolving Configuration Problems
------------------------------------
If you are having trouble configuring your SCSI drive, try
the following:

  1. Make sure that the drive supports the tape being used.
  2. Make sure the chain is properly terminated (if using
     only one device, it must be terminated).
  3. Make sure the terminators are not plugged in backwards.
  4. If an external device is the last device in the chain,
     make sure that it is powered on (in order for the
     terminators to be effective).
  5. Try turning off sync negotiation.
  6. Try turning off parity.
  7. Try turning off disconnect.
  8. Make sure 1-3 devices (including the adapter) are supplying
     termination power.
  9. Remove all but 1 device from the chain.
 10. Minimize cable length (1 foot).
 11. Remove disk cache programs.
 12. Verify that each SCSI device on the chain is set to a
     unique SCSI ID.


8.2 Hanging When Searching for Devices
--------------------------------------
If your system hangs while searching for SCSI devices, it
may be due to an address conflict with the SCSI host
adapter or a SCSI ID conflict. Verify the addresses or SCSI
ID's being used and try again.


8.3 Multiple SCSI Adapters
--------------------------
If you are using a Future Domain driver and also have
a path to WINASPI.DLL, strange characters may be
displayed on the screen when using Norton Backup for Windows. 
To solve this you can either temporarily rename or delete
the WINASPI.DLL file.


8.4 PS/2 Model 30/Mountain Mach II Card
---------------------------------------
Using the default address settings on the Mountain Mach II
card in a PS/2 Model 30 will cause the system to lock up.
The default DMA setting on the high-speed controller and
the hard drive are both 3. Change the DMA setting on the 
card before configuring with Norton Backup.



9. NETWORKS/NETWARE BINDERY
===========================

9.1 Maximum Path Size Supported
-------------------------------
Currently, Norton Backup does not support paths that are
greater than 63 characters.


9.2 Restoring NetWare Bindery
-----------------------------
After restoring netware bindery to a server, it is a good
idea to run BINDFIX from the server. Use the BINDFIX 
command at the SYS:SYSTEM prompt to update the bindery with
any user changes that may have occurred since the backup. 
For more information, refer to the Novell NetWare Utilities
Reference manual.


9.3 Trustee Information
-----------------------
Trustee information cannot be restored if you select a Restore
To option other than Original Location.



10. NETWORK TAPE SHARING
========================
The minimum requirements to run Share are: IPX 3.10 or
IPXODI 1.2. It is recommended that you use IPXODI. If you
experience network connection losses or timeout errors during
a share session, verify that the versions of IPX and Net Shell
are correct.


10.1 Share Retries
------------------
For networks with heavy traffic, the "Share Retries" setting
can be added to the NDW.INI file. This will allow you to
adjust the number of times Norton Backup will attempt to share
a device. By default, Norton Backup will attempt to share the
device every half a second, 220 times.  This setting can be
adjusted according to your network's traffic.

To add this setting to the NDW.INI file:

     1. Open the NDW.INI file using a text editor.
     2. Search for the [NBACKUP] section.
     3. Add the following line to the end of the
        [NBACKUP] section:

     share retries = x (where x represents the desired value).


10.2 Windows Standard Mode
--------------------------
Currently, when running in Windows Standard mode there may
be problems allocating enough memory to use the Share
feature. Attempting to share can cause the "Unable to create
DMA buffers" message and Norton Backup will quit on machines
with 2 to 4 Mb of installed memory.



11. FLOPPY DRIVES AND DOS PATH
==============================

11.1 Using a 360Kb Diskette in a 1.2Mb Drive
--------------------------------------------
Performing backups to 360Kb diskettes in a 1.2Mb floppy
drive is not recommended, and will almost surely result in
lost data when attempting to restore.  However, Norton Backup
for Windows does support backups to 360Kb diskettes in 1.2Mb
floppy drives in order to allow file transfer between older
and newer computers.  The best method to do this is to format
the diskettes in the 360Kb drive, then back up using the
"DOS Path" option in the Backup To combo box, and the 360Kb
component size setting in the backup options (General category).
Even when this procedure is used, these diskettes should not be
relied upon as the sole backup of a hard disk.


11.2 Floppy Drive Contention
----------------------------
Norton Backup for Windows allows you to switch to other
applications while backing up or restoring data. To insure
that access to the floppy drives or tape drive is not
interrupted during this process, Norton Backup hides these
drives from all other applications.  Programs that display a
list of available drives may not display drives A: and B:
during these background operations.  For the same reason, you
should not try to access your floppy drives directly.  For
example, typing FORMAT A: in a DOS window while using Norton
Backup to back up to a floppy drive will produce an
"invalid drive specification" or "drive not ready" system
message. Normal use of the drive will return once the backup
is finished.

Note that this is also true when using a QIC 40/80 or
AccuTrak tape drive that is connected to the floppy
controller as a B: drive. When using high-speed controllers
or adapters with a QIC-40/80, AccuTrak, IDE, or QIC-02
drive, you will be prevented from using the floppy drives
only if the controller card is using DMA 2 or IRQ 6
(sharing the same addresses as the Floppy diskettes).

When using SCSI tape drives, floppy drive access is
not restricted.


11.3 Data Verification vs. Compare Function
-------------------------------------------
To safeguard your data you should take the time to check
that the data written to your diskettes matches the data
on your hard disk. You can do this through Data Verification
while the backup is in progress, or by using the Compare
function after the backup is completed.

Data verification during a floppy or DOS Path backup verifies
the reliability of the media more than the data itself. For
this reason, it is safest to also perform a Compare after
the backup (using the Compare function) which will verify that
the compressed form of the original data was not corrupted
when transferred into memory.


11.4 Compare Function
---------------------
Compare is a separate function designed to provide maximum
data security.  The data in the backup set is compared to the
source data on the hard disk using the following procedure:

1. Reads the data on your backup medium exactly as if it were
   going to restore the data to the hard disk.

2. Compares this data to the data found on the hard disk.

3. Verifies that the files are identical and displays a
   message if they do not match.

Wangtek, Inc.     5150PK, MK, EQ       Wangtek QIC-02 Adapter


12.3 Adaptec WINASPI and DOSASPI Drivers
----------------------------------------
The SCSI drivers, Adaptec's WINASPI and DOSASPI, are not
automatically installed. You can install them using the
supplemental or custom install feature. The benefits of
using WINASPI are the ability to run multiple DOS boxes 
and increased performance.


12.4 SCSI Wangtek 6130/Adaptec 1520 or 1542C card
-------------------------------------------------
The Wangtek 6130 tape drive and an Adaptec 1520 or 1542C
card are not supported configurations.


12.5 SCSI Security Erase
------------------------
Security Erase on some SCSI tape drives may take as long as
6 hours.


12.6 Incompatible Tape Cartridges
---------------------------------
Using tapes that are incompatible with the drive can cause
your system to "hang." Reboot your system and verify that
you are using a tape cartridge that is compatible with your
drive.


12.7 Low Capacity DC6000 Tape Cartridges (250 Mb or less)
---------------------------------------------------------
At this time, backups made with low capacity DC6000 tape
cartridges (250 Mb or less) can only be restored with Norton
Backup. If you plan on restoring a backup set made by Norton
Backup with another vendor's software, use high
capacity tapes (320 Mb or greater) to make the backup.


12.8 SCSI - Tapes Used With Other Backup Software
-------------------------------------------------
Tapes that have been used with other backup software
may cause unexpected behavior when used in Norton Backup.
Initializing these tapes with Norton Backup will solve
the problem.

To Initialize a tape:

     1. Insert the tape in the SCSI device.
     2. Select Initialize from the Tape Tools menu.
          
Note: If you experience this problem during the compatibility
test, initialize the tape and rerun the test.



12.9 SCSI Chain Termination
---------------------------
If you experience unusual problems during tape operations,
insure that the SCSI chain is properly terminated. 
Please refer to your SCSI device installation manual 
for more details.


12.10 Manual Add - SCSI
----------------------
You cannot manually add a SCSI or InfoServer device in
Norton Backup. The Manual Add feature, when used for 
SCSI and InfoServer, is for troubleshooting purposes
only. However, this feature will display the number of
SCSI and InfoServer drives and/or errors detected.


12.11 QIC-02 Maynard Controllers and Drives
-------------------------------------------
At this time, Norton Backup does not support Maynard
controller cards or drives.


12.12 Hardware Compression
--------------------------
If your SCSI tape drive has hardware compression and Norton
Backup does not detect it, insure that the hardware compression
switch on the tape drive itself is on.

Hardware compression can be turned on and off from the Hardware
Compression checkbox in the Settings dialog (Configure window).
To change the compression setting:

     1. Click the Configure button.
     2. Select the desired SCSI device.
     3. Select the Settings command... button.
     4. Set the Hardware Compression checkbox to the
        desired setting.

Note: When hardware compression is turned on, software
compression alternatives will not available in the Backup
General options window.


12.13 SCSI Device Troubleshooting
---------------------------------
If your SCSI device light begins to flashes or if Norton
Backup starts to hang during tape operations, it's possible
that the device needs to be cleaned. Please refer to
the users manual for information on the device's flash
codes and cleaning recommendations.



13. QIC-40/80 and IDE TAPE DEVICES

13.4 Colorado TC-15 Hardware Compression
----------------------------------------
Hardware compression can be turned on and off from the
Compression drop-down list box in the Settings dialog
(Configure window). To change the compression setting:

     1. Click the Configure button.
     2. Select the QIC-80 device.
     3. Select the Settings command... button.
     4. Select the desired setting in the Compression
        drop-down list box.

Note: When hardware compression is turned on, software
compression alternatives will not available in the Backup
General options window.


13.5 Troubleshooting High-Speed Controllers
-------------------------------------------
To properly set up your system, you should avoid using an
interrupt request (IRQ) that is used by another device 
(i.e., mouse, sound card, network card, scanner, etc.).
Some common IRQs that may already be used in your 
system include:

    IRQ 3     COM 2-4 ports
    IRQ 4     COM 1 port

Symptoms of an IRQ conflict include Norton Backup not
finding the tape controller and network problems when
backing up to tape.


13.6 Video/DMA Conflict Problems
--------------------------------
Norton Backup uses direct memory access (DMA) channels to
read and write data. Sometimes using a tape device that is
connected to the floppy controller causes conflicts with
the Windows 3.1 video drivers.

During the compatibility test, Norton Backup determines if
your system has a video/DMA conflict and if so, goes through
a series of tests in an effort to ensure your system runs
reliably with Norton Backup. After each test a message will
inform you that tests are still being performed. If Norton
Backup has attempted every test and your system will still not
work reliably, a message will inform you of the problem.

NOTE: If you experience video/DMA conflicts, try disabling the
Video Caching option (sometimes referred to as Video Shadowing)
in your CMOS setup.


13.7 Hard Drive Cable Support - IDE
-----------------------------------
Operating an IDE drive on the same cable as the hard drive is
supported in Windows Standard mode only.


14. ACCUTRAK TAPE DRIVES
========================

14.1 Supported AccuTrak Tape Drives
-----------------------------------
This section lists the AccuTrak tape drives that are supported
by Norton Backup. AccuTrak drives require pre-formatted tapes.


MANUFACTURER               MODEL NAME
-------------------------------------------------
Irwin Magnetic Systems     A120, 2040
Irwin Magnetic Systems     A250, 2080
Irwin Magnetic Systems     A250xxST, 2120



15. INFOSERVER
===============
Backups created on InfoServer tapes are only readable on
InfoServer tape drives. InfoServer tape drives cannot read
a backup made by a drive not connected to an InfoServer.



16. WINDOWS STANDARD MODE
=========================

16.1 Using DOS Boxes
--------------------
Shelling out to DOS under Windows Standard mode is not 
supported when using Share, a SCSI, IDE, or InfoServer 
tape device.


16.2 NDW 2.0
------------
If you are running Norton Desktop for Windows 2.0 in Standard
mode, you may experience memory errors when trying to launch
Norton Backup. Loading the Program Manager as the shell should
resolve the problem.



17. SYSTEM FONT
================

17.1 Sharing Violation
----------------------
If you have SHARE.EXE loaded, you may receive a sharing
violation on the file "Arial.ttf" during backups. Because
the file is being used by the system, it is open at the time
Norton Backup is trying to back it up. Skip this file and 
continue with the backup.



18. CORRECTABLE ERRORS
======================
If you are getting excessive correctable errors during
compare or restore, check the following:

     1. Make sure that the drive is grounded.
     2. Make sure that the drive is clean.
     3. Make sure that your "Buffers=" statement in your
        config.sys is set to 30 or greater.
     4. After you've retrieved the data from the tape,
        use Tape Tools Format or [SCSI/QIC-02] Tape Tools
        Erase. OR, use a newer tape.

Norton Backup recommends that the "Buffers=" statement be set
to 30 or greater even if using a disk caching program. A low
buffer statement may lead to excessive correctable errors and
thus directly affect the performance of your backup or restore.

Note: If the number of errors corrected is more than the errors
found, make sure that the Burst Mode setting is off. To change
the Burst Mode setting:

     1. Click the Configure button.
     2. Select the QIC-80 or AccuTrak device.
     3. Select the Settings... command button.
     4. If active, click the Burst Mode checkbox to
        turn the option off.


18.1 How Many Correctable Errors are Acceptable?
------------------------------------------------
It is acceptable to have up to 50 correctable errors on a full
tape. If you have tried all the steps in section 18 above, but
are still exceeding 50 errors, contact technical support.



19. COMPRESSED DRIVES
=====================
If you are using compression software such as Stacker or
DoubleSpace, do not back up the compressed file (for example,
stacvol.* or the dblspace files), back up the logical drive
instead. Because these compressed files are typically very
large, attempting to restore may cause problems if you do not
have enough disk space to restore the compressed file.



20. HARDWARE/SOFTWARE INCOMPATIBILITIES
=======================================

20.1 Notebook Power Management Feature
--------------------------------------
Running some notebook computers with the power management
option on may cause problems when using Norton Backup. To 
avoid power loss during backup operations, disable the power
management option:

Zenith - Set the Floppy Disk Drive Power Management option
      to "Full Auto."

Gateway - Run SETPOWER /LO.

Texas Instruments - Run SETPOWER /LO.

If you experience problems with another brand of
notebook computer, see the users guide for information
on disabling the power management option.


20.2 Alloy Retriever 40/60/60e, and 250cs
-----------------------------------------
Some problems exist between older firmware and Norton Backup.


20.3 COREtape Light QIC 80
--------------------------
Some Core International software versions may not be compatible
with  Norton Backup. Verify that you can restore backups made
with Core International software using Norton Backup.  You may
want to keep the Core International software on your computer
in case you need to restore old backups made with that software.


20.4 Iomega AccuTrak Read Mode
------------------------------
Norton Backup does not support reading AccuTrak tapes in
the Iomega 250 QIC 40/80 tape drive at this time.


20.5 Maynard ArchiveXL 5240 (XT only), 5540, 5540e, 5580,
5580e, and 3580 (PS/2)
----------------------------------------------------------
Some 5240 drives have hardware incompatibilities.
Norton Backup only supports tape drives with serial numbers
starting with BB or above.  Serial numbers starting with AA
or AB are not supported.



21. LIMITATIONS
===============

21.1 Special Characters in Passwords
------------------------------------
You can use characters typed directly from the keyboard for
passwords.  If doing floppy, DOS Path, QIC 40-80, AccuTrak,
or IDE backups, do NOT enter characters in your password by
holding the Alt key and typing a three-digit number on the
numeric keypad. If you use these special characters in a
password, you must use the Emergency DOS Restore Disk or
Norton Backup for DOS to restore your backup set.


21.2 Logging Drives
-------------------
If you receive a message that Norton Backup for Windows
cannot log a drive because it contains too many directories,
you can work around this problem as described below.

If the drive is a local drive (as opposed to a network drive,
use the DOS SUBST command to map the directory you want to
back up to a new drive letter.  For example, to substitute
the drive letter F: for the directory E:\SOFTWARE\DOS, type:

       SUBST F: E:\SOFTWARE\DOS

If the large drive is a Novell NetWare file server, use the MAP
command with the ROOT option to map a drive letter to a
sub directory on the volume.  For example, to map the drive
letter G: to a network directory called SERVERA\VOLUME1\PATHNAME,
type:

       MAP ROOT G:=SERVERA\VOLUME1:\PATHNAME


If you experience problems using the MAP ROOT command, see
your Novell documentation. If you receive a message that
Norton Backup for Windows cannot log a drive because it 
contains too many files in a single directory, the only 
work around is to reduce the number of files by moving 
them to another directory if possible.
