Norton Desktop for DOS Version 1.00
5/26/92
This file contains compatibility information, late-breaking
news, and feature updates which do not appear in the manual.
Welcome to the NORTON DESKTOP FOR DOS!
The Norton Desktop for DOS requires DOS version 3.1 or later and a hard
drive with at least 3.2 megabytes free. A full installation of the
Norton Desktop requires 8 megabytes of disk space. The Norton Desktop
requires 640k RAM with at least 512k free, but will benefit from 1 meg
or more of EMS and/or XMS memory. You must have an additional 2mb of
free disk space in order to run the Norton Desktop for DOS.
For those who are not familiar with Windows like programs, please take a
few moments and use the Guided Tour. The tour comes up automatically
the first time you use the Norton Desktop. Thereafter, it can be run
from the Help menu on the Norton Desktop. Even for experienced users it
contains a number of tips that will make the use of the Norton Desktop
even easier.
This document is divided into four sections. The first covers general
compatibility information. The other three sections are in separate
files. README.ND discusses the Norton Desktop itself, including
corrections and additions to the manuals. README.NAV discusses issues
specific to the AntiVirus program, including what to do if a virus is
detected during installation. README.NB discusses the Norton Backup
program including the latest information on tape drive compatibility.
Any of these files may be printed from the desktop by pulling down the
file menu and selecting print.

GENERAL COMPATIBILITY INFORMATION
***** BACKUP PROGRAMS *****
See the file README.NB for tape drive compatibility information and
other tips on using Norton Backup.
You should disable the screen saver prior to running any backup program.
Backup programs (including the Norton Backup) require special setup when
the Norton AntiVirus is loaded. Norton AntiVirus prevents any program
from accessing NAV_.SYS when it is active in memory.
Solution #1:
Add NAV_.SYS to the Copy Protected Files list found in the Special box
in the Select Files screen. This will tell Norton Backup not to
attempt to backup these files. Other backup programs usually have a
similar feature. In the event you need to restore NAV_.SYS or NAV&.SYS
you can do so from the original Norton AntiVirus disks. The benefits
from this solution are that unattended backups are possible, Norton
AntiVirus is active, and you do not need to remember to disable Norton
AntiVirus.
Solution #2:
To temporarily disable Norton AntiVirus, reboot the computer, press and
hold down the two SHIFT keys after you hear the first beep from the
computer. A message should display stating that Norton AntiVirus has
not been loaded. You may now release the keys and make your backup.
Remember to reboot again to reactivate Norton AntiVirus. The benefit of
this solution is that you have a backup that contains all of the Norton
AntiVirus files that were selected for backup.
Running a backup program while Virus Intercept is running in Detect
Unknown Viruses mode with Auto-Inoculate OFF may cause an alert as you
back up any non-inoculated files. The backup program will stop and wait
for a response to the alert screen. Because some backup programs cannot
tolerate an unexpected interruption, they may abort.
***** COMMUNICATIONS PROGRAMS *****
For maximum protection, Virus Intercept alerts halt all other system
activity. Consequently, time-sensitive communications programs, such as
ProComm Plus or Crosstalk, may crash or lose data after an alert is
displayed. Because NAV_.SYS scans only reads from disk, this is likely
to happen only if you are multitasking or if you are uploading an
infected file to someone else.
***** NORTON PC ANYWHERE *****
In order for the screen saver on the host to be interrupted by
communications, PC ANYWHERE must be set up correctly and NSCHED must be
loaded AFTER PC ANYWHERE.
The Host must be setup as follows:
Host Operation
- Host Preferences
- Features
- Special Keyboard Handler Type
- TYPE 1 or 2 if the machine is IBM.
NOTE: If the Host is running QEMM and it is in Stealth mode then XST=F000
must be added to the end of the QEMM386 command line.
Remote Operation
- Remote Preferences
- Remote Access Session
- Special Keyboard handler
- Type 1
If Virus Intercept is running on the host computer and an alert appears,
the alert is not heard at the remote location. However, if the alert is
displayed for longer than a few seconds, it will be displayed at the
remote location.
***** COMPRESSED DRIVES (STACKER, SUPERSTOR, ETC) *****
Do not place temporary or swap files on your compressed drive. To
prevent this, create a TEMP environment variable and set it to the
uncompressed portion of your drive (or to a RAMDisk).
You must disable the virus intercept before installing disk compression
software. See the general compatibility notes for Backup for the steps
to follow.
If Norton Desktop is loaded onto a compressed drive, the device driver
statement(s) for the compression software MUST appear in your CONFIG.SYS
file ABOVE any device driver statement that loads programs from the
Norton Desktop.
Due to a limitations in most compressed software drivers, if you are
mixing compressed volumes and uncompressed volumes on the same cartridge
of a removable drive (such as those made by Syquest or Bernoulli),
Norton AntiVirus will not be able to scan the non-compressed portion of
the removable drive. Files on the compressed volume, however, will be
scanned normally.
Back up the compressed drive instead of the envelope file (STACVOL.xxx
or SSPARTSS.SWP). If you backup just the envelope file then you will
NOT be able to restore a particular file from your compressed drive. You
will be forced to restore the whole drive. If you lose or damage one
disk containing this huge file then you will lose all the data that was
on your compressed drive.
DO NOT attempt to use Speedisk on a compressed drive! Speedisk will not
allow you to optimize a Stacker or SuperStor drive. Use the
de-fragmentation utility provided by the maker of the compression
software.
For Information on using the Norton Cache with compressed drives, please
refer to the Norton Cache section of README.ND.
***** DISK OPTIMIZERS AND DISK REPAIR UTILITIES *****
Do not run any disk optimizer programs (other than Speedisk) or any disk
repair utilities (other than the Norton Disk Doctor) from within the
Norton Desktop. You must completely exit the desktop (Alt+F X) in order
to safely run other utility programs.
***** ERASE PROTECT and FILE SAVE *****
SMARTCAN replaces both of these programs. Users who purchase Norton
Utilities V5.0 and 6.0x or the Norton Desktop for Windows V1.0 should
use SMARTCAN instead of EP. SMARTCAN offers support for a larger
variety of networks.
To purge files from your old TRASHCAN directory, use EP or FILESAVE.
UNERASE will search both TRASHCAN and SMARTCAN directories when
searching for erased files.
***** IOMEGA DRIVES *****
NCACHE is compatible with IOMEGA removable disk drives only when using
Version 7.0 or later of the RCD.SYS device driver. This version of the
driver is compatible with all types of IOMEGA disk drives, and both ISA
and MicroChannel computers. Please contact IOMEGA for an upgrade if you
are using an earlier version.
***** MEMORY MANAGERS *****
If you use a 386 memory manager and are experiencing problems running
the Norton Desktop, you may need to add the following commands to your
AUTOEXEC.BAT file:
SET RTVMEXT=0
SET RTOVEXT=0
***** LOADING TSRs AND DEVICE DRIVERS HIGH ******
With the exception of NAV&.SYS and NAV_SYS, all TSRs and device drivers
supplied with the Norton Desktop are able to load themselves high
without a LOADHIGH or DEVICEHIGH statement. If you are using DOS 5's
memory managers, you must load both HIMEM.SYS and EMM386.EXE (with the
RAM or NOEMS option) and have the statement DOS=UMB or DOS=HIGH,UMB in
your CONFIG.SYS file in order to load anything high.
This ability to load high will cause problems for programs such as
Qualitas' Maximize and Quarterdeck's Optimize. Two solutions to the
problem are possible. The first is to remark out all Norton TSRs before
running the optimization program, then remove the remarks once
optimization is completed. The second solution is to use the /SKIPHIGH
parameter on all Norton TSRs. This will keep the TSRs from loading
themselves high an allow the memory manager to do the work. Do not use
the second approach with NCACHE.
***** QEMM & 386^MAX *****
When using the NAV&.SYS or NAV&.SYS /B Virus Intercept drivers with QEMM
or 386^MAX memory managers, you may experience a "batch file missing"
error when calling a secondary batch file from within your AUTOEXEC.BAT.
This is the result of special actions that Virus Intercept must take
when a LOADHI command is executed.
This circumstance can be prevented by executing any program or external
DOS command (other than LOADHI) immediately prior to calling the
secondary batch file.
You may get a message from QEMM to "set DMA=xx" where xx is a number.
Just follow QEMM's instructions for adding this to the QEMM device line
in the CONFIG.SYS. QEMM needs this line to handle Norton Backup's use
of the DMA channels.
***** QEMM STEALTH MODE *****
Users who have enabled QEMM's STEALTH mode must ensure that QEMM appears
in their CONFIG.SYS file before any of the Norton Desktop device
drivers.
The Copy Disk command may have problems on some systems if Stealth is
used. QEMM will issue an error message, usually indicating that you
need to add the command DBF=2 to your QEMM command line. Add the
command indicated by QEMM and Copy Disk will then function normally. As
an alternative, you can run ND using the /NOFRAME parameter.
***** MOUSE *****
The Norton Desktop for DOS supports most popular mice and other pointing
devices that emulate a Microsoft Mouse. You must install the mouse
driver software provided by the mouse manufacturer before the Norton
Desktop will recognize the mouse.
If you are using a Genius mouse, you will need the mouse driver V9.XX or
later to use the Norton Desktop. Contact KYE International for an
update.
If you have a Packard Bell computer and get a "Divide Overflow" message
when starting any of the programs from the Norton Desktop package, you
will need to get an updated mouse driver from Packard Bell. Until you
receive the updated driver, you will need to REM the line in your
AUTOEXEC.BAT or CONFIG.SYS that loads the mouse.
If you get a mouse cursor on the screen but it doesn't move when you
move the mouse, go into the Desktop Configuration menu and select video
and mouse. Remove the checkmark from the Fast Mouse Reset box by using
the spacebar, then save the configuration. The mouse should now
function properly.
***** NETWORKS *****
***** BANYAN VINES *****
The Norton Desktop for DOS supports Banyan VINES version 4.x. For full
support of the network features provided in the Norton Desktop for DOS,
you must have NetBIOS service installed and running on the network
server. By default, Banyan does not install NetBIOS support. The
system administrator should run PCCONFIG and select the NetBIOS support
option. Please refer to the Banyan manuals for details of how to select
this option on your server.
***** LAN MANAGER *****
The Norton Desktop for DOS supports LAN Manager version 2.x. In order to
use the Network Link feature with Microsoft LAN Manager, you must add
the following lines to the [NETBEUI_XIF] section in the PROTOCOL.INI
file, unless you already have entries with higher values:
NCBS = 20
SESSIONS = 5
These changes must be made every time you run the workstation
configuration program SETUP.EXE, since it removes these lines.
***** LANTASTIC *****
The Norton Desktop for DOS fully supports Lantastic version 4.x.
However, because Lantastic can share the drives on your local computer
with other network users, you will get messages from several programs
within the Norton Desktop for DOS informing you that they cannot perform
the requested operation when the network is loaded. To run these
programs, reboot your machine without loading the network then run the
desired program or desktop function. Programs that need to be run
without the network loaded are: DiskTools, Image, Norton Disk Doctor,
Safe Format (only if making a system disk), and UnFormat. If SMARTCAN
was not loaded and protecting a shared drive, UnErase must also be run
without the network loaded to unerase files on that drive.
Lantastic users should add the parameter /TIMEOUT=1 to the command line
for the AILANBIO driver.
***** NOVELL NETWARE AND NETWARE LITE *****
If you are using the ODI drivers for Netware or Netware Lite, you must
use version 1.13 or later. Contact Novell for update information.
Users who own Microsoft Windows 3.1 can get the updated ODI driver from
their Windows installation disks.
Network link on a Novell Netware network will only function correctly on
connection numbers below 256. To see what connection number a
workstation is connected to, use the Novell WHOAMI command.
***** OPERATING ENVIRONMENTS *****
***** DESQVIEW *****
Use NAV_.SYS as the virus intercept when using DESQview. NAV&.SYS does
not detect program executions under a multitasking environment. In
addition, do not run Virus Clinic in the background under DESQview, as
viruses may not be properly identified.
If you run Norton Desktop for DOS under DESQView, you may want to add
the /USEINT16 option to your ND command line. This will allow DESQView
to capture keyboard commands correctly.
Norton Backup users should refer to the Software Tips section in the
README.NB file for additional information.
***** DRDOS 6.0 *****
In general, the Norton Desktop for DOS is compatible with DR DOS
versions 5.0 and 6.0. One exception is that DR DOS's password
protection of files and directories is not supported. Please note that
some of the utility programs supplied with DR DOS should not be used as
they may conflict with similar programs that are part of the Norton
Desktop for DOS. As an example, the DELWATCH utility should be replaced
with the Norton SmartCan. In all cases, the programs supplied with the
Norton Desktop offer better performance and/or more reliable data
recovery.
International users that switch code pages may find that they cannot
access some of their files because one or more characters that make up
the name are invalid in the current code page. This affects only those
functions that allow the user to input the file name.
If you are using DRDOS with any memory manager other than EMM386, you
may experience problems if DRDOS is using all or part of the HMA. The
problem will be immediately obvious as ND will hang when you attempt to
run it. To avoid this problem, always run ND with the /NOHMA option.
***** DOS 5 SHELL *****
When running Norton Desktop for DOS under DOSSHELL you need to add the
following statement to your AUTOEXEC.BAT:
SET RTVMEXP=0
You also must run ND with the following command line:
ND /NOUMB /NOFRAME
***** NDOS and 4DOS *****
The Norton Make Disk Bootable and Safe Format programs need to have a
copy of DOS's COMMAND.COM on the path in order to function correctly.
The Advanced Option to always update the master environment is not
available when using NDOS or 4DOS.
***** MICROSOFT WINDOWS *****
All the TSRs and device drivers in the Norton Desktop for DOS are
compatible with Windows 3.1.
When running the Norton Desktop for DOS under Windows, you may need to
turn Fast Mouse Reset off in order for your mouse to function correctly.
See the MOUSE section above for details.
Each of the three Virus Intercept device drivers included in The Norton
AntiVirus operates with Microsoft Windows. When running Windows, you
will not see a Virus Alert message on the screen when a virus is
detected. You will, however, hear the audible alarm, regardless of
whether the Special Sound option is set on or off.
If you run Windows in standard mode and have 1 Megabyte or less RAM use
NAV&.SYS /B as the device driver for best results.
When is pressed to "warm boot" your system, Virus
Intercept checks the boot sector of any diskette in your bootable floppy
disk drive. This feature does function under Windows. However, for the
highest level of protection, it is recommended that you exit Windows
prior to rebooting.
If you select "Detect Unknown Viruses" from the "Options - Global" menu,
you MUST scan your Windows directories with the "Auto Inoculate" option
turned on, prior to reentering Windows. If "Auto Inoculate" is turned
off and Windows is started without being inoculated, your system may
hang.
With SHARE.EXE loaded, a number of files will report "Access denied"
during a scan. This is because these files are exclusively locked by
Windows, and/or possibly some other application. These files may be
scanned by exiting from Windows and scanning with the Virus Clinic.
Use the NBACKUP.PIF file when running the Norton Backup for DOS under
Windows.
The scheduler and screen blanker are disabled while Windows is running.
If you have problems with the desktop while within Windows, try adding
the following statements to your AUTOEXEC.BAT file:
SET RTVMEXP=0
SET RTOVEXP=0
For tips on using the Norton Cache with Windows, please refer to the
Norton Cache section in the README.ND file.
***** TANDY 1000 *****
The Norton AntiVirus portion of the Norton Desktop will not run on Tandy
1000 series machines. All other parts of the Desktop should function
properly.
***** VIDEO COMPATIBILITY *****
Some EGA and VGA adapters have a quirk which causes screen degradation
problems when the graphical (arrow-shaped) mouse pointer is used. In
some cases, disabling the hardware mouse cursor on the video card will
clear up the problem. If small dots appear and disappear as the mouse
is moved, you should use the standard mouse pointer. Choose the Video
and Mouse Options item from the Norton program's Configure menu, and set
the Graphics Options to either "Standard" or "Graphical Controls." If
you have trouble reading the program's screens in order to change this
option, type "MODE CO80" at the DOS command line to fix the display,
then type "NDCONFIG /G0" to start the configuration program in the
standard mode.
***** HERCULES GRAPHICS CARD USERS *****
If you are using the NAV_.SYS Virus Intercept driver and a Hercules
graphics card which does not contain a light pen port, you may
experience a system lockup if a Virus Intercept Alert appears while your
system is running a graphics-mode application (such as Windows). To
prevent this, turn off the visual alert feature of the virus intercept
before running Windows or other graphics programs.
In order to use the graphics viewers, you must load the program MSHERC
before starting the Norton Desktop.
***** IBM XGA *****
Some IBM XGA controllers have a problem displaying the graphical mouse
cursor. The cursor is properly shown when it is at rest, but any
movement causes the area around the cursor to show garbage while the
cursor is in motion. This is the result of an incompatibility between
the XGA hardware and VGA hardware. The solution is to disable the
graphical mouse cursor (from the Configure Video/Mouse option in ND or
NDCONFIG).
***** LAPTOP COMPUTERS *****
Some laptop computers have an option to select whether their LCD display
is fully VGA compatible or "looks better." Most of the laptops that
have this option come from the factory set up to "look better." The
Norton Desktop for DOS can't display the graphical mouse cursor or other
graphic font enhancements on a non-standard LCD display. You must
either configure the LCD to be VGA compatible or configure Norton
Desktop for "Standard" video using the NDCONFIG program.
***** ULTRAVISION *****
All programs in the Norton Desktop for DOS with the exception of the
Norton Backup support Personic's Ultravision. With many VGA video cards
and a Multi-frequency monitor, the display area can be increased to as
much as 132 by 36 and still keep the graphical mouse and graphical
displays. If you are willing to sacrifice the graphical displays, a
desktop area as large as 132 by 63 is possible. These larger desktop
sizes allow for more and/or larger windows which can really enhance the
usability of Norton Desktop for DOS.
Since Norton Desktop for DOS senses UltraVision, it will always restore
the screen to the original UV starting mode when returning to the
desktop from an external program. Therefore, the desired UV mode must
be set before starting Norton Desktop and cannot be changed from within
the desktop.
To run programs that require a different mode, create a NMenu Batch
containing the line "UV x" and then the program. For example,
QA.COM from Symantec requires 80x25, so the NMenu Batch would have the
following 2 lines:
UV 80x25
QA.COM
UV 108x36
Note that NMENU does not reset the screen mode when a program exits
unless ND is running.
