+ WIN95.TXT - Installation instructions for Windows 95 +
++++++++++++++++++++++++++++++++++++++++++++++++++++++++


++++++++++++++++++++++++++
+ AUTOMATIC INSTALLATION +
++++++++++++++++++++++++++

For Windows 95 installation:

        Start|Run|A:\SETUP
        
        Or launch A:\SETUP.EXE with Explorer or My Computer
        
If you are installing on a system other than Windows 95
please consult one of the following  documents:

	WIN31.TXT, DOS.TXT or OS2VDM.TXT

++++++++++++++++++++++++
+ MANNUAL INSTALLATION +
++++++++++++++++++++++++

Note, this document is written from the perspective of installing
TAPEDISK Professional.  The installaion of the Professional version
of TAPEDISK normaly installs into C:\TD654.  If you are installing
the TAPEDISK Demo the default directory for installation is
C:\TD654250. The TAPEDISK Demo V6.5.4 is a 250MB restricted version
of TAPEDISK.

If you have installed this into a different directory please
make adjustments to the following documentation.


++++++++++++++++
+ REGISTRATION +
++++++++++++++++

The TAPEDISK software must be registered.  In all likelihood you
already have registered the software during the automated file
installation procedure so you can skip the following paragraph.

To register our software locate the registration number on the
product box or on the inside cover of the User's Guide.  Once you
have this number use Explorer to find our file TDREG.EXE.  Double
click on this file.


+++++++++++++++++
+ CONFIGURATION +
+++++++++++++++++

You are required to perform one test (to be described below) and add
a few lines to C:\CONFIG.SYS.  If your system has no file of this
name then you must create the C:\CONFIG.SYS file.  An example of the
modified C:\CONFIG.SYS follows:

1) DOS=HIGH
2) DOS=UMB
3) LASTDRIVE=Z
4) DEVICE=C:\WINDOWS\HIMEM.SYS
5) DEVICE=C:\WINDOWS\EMM386.EXE 2600 RAM D=64
6) SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;C:\TD654
7) DEVICEHIGH=C:\TD654\TAPEDISK.EXE /K=1000 /HA=0 /ID=5 /ASK=Y
8) INSTALL=C:\TD654\TDGETMEM.EXE D: /EMS=2500
9) SET ACCDATE=D-

Please do not create or edit your CONFIG.SYS to look like the
above.  The "1)", "2)", ... marks are not to be inserted into the
file: they are simply annotations for this example.


Comments:

1) DOS=HIGH

This is the default. It specifies that at boot time DOS use
the high memory area.

2) DOS=UMB

This specifies that if the memory manager is able to find upper
memory blocks then these blocks will become available for use.

3) LASTDRIVE=Z

This specifies that the DOS Last Drive data structure be created with
a value of Z.  You might be able to omit this line.  This value may
also be different for those running networks.  See you system
administrator.

4) DEVICE=C:\WINDOWS\HIMEM.SYS

This is a Windows driver that make extended memory available to DOS
applications.

5) DEVICE=C:\WINDOWS\EMM386.EXE 2600 RAM D=64

This is a Windows driver that provides memory management in
conjunction with HIMEM.SYS.

This line shows three options:

	2600 To indicate the minimum amount of memory for use
	     by EMS services. In this example it is set to
	     1600 over the /K=1000 value on the TAPEDISK
	     line. This memory is used for a cache for the
	     TAPEDISK drive. As you vary the /K=1000 value
	     you should vary this value.

	RAM  This specifies that the upper memory blocks are
	     to be enabled.

	D=64 Required for some of the DOS Real Mode ASPI
	     managers. For now include this option. Test later
	     to see if this option can be omitted.

Note, if you already have the EMM386.EXE line in CONFIG.SYS then add
these switches and keep any other switches.  Also, if the old
EMM386.EXE line contained an option of NOEMS then remove the NOEMS
option.

For users of QEMM or other memory managers: you do not use the
HIMEM.SYS or EMM386.EXE.  However you must enable EMS memory.  This
is usually done by removing the NOEMS option if it is present.

6) SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;C:\TD654

This sets the PATH variable to include the TAPEDISK directory.

** Note **

Do not use "SET PATH=%PATH%;C:\TD654" as you are not running in
AUTOEXEC.BAT.

The PATH variable is usually set in AUTOEXEC.BAT.  You can also
set it in CONFIG.SYS as we have done here.  Please adjust the
directories to their proper places.  Note, if you do not have
an AUTOEXEC.BAT file we suggest that you set PATH in CONFIG.SYS.
By doing so you can reduce lower memory requirements.  If you
currently are using an AUTOEXEC.BAT we suggest that you not use
the "SET PATH=..." in CONFIG.SYS and at the end of AUTOEXEC.BAT
that you add:

	PATH=%PATH%;C:\TD654

which will append the path of the TAPEDISK utilities to the
PATH variable.

7) DEVICEHIGH=C:\TD654\TAPEDISK.EXE /K=1000 /HA=0 /ID=5 /ASK=Y

This loads the TAPEDISK device driver.  DEVICEHIGH will cause
TAPEDISK.EXE to load high if possible.

The option switches are:

	/HA=0	The ASPI host adapter number. This number may
		be different on your system. We will show you
		how to obtain the host adapter number later on.

	/ID=5	The SCSI id number for your tape drive. This
		number will likely be different on your system. 
		We will show you how to obtain the SCSI id number
		later on.

	/K=1000	This option specifies the number of KB to use
		for the directory cache.  This memory is part of
		the overall cache obtained for use by TDGETMEM.
		You may need to adjust this value depending on
		the storage requirements for all the file names
		and directory names on the TAPEDISK.  We have
		reports that indicate how much of this cache
		is used and this report can be used by you to
		make adjustments to the directory cache. A /K=
		value too small adversely effects performance,
		a value too large wastes memory.

	/ASK=Y	This causes the TAPEDISK device driver to ask
		you if you wish to install the driver. If you
		answer Y (or Enter) the driver will install. If
		you answer N the driver will not install. Thus
		with one configuration you can select whether
		you wish to have TAPEDISK device driver installed.
		
		Note: when using /ASK=Y, at boot time the device
		driver will display the drive letter that may be
		assigned to the TAPEDISK.
		
		You may	remove this switch after testing TAPEDISK
		in which case a drive letter will be assigned to
		TAPEDISK unconditionally.

Note, all switches to the TAPEDISK utility programs require a
space character preceeding the "/" switch character.

8) INSTALL=C:\TD654\TDGETMEM.EXE D: /EMS=2500

TAPEDISK requires that an EMS cache be allocate prior to Windows
executing.  TDGETMEM obtains the cache for use by TAPEDISK.  It has
the following options:

	D:		The drive letter for TAPEDISK.
	/EMS=2500	The size of the cache.

On your system "D:" may not necessarily be assigned to the TAPEDISK.
This drive letter will usually be assigned as the next local drive
letter.  An explanation follows below.

The cache requirements of TAPEDISK are approximately 1500K over
what the directory cache is as specified on the TAPEDISK line.

*** Note, Prior to Windows 95 EMM386.EXE used to use the standard
*** computer value of 1024 for K. This appears to have changed for
*** Windows 95 to use 1000 for K. For this reason you will see the
*** discrepancy between the 2600 on the EMM386.EXE line and the
*** 2500 on the TDGETMEM line.

As you adjust the /K value on the TAPEDISK line remember to
adjust this value as well.

9) SET ACCDATE=D-

This disables the Windows 95 feature that maintains the last
access date of a file.  This is not the modified date. On a
backup tape you usually do not want to disturb the last access
date of a file.  Also this causes unnecessary tape consumption
in tracking the changes to the last access date.  We recommend
that you disable this feature for the TAPEDISK drive letter.
Again, your TAPEDISK drive letter might not be D:. Please vary
the "D" on this line if the drive letter of the TAPEDISK is
other than D:.

The ACCDATE issue is one of the issues addressed in fast.wri.
Please note that at the time of this writing it appears that
ACCDATE does not always block the update of the last access
date and time.

+++++++++++++++++++++++++++++
+ STEP BY STEP INSTRUCTIONS +
+++++++++++++++++++++++++++++

To facilitate installation have NotePad open on this document
and Win95 Explorer running.

The default directory for installation is C:\TD654. If you 
changed the location of installation please modify the
following instructions to take into consideration the different
location of the files.

Switch to the Explorer window and select from the Explorer tool
bar View|Details.  This changes Explorer to display more details
about the files.

In the left window of Explorer locate and select "My Computer".
In the right window of Explorer you will see in the Type column
the list of "Local Disk" drives for your system.  Most systems
will have only one drive listed as of type "Local Disk".  You
may also see "Removable Disk" drives listed.  If you have disk
compression software you will see "Local Disk" with a name of
"HOST for C: (D:)".  Under normal circumstances you will see
adjacent drive letters: C:, D:, E: and so on.  Many systems
will just have C: as the only disk.  The purpose of this
exercise is to determine the next available disk drive letter.

When installing the TAPEDISK device driver the Win95 process
that installs the device driver supplies the next available
drive letter.  In the example above the drive letter of D: was
referenced in the C:\CONFIG.SYS line:

	INSTALL=C:\TD654\TDGETMEM.EXE D: /EMS=2500

The drive letter assigned to TAPEDISK may be other than D:. 
Please change the drive letter "D:" to the next available drive
letter as you determined using Explorer as appropriate. If you
supply the incorrect drive letter the TAPEDISK device driver
will not have it's working memory cache.  Once you reboot Win95
you can use Explorer to verify the correct drive letter.  If the
assigned drive is different from the TDGETMEM drive letter
replace it by editing C:\CONFIG.SYS.

Do not reboot now.  Please read on.

The line added to C:\CONFIG.SYS that installs TAPEDISK.EXE
requires the ASPI host adapter number and the SCSI id number
for the tape drive.  These numbers will vary from system to
system.  Please use the following procedure to obtain these
values:

Use Explorer to locate our utility SCANSCSI.EXE.  Double click
on ScanSCSI.EXE.

ScanSCSI will display the attached SCSI devices in a manner
similar to the following:



  SCANSCSI(V6.5.4)  (c) 1993, 1994, 1995 by TAPEDISK Corporation
      
   HOST | SCSI |  DEV  |  IS  |  IS   |  Vendor

        |      |       |      |       |



  Press any key to continue.

(Don't press any key now, read on...)


You probably do not have as many tape drives on your system
as we do!

From the report generated on -your- system locate your tape
drive.

If you do not see your tape drive then the possible problems
are:

	1) You do not have a SCSI/ATAPI tape drive.
	   Sorry, we only support SCSI drives at this time.
	   Press the return in the DOS-box then X the window.

	2) Your SCSI tape drive is not turned on.
	   Turn on the tape drive.
	   Press the return in the DOS-box then X the window
	   and re-run SCANSCSI.

	3) Your SCSI host adapter is not recognized by Win95.
	   Press the return in the DOS-box then X the window.
	   Install the SCSI host adapter's Real Mode ASPI
	   manager. Following the instructions from the
	   manufacturer of your SCSI host adapter.  If you do
	   not have this driver then you will be required to
	   obtain it from the manufacturer of the SCSI host
	   adapter.  Once the ASPI manager is installed then
	   resume the TAPEDISK installation at SCANSCSI.

When you can identify your tape drive with SCANSCSI you can
continue with these instructions.

In the DOS-box SCANSCSI window, locate the line that identifies
your tape drive.  On that line and under the column titled "HOST
ADAP #" will be the ASPI host adapter number for the ATAPI
and/or SCSI host adapter for your tape drive.  Under the column
titled "SCSI ID" is the ID number for the tape drive.  These two
numbers are to be supplied on the line in CONFIG.SYS that
install the TAPEDISK device driver.  Please record these numbers.
Also, for additional reference, record the vendor name, product
name and the other information for your tape drive.  This
information may be required if our software has problems in
identifying the proper driver for your tape drive.

Now you have all the information that is required to install
the TAPEDISK device driver:

	1) drive letter
	2) ASPI host adapter
	3) SCSI id number

To edit CONFIG.SYS:
-------------------

With your mouse, highlight the following text:

NOTEPAD C:\CONFIG.SYS

Then press <Ctrl>-C to copy the text to the paste buffer.

Click on the Start Icon on the Task Bar, then click on the Run
option. Place the cursor in the Open line and press <Ctrl>-V to
copy the paste buffer.  You should see "NOTEPAD C:\CONFIG.SYS"
(without the quotes).  If so, press <Enter> to edit CONFIG.SYS.

Edit the CONFIG.SYS file to contain information that looks
somewhat like the following example. If CONFIG.SYS does not
exist then indicate that you wish to create it. Please remember
to use the information obtained above and to correct the drive
and directory locations.

DOS=HIGH
DOS=UMB
LASTDRIVE=Z
DEVICE=C:\WINDOWS\HIMEM.SYS
DEVICE=C:\WINDOWS\EMM386.EXE 2600 RAM D=64
rem The old EMM386 line may have had X=nnnn-mmmm
rem keep these values as they are important.
rem Place other disk drive support modules before
rem TAPEDISK. e.g. ASPI manager if required and
rem ASPIDISK drivers also 3rd party disk compression
rem drivers.
rem TAPEDISK can be placed last but you may obtain
rem better memory utilization with different device
rem driver ordering.
rem ...
rem ... Your previous drivers go here
rem ...
rem Then finally comes the lines for TAPEDISK
rem If you have no AUTOEXEC.BAT add the following statement:
SET PATH=C:\WINDOWS;C:\WINDOWS\COMMAND;C:\TD654
DEVICEHIGH=C:\TD654\TAPEDISK.EXE /K=1000 /HA=1 /ID=5 /ASK=Y
INSTALL=C:\TD654\TDGETMEM.EXE D: /EMS=2500
SET ACCDATE=D-

Once these edits are made you are ready to try out TAPEDISK.


++++++++++++++++++++++++++++++++++++
+ Before you restart your computer +
++++++++++++++++++++++++++++++++++++

The TAPEDISK driver is loading as a block mode driver and will
obtain it's drive letter prior to your CD-ROM(s). Therefor your
CD-ROM may move up a drive letter.  We recommend that if the
CD-ROM moves (or hides the TAPEDISK drive letter) that you move
it permanently to a high drive letter (e.g. X:).  Leave one or
two drive letters available after the CD-ROM drive letter(s)
should you later decide to add an additional CD-ROM.  Remember,
TAPEDISK is being installed as a hard disk and the assignment
of the drive letters is made by the Win95 boot process and is
beyond our control.

Changing the drive letter of the CD-ROM is performed in one of
two ways. If you install a real mode driver for the CD-ROM you
will have a line in AUTOEXEC.BAT like the following:

   C:\DOS\MSCDEX.EXE /D:MSCD001 /M:8 /E /L:D /V /s
   
In this example the "/L:D" specifies the (low) drive letter to
use. If this switch is not present on the line then you may
add the /L:x to the command.  We recommend a very high drive
letter.  Therefor we suggest that this option be changed to
"/L:X".

If your Windows 95 system is using the internal CD-ROM driver
then you can change the drive letter in the following manner:

Locate "MyComputer" on the desktop. Right Click on MyComputer.
Select Properties, device manager tab, double click on CD-ROM,
double click on the CD-ROM drive, click on settings tab, then
change the drive letter.

The change will take effect on the next restart.



If you guessed the wrong drive letter for the TAPEDISK, the
cache for the TAPEDISK drive will not be allocated and you will
not be able to use your tapes. Correct this drive letter should
the assigned drive be different than your guess.  Again, use
NotePad to edit CONFIG.SYS.

Each time you change CONFIG.SYS you will be required to restart
your computer.

If you have problems with the new CONFIG.SYS you can single
step the boot process by pressing the F8 key when the initial
"Starting Windows 95" message appears.

IFSMGR: Memory Protection Error

                     This error is due to a bug in Win95.
                     It seldom occurs but when it does
                     it is due to some configuration option
                     causing the IFSMGR to reference a
                     suspected 512K cache that follows the
                     Upper Memory Block handle (0). And
                     this block of memory was not allocated
                     from the memory manager. Some feature of
		     Win95 is violating memory allocation
		     protocols.

                     To correct for this problem we added a
                     switch to TDGETMEM.  The switch is called
                     /WIN95RESERVE=nnnn where nnnn is in K. An
                     example of it's use is:

                     TDGETMEM D: /EMS=2500 /WIN95RESERVE=512

                     You may have to experiment with different
                     values to produce the lowest number that
                     removes the problem.  Your correct value
		     may higher or lower than 512.



++++++++++++++++
+ TAPEDISK GUI +
++++++++++++++++

The TAPEDISK graphical user interface (GUI) is new for Win95!

After a successful boot you are now ready to add a Shortcut to
the TAPEDISK GUI (C:\TD654\TDWIN.EXE).

Use Explorer to locate the TAPEDISK directory (e.g., C:\TD654).
Single click on TDWIN.EXE then select File, Create Shortcut.
You will see a new file appear in the directory titled:

"Shortcut to Tdwin..."

Select and grab this file and drag it onto the desktop.
(You may need to reduce the size of a window so as to expose
the desktop.)

Now the installation of TAPEDISK for Windows 95 is complete.

Please consult the document FASTER.WRI for information on how
to make TAPEDISK run faster under Windows 95.

++++++++++++++++++++
+ Notes on the GUI +
++++++++++++++++++++

While the GUI is performing an operation you will see on the
task bar the startup of an MS-DOS box.  If you are interested,
you can select the MS-DOS box to see what is happening.  Most
operations are quick and you may not have an opportunity to see
what was being done before the MS-DOS box goes away. If you
decide to do this DO NOT cancel this window, minimize it if
you must.  Most of our utilities perform asynchronous I/O to the
SCSI device.  By killing this task you risk terminating the
task while I/O is pending to memory that will be released on
task termination. This may crash your system.

++++++++++++++++++++++++++
+ RULES FOR USE OF TDWIN +
++++++++++++++++++++++++++

To use TAPEDISK there are a few fundamental rules to follow:

1) Launch the TDWIN GUI program by double clicking on it's
   Shortcut.  You may copy the Shortcut to the Start Up group
   if you wish.

2) While you wish to use TAPEDISK keep the GUI running.
   Minimize its window when the GUI is not immediately
   needed. You will not be able to X the window while a tape
   is in use.

3) TAPEDISK is not like a floppy disk.  You cannot just
   insert a tape and have it ready for use.  TAPEDISK tapes
   can hold several hundred different "disks".  Each being
   different versions of possibly different collections of
   disks. The Graphical User Interface will help you keep
   track of "disks" on the tape and provide the means of
   "Loading" the proper disk.

4) Tapes that have never been used by TAPEDISK must be
   formatted. Formatting a TAPEDISK takes only a few seconds
   on a DAT drive and varies up to a few minutes for some
   of the slower drives we support.

5) Once a tape is in the drive and "Loaded" for a particular
   "disk" the tape drive is available for use by all other
   applications running on Win95.  After loading the tape the
   GUI is not required for disk-like use. You can minimize the
   TDWIN GUI at this time.

6) To obtain the performance levels that we have, we perform
   substantial amount of caching.  If your tape drive does
   not have a door lock do not pull out or remove the tape
   without issuing our Unload (i.e. TDUNLOAD) operation. After
   issuing Unload use the GUI function to Eject the tape.
   Eject on tape drives without door locks rewinds the tape to
   the load point. Please do not remove your tape when the
   drive is not at the load point.

   One of the reasons for leaving the GUI running in a minimized
   window is to enforce this unload procedure prior to system
   shutdown.

7) The Diskcopy operation will only copy local disks. It
   appends another "disk" to the TAPEDISK that is, in essence,
   a copy of the disk being backed up.  You can select multiple
   disks to backup in a single operation.

   Note, Diskcopy is unusual in that it operates on TAPEDISK
   tapes that have _not_ been loaded.  Your tape must be
   formatted (but need not be empty) and must have enough room
   to contain a complete backup.  TAPEDISK does not span tapes.

   TAPEDISK Logical Tape can only write to the tape using the
   Diskcopy process.  If you want online write capability to
   the tape then you should upgrade to the professional version
   of TAPEDISK.

Please read the TAPEDISK User's Guide for complete information.


+++++++++++++++++++++++++++++++++++++++++
+ Notes on using Explorer with TAPEDISK +
+++++++++++++++++++++++++++++++++++++++++

Explorer works with TAPEDISK.  Explorer is feature rich but,
is missing a feature that is desirable for use with TAPEDISK.
The missing feature is to disable the application icon display
for unlisted file types.  You may not be aware of this but
when Explorer opens a folder and lists it's contents (and
icons) and encounters a file of unknown type (registration)
Explorer will read the file and search for the program icon or
lack of icon.  On a local disk the overhead is noticeable but
not too severe. On a tape drive with relatively long seek times
this extremely bothersome.

Folders with known file types will open quickly.  Folders with
many .EXE, .DLL, and other files with embedded icons will
take a while to open, in some cases it can take a long time.

If you find this troublesome then we suggest that you consider
upgrading to the professional version of TAPEDISK.  The
professional version of TAPEDISK has additional features that
can correct for this problem.

Windows 95 caches the icons. Therefore the 2nd time you visit a
directory the directory will display fast.  Since TAPEDISK Logical
Tape will write full disk backups you can speed up the icon
lookup by using Explorer to examine the same named folder on your
hard drive prior to examining it on the tape drive. After using
TAPEDISK for a while you will have some idea of which folders
require this extra step.
