     BEFORE YOU INSTALL THE SUPERDISK DRIVERS: SYSTEM REQUIREMENTS

1. Make sure your computer's Parallel Port is functioning properly.  If 
   you were using other devices, such as printer or scanner, attached 
   to your Parallel Port, you can be sure it is working.

2. Make sure your computer is running DOS 6.0 or higher version, 
   Win 3.x, Win95, Win 98 or Win NT.

3. Use the cables provided in the box.  (Don't use just any cables.)

4. Check your hardware:

  * Make sure you have power to the SuperDisk drive by plugging it into 
    a separate outlet and inserting a SuperDisk diskette. The drive 
    does a test-read of the disk and makes initialization sounds. If no 
    sound comes from the drive, the drive might not have power to it.

  * Check the connections at the back of the SuperDisk drive or try a 
    different outlet.

  * If the drive still does not work, return the drive to your retailer 
    and get a replacement SuperDisk drive.

5. Check to see if a file named DRVWPPQT.VXD exists on your system 
   using the following steps:

  * Once in Windows 95 or Win 98, click on the Start button.

  * Select Find > Files or Folders.  Make sure you search all your hard 
    drives.

  * In the Named box, type DRVWPPQT.VXD

  * Click on Find Now.
 
  * The file is usually located in C:\Windows\System\Iosubsys. If you 
    find the file, rename the file extension to .VX_(i.e.DRVWPPQT.VX_).

    NOTE: If the file is hidden, go to: 

      View > Options > View and select Show All Files > Apply. 

6. If you are installing the SuperDisk drive in a Windows NT 
   environment, make sure you have administrator rights.  If you do not 
   have Admin. rights, contact you system Administrator.

7. If you have McAfee virus scanning Software v 3.0.2, you must upgrade 
   this software before installing the SuperDisk drive.  This can be 
   done by downloading the latest update from McAfee's Web page.



INSTALLING THE SUPERDISK DRIVE

1. Shut down and turn off your computer and all other devices including 
   your printer.

2. Plug the power pack to the power connector on the back of the 
   SuperDisk drive and to an active outlet.

3. Connect the Parallel Cable provided in the box.  Connect it from the 
   computer's printer port to the back of the SuperDisk drive.  This 
   connection is the one closest to the power jack.

4. Do not connect any other device to the pass-through port of the 
   SuperDisk drive.  Wait until you have a fully connected and running 
   SuperDisk drive before you start adding other devices such as a 
   printer or a scanner.

5. Do not have anything connected between the computer's printer port 
   and the SuperDisk drive. If you have an A/B switch, you need to 
   remove it while installing the SuperDisk drive.

6. Power up your computer.

7. If there is any software running in the background, make sure you 
   disable it.

8. Insert the appropriate installation diskette in your floppy drive.

9. Go to: Start > Run > a:\setup.exe

10. Proceed through the installation.

11. Once you finish the installation, restart your computer.

12. Go to My Computer and check for a SuperDisk drive letter.

Note:  For DOS users, see instructions provided in the Read me file 
provided with the DOS drivers.


TROUBLE SHOOTING AND OPTIMIZATION


INTRODUCTION

The Imation SuperDisk -- Parallel Port Drive (PPD) is designed to 
operate on a wide variety of systems with most Super-IO chip 
combinations for use with the parallel port.  Unfortunately only 
recently have standards been created and followed that provide a 
uniform method to interface devices such as scanners, video grabbers, 
tape drives, etceteras to the parallel port. Because of this, it is 
possible for installation problems to arise. This guide will help the 
user adjust computer settings and driver settings to operate as 
reliably and fast as possible.

The parallel port in your computer is setup by a variety of methods 
depending upon the manufacturer and age of the computer. Unfortunately, 
there is no standard method for configuring a port.  Some ports, 
especially older ones, use jumper blocks or switches to select 
different options.  Others allow configuring in software, using a 
utility provided on disk from the manufacturer.  A port on a system 
motherboard may have configuration options in the system setup screens 
(the CMOS setup) that you can access on boot-up.  On ports that meet 
Microsoft's Plug and Play standard, Windows 95 or 98 can automatically 
assign an available port address and IRQ level to a port.

In most modern computers entering the CMOS setup for your computer can 
modify these settings. Refer to your system or port's documentation 
for specifics on how to get into the CMOS set-up utility to configure 
a port.  Many ports can be adjusted in a limited way via the Device 
Manager in Windows 95 or 98.

If you encounter a problem while reinstalling or updating the SuperDisk 
Parallel Port Driver, refer to section I below.

(I) DRIVER REINSTALL OR UPDATING CONFLICTS EXPLAINED

If you have previously installed the SuperDisk Accelerator (SDA), and 
decide to reinstall or update the SuperDisk Parallel Port Driver for 
Windows 95 or 98 a system exception will likely occur.  Typically the 
system error will result in an incomplete install of the PPD.  This 
conflict can be resolved by completing the following procedure:

A. Restart your PC in normal mode.

B. Remove the SDA software by:
   1. Clicking on Start >> Settings >> Control Panel >> 
      Add/Remove Programs
   2. Highlight "Imation SuperDisk Accelerator" on the program list.
   3. Click the "Add/Remove" button, and then click "Yes".
   4. Answer "Yes" to the question "Do you wish to restart now?"
   5. After the PC restarts:
      Click on Start >> Settings >> Control Panel >> Add/Remove Programs

And follow the directions for parallel port driver installation from a 
floppy disk.

C. After installation is completed, reinstall the Imation SuperDisk 
   Accelerator according to the procedure on the Accelerator install 
   disk.


(II) SAFE MODE INSTALL

In the great majority of systems the install will proceed without any 
problems. In those few cases where problems occur this alternative 
install procedure should get your SuperDisk drive up and running. This 
alternative method is a two step process. First the driver is 
installed while in Windows 95 "Safe Mode" and second, command line 
switches are added to the adapter settings for the driver before 
loading. To install the driver:

1) Restart your computer and when the message "Starting Windows 95..." 
appears press the F8 key immediately. A menu screen should appear. Use 
the down arrow key to select Safe Mode and press Enter. Once the 
computer has booted into Windows Safe Mode, install the driver via the 
instructions in the LS-120 Installation Guide.  Use the suggested 
default directory, as the driver installs a message will appear in the 
window titled "Hardware Initialization Failure" -- Select the option 
"I will connect the Imation SuperDisk Drive -- Parallel Port later."  
Click on "Finish".

2) Changing the Adapter Settings: Launch the Connect-It software. 
Locate and double-click on the program named CONX-IT.EXE found in the 
folder at "C:\Program Files\Imation\SD120PPD". Select the Settings 
Manager tab. Under "Modes of Operation" select Safe, then click "OK" 
and the necessary buttons that take you to "Finish".  Now click 
"Finish".  Restart your computer normally.

Note: If your computer froze during a previous install it is best to 
shut your computer off before rebooting to insure that the port 
registers are initialized correctly.

With the adapter settings made during the Windows Safe Mode of 
operation most systems should find the drive and will operate with 
these settings. To get maximum performance from your SuperDisk drive 
some optimization of either the adapter settings or the parallel port 
settings may be needed.  Please read the following sections on how to 
optimize your SuperDisk drive for performance.


(III)	OPTIMIZATION 

Parallel Port settings for perpherals:

PS/2-type (Simple Bi-directional)

An early improvement to the parallel port was the bi-directional data 
port introduced in IBM's model PS/2.  The bi-directional port enables 
a peripheral to transfer eight bits at once to a PC.  The term 
PS/2-type has come to refer to any parallel port that has a 
bi-directional data port but doesn't support the EPP or ECP modes 
described below.  Byte mode is an 8-bit data-transfer protocol that 
PS/2-type ports can use to transfer data from the peripheral to the PC.

EPP

The EPP (enhanced parallel port), as on the PS/2-type port, has 
bi-directional data lines.  An EPP can read or write a byte of data 
in one cycle of the ISA expansion bus, or about 1 microsecond, 
including handshaking, compared to four cycles for the PS/2-type port.  
An EPP can switch directions quickly, so it's very efficient when used 
with disk and tape drives and other devices that transfer in both 
directions.

ECP

The ECP (extended capabilities port) like the EPP, is bi-directional 
and can transfer data at ISA-bus speeds.  ECP ports have buffers and 
support for DMA (direct memory access) transfers and data compression.  
ECP transfers are useful for printers, scanners, and other peripherals 
that transfer large blocks of data. 

With the Imation SuperDisk PPD it is usually desirable to have the 
parallel port CMOS settings set to EPP mode. The driver will then 
modify the port via active settings at boot up time. If EPP mode causes 
a conflict with another driver then some experimentation may be 
required to find a satisfactory compromise.  Other possible options 
might be PS/2 Bi-directional, or ECP mode.  Several variations of each 
mode may be available. 

Base address:

Printer ports normally have three possible hex-based I/O port 
addresses: 03BCh, 0378h, and 0278h. The computer's BIOS will search for 
ports from the highest to the lowest address; the first active address 
will be defined as LPT1, the second as LPT2. Most computers only have 
one LPT port and usually is set to 0378h. 

NOTE: If your system's port address is 03BCh it will not operate in EPP 
mode. Change the port address to 0378h or 0278h if you want EPP 
performance.

Interrupt ReQuest (IRQ):

By convention if your printer port is at address 0378h the normal IRQ 
is 7, if at address 0278h the default IRQ is 5. Some systems do not 
have an IRQ assigned to the port.  For optimum performance you should 
have an IRQ assigned. In Windows 95 the IRQ can usually be assigned 
via the Device Manager. 

Changing the port settings -

Windows 95 or 98:

To get into the device manager Right Click on the "My Computer" icon 
and click on the properties label. Now click the Device Manager tab. 
A list of hardware devices should be seen. Using the scroll bar arrow 
on the right, move down to PORTS (COM & LPT). Double click on PORTS or 
click on the plus(+) icon next to it.  Now double click on the label 
Printer Port (LPT1). Click on the Resources tab.  There are three 
possible parameters: Input Output Range (Base Address), Interrupt 
Request (IRQ), and DMA (Direct Memory Access) channel.

Some systems have only the base address specified, most also have an 
IRQ assigned and in some a DMA channel is specified. If a DMA channel 
is assigned you most likely have an ECP port.

Below the dialog window that displays the settings, click on "Set 
Configuration Manually". A check box labeled "Use Automatic Settings" 
now appears. Un-check the box. The Change Settings button and "Settings 
Based on..." areas should become active (un-grayed). Depending on the 
version of Windows 95 or 98 you are using, click the Down Arrow next 
to the "Settings Based on" box to select "Basic Configuration 1" (or 
the configuration that best fits your need. This should add the IRQ 
assignment to the port. If the IRQ is not correct, (i.e. 7 for base 
address 0378 or 5 for 0278), follow the procedure below to adjust 
accordingly.

NOTE:  The new assignments you make should always match the system's 
CMOS settings.

Use the mouse to click on the "Interrupt ReQuest" text under Resource 
type and then press the Change button. Depending on the version of 
Windows, you will either see a window titled "No Modifications Allowed" 
in which case only Windows can choose your set-up (in this case proceed 
to section III.) Otherwise, a dialog box labeled "Edit Interrupt 
Request" will pop up that allows you to change the settings using the 
up-down arrows. Click on the arrow buttons to get to the correct 
interrupt (7 or 5). Be sure the Conflict Information window is 
reporting the message; "No devices are conflicting." before clicking 
on the "OK" button. If any devices are conflicting, resolve them before 
proceeding. After making the appropriate settings close the System 
Properties box by clicking on the necessary "OK" buttons. Now restart 
your computer.

NOTE: If the CMOS settings have features to change the port address, 
IRQ, etc. then these setting should be updated first. They should match 
the device manager settings.

Windows 3.1 and DOS:

In these operating systems setting the I/O address and IRQ's are 
usually done via jumper settings on your adapter board or the main 
motherboard. If the I/O port is on the main board you may have some 
control of the port settings in your CMOS setup utility. Various 
computer brands use a variety of key combinations to enter the setup 
mode. Usually a message will appear during boot up to instruct you on 
the proper procedure. Refer to your computer user manual if you don't 
know how to enter the CMOS setup.

Microsoft DOS 5.0 and above come with a useful utility called 
Microsoft Diagnostics (MSD.EXE). MSD will report the settings for 
the various pieces of system hardware.  Run this program to get your 
current port and IRQ settings.

(IV)  DRIVER ADAPTER SETTINGS:

The driver for the SuperDisk PPD is named SD120PPD with a suffix of 
SYS, EXE, or MPD depending upon your operating system. A number of 
command line switches are available to tweak the driver to optimize 
its operation with your parallel port. The options are:

/r(0-11) , /w(0-5), /de, /di, /ni, /dp, /PORT=0x0xxx, /IRQ=7. 

The safest and also the slowest switches to use to get your system 
running are Safe Mode. It uses the settings /r2 /w2 /de /di /ni.  When 
these settings are used the driver will operate with; read speed 2, 
and write speed 2, EPP mode disabled, Interrupt (IRQ) Disabled, and 
I/O Chip initialization disabled.

The following table describes each switch option:

/rx - x ranges from 0 to 12

Where:
     /r0  = Nibble Fast
     /r1  = Nibble normal
     /r2  = Nibble Slow
     /r3  = Unidir fast
     /r4  = Unidir normal
     /r5  = Unidir slow
     /r6  = Tecra fast
     /r7  = Tecra normal
     /r8  = Bi-dir fast
     /r9  = Bi-dir normal
     /r10 = EPP normal
     /r11 = EPP fast
     /r12 = ECP
  
/wy - y ranges from 0 to 5

Where:
     /w0  = SPP fast
     /w1  = SPP normal
     /w2  = SPP slow
     /w3  = EPP normal
     /w4  = EPP fast
     /w5  = ECP
  
NOTE: When writing data the parallel port can always output data 8 bits 
at a time, while in read mode the data may be read in either 4 bit 
(status lines), uni-dir(ectional) 8 bit (using control and status 
lines), bi-dir(ectional) 8 bit, EPP or ECP mode. Therefore, more mode 
parameter combinations exist in read mode than in write mode.

Additional switches for advanced functions:

/db - Disables EPP BIOS check
/de - Disable Epp check
/dp - Skip PS/2 DMA Arbitration disable
/di - Operate in polled mode
/fe - force 386sl EPP initialization
/fp - Disable PS/2 DMA Arbitration
/ni - Skip chipset initialization
/ix - force int in 'x' (7 or 5)
/IRQ:x - force irq 'x' (1 to 15)
/PORT:xxx -> force portbase xxx
/P:xxx -> force portbase xxx
/sf - Skips fast mode detection

The command line switches can be used in any combination and order, 
only one switch for each option of course. Use lower case letters. 
For optimum performance use only the switches necessary for your 
system. The switches are usable with either the Windows 95 or 
Window 3.1 driver. 


(V) WINDOWS 3.1 and DOS 

In Windows 3.1 and DOS the driver is loaded and installed by entries 
in the CONFIG.SYS file in your root directory of the C: drive.

The entry should look like this. 

  REM ** Lines added by SuperDisk Drive- Parallel Port Start **
  [COMMON]
  DEVICE=C:\SD120PPD\SD120PPD.SYS
  DEVICE=C:\SD120PPD\ASPIHDRM.SYS /S
  REM **Lines Added by SuperDisk Drive-- Parallel Port End ***

NOTE: If you are running DOS 5.0 or earlier you can use EDIT.EXE to 
remove the statement [COMMON], to prevent the error message when 
CONFIG.SYS is being processed.

 Syntax for the driver is:

 DEVICE=C:\SD120PPD\SD120PPD.SYS [/rx] [/wy] [/de] [/di] [/ni] [/db] 
                 [/sf] [/fe] [/ix: or /IRQ:x] [p:xxx,or /PORT:0xxxx] 

 [ ]   are optional parameters (do not include the brackets)
 /     must proceed each parameter.
       a space should separate each parameter.

Type either EDIT CONFIG.SYS from the DOS prompt or SYSEDIT from 
Windows after clicking Start > Run, to make changes in the CONFIG.SYS 
file.

HINT: You can experiment with switches in DOS mode using the 
SD120PPD.EXE and ASPIHDRM.EXE programs until the drive is recognized 
and the driver is loaded. Re-booting the computer to make additional 
changes will not be required unless the driver successfully loads. 

DOS ONLY COMPUTERS 

If you are attempting to use the drive on a DOS only machine you need 
to extract the files first by installing the SuperDisk Windows 3.1 
software. It is suggested that you install drivers first on a second 
computer with the Windows 3.1 operating system installed and then copy 
the SD120PPD directory to a new disk and copy the edited CONFIG.SYS 
file to it as well. Modify the CONFIG.SYS file in the DOS machine with 
the same entries.  The driver is now ready to run in a DOS only machine.

(VI)	WINDOWS 95 OR 98

Command line switches or parameters can be applied in Windows 95 or 98 
by using the Device Manager which is accessible through System 
Properties.
 
To get to the device manager Right Click on the "My Computer" icon and 
click on the properties label. Now click the Device Manager tab. A list 
of hardware devices should be seen. Using the scroll bar arrow on the 
right, move down to SCSI controllers. Double click on SCSI or click on 
the plus(+) icon next to it.  Now double click on the label Imation 
SuperDisk Drive - Parallel Port.  Click on the Settings tab.  Command 
line parameters listed in section III can be entered in the box below 
Adapter Settings.  When finished click "OK" and then "OK".  Restart 
your PC in order for the changes to take place.

NOTE: Be sure to enter each parameter with a leading "/" and a trailing
 " " (space).

(VII)  WINDOWS NT 

The command line switches described above can be applied to Windows NT 
by using REGEDT32.  Click:

RUN >> REGEDT32 <Enter>

to launch Regedt32. Five cascaded windows should appear, click on the 
one titled HKEY_LOCAL_MACHINE. Then use your mouse to traverse the path 
to the desired key. Successively click on:

SYSTEM > CurrentControlSet > Services  > sd120ppd  > Parameters > Device 

On the right side of the window will be a key named "DriverParameter".  
Double click on the "DriverParameter" option.  A string editor will pop 
up. Type in the desired driver options and click "OK".  Leave the 
"/share" switch intact if you want to use your printer with the drive.  
Exit REGEDT32. Restart your PC in order for the changes to take place. 

NOTE: Be sure to enter each parameter with a leading "/" and a trailing 
" " (space). 

(VIII)  PRINTER PORT PROBLEMS:

With the SuperDisk parallel port drive your printer can plug directly 
into the pass through port on the drive. Printing operation should be 
the same as without the SuperDisk drive attached.  During the 
development of the IEEE-1284 specification that defines how the 
parallel port may be used with advanced printers and peripheral 
devices some mistakes were made that in some cases have caused 
conflicts with ports that are shared between some printers and other 
devices.  Software solutions are being implemented to work around 
these situations. Until these solutions are available here are some 
work-around hints to allow the shared use of the parallel port with 
your SuperDisk Drive.

Some printers use an "active" driver that is always talking to the 
printer and will not release the bus to the SuperDisk drive. In some 
cases this "bi-directional" mode can be disabled from within the 
printer driver. In some models it can be un-selected during the printer 
driver install.  To determine if this is your problem try removing the 
printer driver from the system to see if the drive works correctly 
alone. If it does, contact your printer manufacturer to see if they 
have an updated driver to correct the problem. Alternately determine 
if you can install the driver without the active status mode. Most of 
the printer manufacturers maintain Internet sites where new drivers 
may be downloaded.

While in theory it should be possible to print and use your SuperDisk 
drive concurrently, it is not recommended. The printer driver and 
printer hardware may prevent this multi-tasking to take place 
correctly. Such activity may result in improper printing, or possibly 
system "hanging" problems. 

If you are using the SuperDisk Accelerator software be sure all 
SuperDisk drive activity has ceased before launching a print job. 
If you accidentally start a print job while the drive is in operation 
you can pause or abort the printing by right clicking on the printer 
icon in the task bar tray, open the active printer, click on the print 
job, and then select pause or abort from the options menu. 

(IX)  DO'S AND DON'TS

DO remember to install your copy of SuperDisk Accelerator software 
after the SuperDisk drive is working properly to enjoy improved data 
throughput and convenience.

Don't use Windows 95 Microsoft Backup with the SuperDisk drive, as 
it will not support disk spanning.  (Windows 98 Backup is a different 
program and will work properly.)

Don't use the Microsoft DISKCOPY program. It only works with standard 
floppy disk drives.

Don't use the Windows95 FORMAT utility. It will not work correctly 
with the parallel port drive.

(X)  IF FURTHER SUPPORT IS NEEDED

If after following all the directions above, in some rare cases it may 
be necessary to purchase a new parallel port adapter board. A number 
of manufacturer's supply ISA parallel port plug in boards in the $30.00 
price range. It may also be desirable to use a second parallel port if 
you have a printer conflict that can not be solved on the shared port. 
Be sure to check to see if you have available system resources before 
purchasing additional hardware.
