Section 1
Using the 100MB Zip "tools" Disk
The 100MB Zip "tools" disk included with your Zip drive is a
special dual-format disk which contains Zip Tools software
for BOTH Windows/DOS and Macintosh systems. Before you can
write any files to the disk, the disk format must be set as
EITHER Windows/DOS (IBM-compatible PC) or Macintosh (which
allows you to store your files safely but eliminates the
Tools software files stored under the other format type).
Running the software Setup program under either Windows 95
or Windows 3.1 automatically sets the "tools" disk format to
Windows/DOS and reclaims the Macintosh portion of the disk
for use on PC systems. Similarly, running the Zip Install
program for Macintosh, sets the "tools" disk format to
Macintosh and erases the PC portion of the disk. If you are
installing Zip software support on a DOS-only system, you
need to run the Reclaim program as described in your Zip
Installation Guide to set the disk format and unlock the
disk.
If you use your Zip drive on both PC and Macintosh systems
and want to install Zip Tools on both system types, you need
to purchase an additional "tools" disk for installing Zip
Tools on your second system. (See your Zip Accessory Guide
for ordering information.)
NOTE: The Zip "tools" disk can be used to reinstall Zip
Tools software on the SAME system type (PC or Macintosh) as
the initial installation. Be sure not to delete any of the
original files from the disk in case you ever need to
reinstall your Zip Tools software.

Section 2
Using the Guest Program
The Guest program allows you to use a portable Zip drive on
another computer without having to permanently install
either an Iomega driver or Zip Tools software. All you have
to do is connect the Zip drive to the computer and to an
Iomega Zip power supply, and then run the Guest program from
a floppy diskette to load the Guest driver.
There are versions of Guest for Windows 95, Windows 3.1/DOS
and Macintosh systems:
* For Windows 95, run Guest95 from the "Install" floppy
diskette for Windows/DOS. If you encounter any
problems, see "Help for Guest95" on the "Install"
diskette.
* For Windows 3.1/DOS systems, run GUEST.EXE from the
"Install" floppy diskette for Windows/DOS. Refer to
the GUESTHLP.TXT file on the "Install" diskette for
additional information on using GUEST.EXE with IBM-
compatible PC's. (If you install Zip Tools software
under Windows, you will find the same information in
"Guest Help" in the Iomega Zip Tools group.)
* For information on using Guest on Macintosh systems,
refer to "Guest Help" on the "Install" floppy diskette
for Macintosh.
NOTE: On Windows 3.1, DOS, or Macintosh systems, running
the Guest program provides a temporary driver installation
that is removed when the computer is shut down or restarted.
Running Guest95 permanently installs the drivers needed to
support Iomega hardware under Windows 95.
_________________________________________________________
Section 3
Installing Zip Support on DOS-Only Systems
Many of the application programs included in the Zip Tools
software package require Windows 3.1 or Windows 95. If you
do not have Windows on your computer, you can still use the
Zip drive, but you will not be able to use the Zip Tools
software that requires Windows. This section describes the
software support for Zip drives available for DOS systems
that do not have Windows.
______________________________
Section 3.1
Iomega Driver for DOS
Running the INSTALL program from the DOSSTUFF directory on
the Zip "tools" disk installs Iomega SCSI software to
support your Zip drive. The Iomega SCSI Driver installs as
a device (SCSIDRVR.SYS) in the computer's CONFIG.SYS file,
and because of the way DOS handles drive letter assignments,
this can shift your existing drive letters.
Iomega software for Zip includes a TSR version of the Iomega
Driver (GUEST.EXE) which will not cause any driver letter
shifts when it is installed. If you prefer using the TSR
version of the Driver, you can manually install it in your
AUTOEXEC.BAT file. Refer to "Special Procedures" in the
electronic "Installation Manual" (MANUAL.EXE) for
instructions. (See Section 5 in this file for detailed
instructions on accessing the electronic manuals.)
______________________________
Section 3.2
Zip Tools under DOS
Iomega SCSI software includes a set of utilities that run
under DOS. The Iomega SCSI Utilities handle a number of
tasks related to using removable SCSI drives and disks,
including Zip drives and disks. You can use these utilities
to set software protection options on your Zip disks, copy
data to or from Zip disks, format Zip disks, or lock the Zip
drive so that you can install software to a Zip disk.
You can run the Utilities in an easy-to-use menu mode or
from the DOS command line. To start the utilities in menu
mode, go to the DOS prompt for drive C: (the drive where
your Iomega SCSI software is installed) and type:
cd \IOMEGA <Enter>
SCSIUTIL <Enter>
If you need help running the Utilities, press <F1> anywhere
in the Utilities. Complete reference information on the
Iomega SCSI Utilities is contained in the electronic "User's
Reference Manual" (REFMAN.EXE). (See Section 5 in this file
for information on accessing the electronic manuals.)

Section 4
Installation Troubleshooting
This section includes information for the following
problems:
4.1 Duplicate drive letters
4.2 No drive letter available for the Zip drive
4.3 Guest does not assign a drive letter to the Zip
drive
4.4 Other problems
4.5 Special Information for Users of Adaptec EZ-SCSI
_______________________________
Section 4.1
Duplicate drive letters
If you see two drive letters for your Zip drive or other
drive you are using with the Guest driver (GUEST.EXE),
reboot the computer immediately. Using your Zip drive when
duplicate drive letters are present on the system can result
in data loss.
After the computer reboots, do not load the Guest driver.
You do not need to use Guest to access the Zip drive on this
system because the Zip drive is already being assigned a
drive letter.
Windows 95 Users: If you see multiple drive letters for your
Zip drive or other Iomega drives, refer to the problem
solving information in the electronic "Installation Manual"
(MANUAL.EXE) that is included on the "Install" floppy
diskette for Windows/DOS.
______________________________
Section 4.2
No drive letter available for the Zip drive
You may see this problem when using the Guest program on
DOS/Windows 3.1 systems. For detailed problem-solving
information, refer to the GUESTHLP.TXT file which is located
on the "Install" floppy for Windows/DOS.
_____________________________
Section 4.3
Guest does not assign a drive letter to the Zip drive
If you run the Guest program and it informs you that no
drive letters were added, and yet you cannot access the Zip
drive, there is probably a hardware installation problem.
Carefully check the steps involved in installing your Zip
drive. If you have installed a new adapter, check the
adapter installation as well. If you have more than one
drive connected to a single SCSI adapter, you may have a
SCSI ID conflict or termination problem. For detailed
suggestions to help solve any of these installation
problems, refer to the electronic "Installation Manual"
(MANUAL.EXE) located on the "Install" floppy diskette for
Windows/DOS.
_____________________________
Section 4.4
Other problems
If you encounter other problems while installing or using
Zip Tools software or Iomega SCSI, refer to the electronic
"Installation Manual" (MANUAL.EXE) for additional problem
solving information.
_____________________________
Section 4.5
Special Information for Users of Adaptec EZ-SCSI
Zip Tools and/or Iomega SCSI software can be used on the
same system as Adaptec EZ-SCSI without problems if you:
1. Use the Iomega SCSI driver to support your Iomega
drives. (If you are using Zip Tools software under
Windows 3.1, you must run both the Setup program under
Windows to install Zip Tools and the Install program
under DOS to install Iomega SCSI. See the electronic
"Installation Manual" (MANUAL.EXE) for detailed
instructions.)
2. Use the /I option with SCSICFG.EXE to tell the Iomega
SCSI software to ignore devices you want controlled by
the Adaptec ASPIDISK.SYS device driver.
3. Use the /ID option with ASPIDISK.SYS to specify the
devices you want it to support.
NOTE: Without the /ID option, ASPIDISK.SYS will take
control of all SCSI devices, including your Iomega drives,
and you will be unable to use your Zip Tools software or
Iomega SCSI Utilities.
The remaining information in this section explains how to
use the /ID option with ASPIDISK.SYS and the /I option with
SCSICFG.EXE.
Using the /ID Option with ASPIDISK.SYS:
The /ID option is used to specify the devices you want
supported by your EZ-SCSI software. To use this option,
open your CONFIG.SYS file and locate the DEVICE line for
ASPIDISK.SYS, for example:
device=c:\scsi\aspidisk.sys /d /pause
Leave at least one blank space after the last option on the
line and add an option of the form:
/ID=[SCSI ID#]+[SCSI ID#]+ ... +[Adapter ID#:SCSI ID#]...
Where each device you want ASPIDISK.SYS to support is
specified by its SCSI ID number. The adapter ID number need
not be specified if there is only one SCSI adapter in the
computer, or if the devices to be supported are connected to
the first SCSI adapter in the computer. (The adapter ID
number for the first SCSI adapter is 0; for the second
adapter the ID number is 1.)
For example, if you want ASPIDISK.SYS to control a SCSI hard
drive at SCSI ID 2 on the first or only SCSI adapter, you
would need edit the CONFIG.SYS file and add /ID=2 to the end
of the DEVICE line for ASPIDISK.SYS. (You would also need
to add /I:2 to the end of the DEVICE line for SCSICFG.EXE in
the CONFIG.SYS file to tell Iomega SCSI to ignore the SCSI
hard drive.)
The following example would tell the ASPIDISK driver to
support the devices at SCSI ID 0 and SCSI ID 1 on the first
or only SCSI adapter:
device=c:\dosstuff\aspidisk.sys /d /pause /id=0+1
Here are three other examples of command line syntax for the
ID option. The second and third examples assume that the
computer has two host adapters.
/id=0+4+6 Support devices at SCSI ID's 0, 4, and 6
on host adapter #0
/id=0+1:4+2 Support device at SCSI ID 0 on host
adapter #0. Support device at SCSI ID 4
on host adapter #1. Support device at
SCSI ID 2 on host adapter #0.
/id=0+1+2+1:1 Support devices at SCSI ID's 0, 1, and 2
on host adapter #0. Support device at
SCSI ID 1 on host adapter #1.
Using the /I Option with SCSICFG.EXE:
To tell Iomega SCSI software to ignore devices you want
controlled by the Adaptec device driver, modify the DEVICE
line for SCSICFG.EXE in the CONFIG.SYS file as follows:
DEVICE=C:\IOMEGA\SCSICFG.EXE /I:[ID,LUN,PORT]
Where [ID,LUN,PORT] specify the SCSI ID number, logical unit
number (LUN), and port address (hexadecimal) of the device
you want SCSICFG to ignore. If the device specified is a
host adapter, SCSICFG will ignore all devices connected to
the adapter.
For example, the following command line would tell SCSICFG
to ignore a SCSI hard disk at SCSI ID 0:
DEVICE=C:\IOMEGA\SCSICFG.EXE /I:0

Section 5
Electronic Manuals
The Iomega software package for Windows/DOS includes two
electronic manuals:
* The "Iomega Installation Manual" (MANUAL.EXE) which
contains complete installation and problem-solving
information for Iomega software under Windows 95,
Windows 3.1, and DOS, including reference information
on Iomega ASPI managers.
* The "User's Reference Manual" (REFMAN.EXE) which
contains reference information on Iomega SCSI software,
including the Iomega Driver, configuration program, and
Iomega SCSI Utilities.
To access the Installation Manual, insert the Windows/DOS
"Install" diskette in a floppy drive (the example below
assumes drive A:), go to the DOS prompt, and type:
A: <Enter>
MANUAL <Enter>
You can also run the Installation Manual from the Windows
File Manager by selecting drive A: and double-clicking on
MANUAL.EXE. Under Windows 95, you can access the
Installation Manual by double-clicking on the floppy drive
in My Computer and then double-clicking on the "Manual"
icon.
The User's Reference Manual is located in the DOSSTUFF
directory on the Zip "tools" disk and installed with the
Iomega SCSI software package. Use the following procedure
if you want to access the reference manual before installing
your software:
1. Insert the "Install" floppy diskette for Windows/DOS
into the computer's floppy drive and the 100MB "tools"
disk into the Zip drive.
2. Go to the DOS prompt and type:
a:guest.exe <Enter> (Install floppy in drive A)
or
b:guest.exe <Enter> (Install floppy in drive B)
3. Note the drive letter Guest assigns to your Zip drive
and use it in place of "d:" in the following command
line:
d:\dosstuff\refman <Enter>
If you install Iomega SCSI software using the INSTALL
program, you can access the User's Reference manual from the
C:\IOMEGA directory after the software installation is
complete. Go to the DOS prompt and type:
c: <Enter>
cd \iomega <Enter>
refman <Enter>

Section 6
Cautions
Observe the following cautions if you are installing Zip
software for Windows 3.1 and/or DOS.
______________________________
Section 6.1
DOS DISKCOPY
CAUTION!
When used with removable disks (for example, Zip disks, Jaz
disks, Bernoulli disks, etc.), DOS DISKCOPY does not create
a copy of the source disk on the target disk. DOS DISKCOPY
executes as if copying data from the source to the target
disk; however, after completion, the target disk is
unreadable and must be reformatted. Use an Iomega disk
copying utility to copy disks (either Copy Machine or Iomega
SCSI Disk Copy).
______________________________
Section 6.2
Compression
Stacker 4.0 works with removable disks supported by
GUEST.EXE (for example, Zip disks); however, do not reboot
when Stacker asks if you want to reboot to remove TSR's.
Rebooting removes the Guest driver and eliminates access to
the Zip drive.
DoubleSpace and DriveSpace do not work with disks supported
by GUEST.EXE, but they do work with the Iomega SCSI driver.
If you want to use DoubleSpace or DriveSpace to compress
your Zip disks or other removable disks, install the Iomega
SCSI driver in your CONFIG.SYS file to support your
removable drives. Refer to the electronic "Installation
Manual" (MANUAL.EXE) for detailed instructions on running
the INSTALL program from the DOSSTUFF directory on the Zip
"tools" disk. If you use Windows, also install your Zip
Tools software for Windows by running the Setup program
after installing Iomega SCSI.
CAUTION!
If you are using a compression utility on a removable disk
(for example, a Zip disk), you should make that disk
nonremovable (or lock the disk in the drive) whenever the
compressed volume is mounted. Removing a disk while the
compressed volume is mounted could result in lost data. To
remove the disk, first unmount the compressed volume, then
unlock the drive. Refer to the electronic "User's Reference
Manual" (REFMAN.EXE) for detailed information on locking and
unlocking drives.
CAUTION!
Do not use any disk compression software to compress
removable boot disks.
Iomega SCSI Utilities with Stacker 4.0
When using Stacker 4.0 and Iomega SCSI, mounted, stacked
drives will not appear on the graphical user interface
screen for the Iomega SCSI Utilities. In order to use an
Iomega SCSI utility on a stacked drive, you must first
unmount the drive.
______________________________
Section 6.3
Shifting Drive Letters
The following caution applies only if you are installing Zip
support on a DOS-only system or if you choose to install the
Iomega Driver, SCSIDRVR.SYS, in your CONFIG.SYS file.
CAUTION!
Installing the Iomega SCSI driver may cause your drive
letters (including network drives) to change. This could
affect Windows applications that reference existing drives.
Check your Windows groups and "ini" files. For additional
information, refer to "Relocating Drive Letters" in the
electronic "Installation Manual" (MANUAL.EXE).
_________________________________________________________
Section 7
Pass-Through on the Parallel Port Zip Drive
This section describes how to handle problems you may
encounter when connecting printers or other parallel port
devices to the pass-through connector on the Zip drive.
______________________________
Section 7.1
Printers
The parallel port Zip drive supports most printers on the
pass-through connector; however, some printers require
exclusive use of the parallel port and will not work
correctly when connected to the Zip pass-through. Because
these printers cannot share the parallel port, your system
may stop responding if you attempt to use the printer and
your Zip drive at the same time (for example, if you attempt
to print a file from a Zip disk).
If you are having problems with your printer when it is
connected to the Zip pass-through connector, try the
following:
* Try powering on your computer, printer, and Zip drive
all at the same time by plugging them into the same
power strip and applying power at the power strip.
* If you are using Windows 3.1, disable Disk Watch by
removing it from your Windows Startup folder and then
restarting Windows. Disk Watch periodically wakes up
the Zip drive and checks its status, which temporarily
disables the Zip pass-through.
* Some Print Cache programs may conflict with the
parallel port Zip drive. If you have Print Cache on
your system, disable the audio warning messages for
both Windows and DOS using the reinstall procedure in
the Print Cache manual. (If you encounter problems
reinstalling, please contact your Print Cache Software
Technical Support.)
* If you have Microsoft Print System installed on your
computer, try using it to disable bi-directional
communication to the printer. (Remove the check mark
from the box next to "Use bi-directional
communication.")
* Try setting your printer to "Print to File" whenever
it's not in use. This will enable you to use your Zip
drive without problems as long as you are not printing.
When you want to print a file from your hard disk (or
any disk other than a Zip disk), close any files that
may be open on your Zip disk and return the printer
setting to normal. Do not attempt to access your Zip
drive until the print job is completed and you have
changed the printer setting back to "Print to File."
If you are unable to use your printer and the Zip drive at
the same time, the best solution is to add an additional
parallel port to your computer, then use the Zip drive on
one parallel port and your printer on the other. Most
computer stores carry simple I/O cards that let you easily
add a new parallel port. FarPoint Communications produces
an I/O card which is fully compatible with the Zip drive and
will improve your drive's performance. (Information on this
card is available from Iomega's Automated FAX Help system at
(801)778-5763.) Contact your computer dealer if you wish to
purchase a card.
______________________________
Section 7.2
Other parallel port devices
Parallel port devices other than printers may or may not
work on the Zip pass-through connector. This problem exists
because computer parallel ports were not originally designed
for devices other than printers. If you try placing a
device other than a printer on the Zip pass-through, or
place the Zip drive on another device's pass-through, there
are no guarantees that it will work correctly.
In the future there will be a standard for daisy-chaining
devices on the parallel port; when this standard is
implemented, Iomega will also conform to it. In the mean
time, try the suggestions listed under Section 7.1 for
solving printer problems. If your parallel port devices
still do not operate correctly on the Zip pass-through
connector, or the Zip drive does not operate correctly on
their pass-through, you may want to think about adding an
extra parallel port to your computer as described in
Section 7.1.
_________________________________________________________
Section 8
Optimizing Parallel Port Zip Drive Transfer Speed under DOS
The parallel port model of the Zip drive supports three
modes of data transfer which have different transfer speeds.
To ensure the broadest base of compatibility for the Zip
drive, the Iomega installation software for DOS
automatically uses the most compatible, but slowest,
transfer mode. In this mode, the transfer speed for the Zip
drive is about 2MB to 6MB per minute, depending on the
computer's processor speed.
If the computer has a bi-directional parallel port, the Zip
drive can be set to use a mode which provides data transfer
speeds of 6MB to 17MB per minute, depending on the
computer's processor speed. (If you are not sure whether
your computer has a bi-directional parallel port, refer to
the owner's manual that came with your computer.)
The fastest mode supported by the Zip drive requires a
special "Enhanced Parallel Port" (EPP) chip set to be
present on the host computer. In this mode, the data
transfer speed for the Zip drive is about 17MB to 22MB per
minute, depending on the computer's processor speed.
Because of the variety of EPP chip sets, and because there
are some chip sets that mimic a true EPP chip but do not
support EPP transfers, not all systems with "EPP" can
support this mode for the Zip drive.
Iomega software for Zip includes a parallel port accelerator
that can automatically set up both your computer and your
Iomega software to use the fastest transfer mode for the Zip
drive that is supported by your computer hardware. Under
Windows 95, you can run the parallel port accelerator by
double-clicking on the icon in the Iomega Tools folder on
your Start Programs menu. For Windows 3.1, double click on
the "Parallel Port Accelerator" icon in your Iomega Zip
Tools Windows group.
Under DOS, run the OPTPPM1.EXE utility as follows:
Step 1: If you have not already done so, install your Zip
software package following the instructions in step 10 of
the Zip Installation Guide.
Step 2: Go to the DOS prompt for drive C: and type:
cd \iomega <Enter>
optppm1 <Enter>
NOTE: If you wish to restore the default settings on your
system, run "OPTPPM1.EXE /NIBBLE" from the DOS prompt.
(This works under Windows 3.1 as well as DOS.)
Download Driver Pack
After your driver has been downloaded, follow these simple steps to install it.
Expand the archive file (if the download file is in zip or rar format).
If the expanded file has an .exe extension, double click it and follow the installation instructions.
Otherwise, open Device Manager by right-clicking the Start menu and selecting Device Manager.
Find the device and model you want to update in the device list.
Double-click on it to open the Properties dialog box.
From the Properties dialog box, select the Driver tab.
Click the Update Driver button, then follow the instructions.
Very important: You must reboot your system to ensure that any driver updates have taken effect.
For more help, visit our Driver Support section for step-by-step videos on how to install drivers for every file type.
