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
eliminates files stored under the other format type).
Running the Zip Tools software Setup program under Windows
3.1 or the Setup95 program under Window 95 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 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 your Zip drive on a
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 one of the
"Install" floppies 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 Windows/DOS
"Install" floppy. If you encounter any problems, see
"Help for Guest95" on the "Install" floppy.
* For Windows 3.1/DOS systems, run GUEST.EXE from the
"Install" floppy. Refer to the GUESTHLP.TXT file on
the "Install" floppy for additional information on
using Guest 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 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
The SETUP.EXE program on the "Install" floppy disk for
Windows/DOS runs correctly only under Windows. 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 that is installed when you follow
the software installation instructions presented in the
printed "Zip Installation Guide" 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 Driver
(GUEST.EXE) which will not cause any driver letter shifts
when it is installed. Complete comparative information on
SCSIDRVR.SYS and GUEST.EXE is contained in the electronic
"User's Reference Manual" (REFMAN.EXE) which is installed
with the software packages for Windows 3.1 and DOS. If you
prefer using the TSR version of the Iomega Driver
(GUEST.EXE), you can manually install it in your
AUTOEXEC.BAT file. Refer to either the "User's Reference
Manual" or the electronic "Installation Manual" (MANUAL.EXE)
for manual installation instructions. (See Section 5 in
this file for detailed instructions on accessing the
electronic manuals.)
NOTE: Iomega SCSI includes optional CD-ROM support. Refer
to Section 7 in this file for additional information on
installing the Iomega CD-ROM driver.
______________________________
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 problem solving 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 Zip Windows/DOS
"Install" floppy diskette. (See Section 5 in this file for
information on accessing the electronic manuals.)
______________________________
Section 4.2
No drive letter available for the Zip drive
You may see this problem when using the GUEST.EXE 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, it indicates that the driver is unable to locate the
Zip drive. This is probably due to a hardware installation
problem. For detailed problem-solving information for both
Windows 95 and DOS/Windows systems, refer to the electronic
"Installation Manual" (MANUAL.EXE) which is located on the
"Install" floppy 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 5 contains detailed
instructions on accessing the electronic manuals.
_____________________________
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 Setup to install Zip
Tools and Install 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 remainder of this section details how to use the /ID
option with ASPIDISK.SYS. For information on using the /I
option with Iomega software, refer to the electronic "User's
Reference Manual" (REFMAN.EXE). (See Section 5 in this file
for detailed instructions on accessing the electronic
manuals.)
To specify the devices you want supported by your EZ-SCSI
software, you need to add an ID option to the DEVICE line
for ASPIDISK.SYS in your CONFIG.SYS file. Here's an example
of an ASPIDISK DEVICE line:
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 IDs 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 IDs 0, 1, and 2
on host adapter #0. Support device at
SCSI ID 1 on host adapter #1.

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.
* The "User's Reference Manual" (REFMAN.EXE) which
contains reference information on Iomega software for
DOS/Windows 3.1, including the Iomega SCSI driver
(SCSIDRVR.SYS), the Guest driver (GUEST.EXE), the
Iomega SCSI Utilities, and the Iomega ASPI managers.
To access the Installation Manual, insert the Windows/DOS
"Install" floppy 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 installed in the C:\IOMEGA
directory if you install Iomega SCSI software using the
INSTALL program. To access User's Reference, go to the DOS
prompt and type:
c: <Enter>
cd \iomega <Enter>
refman <Enter>
If you install Zip Tools for Windows using the Setup
program, you can access the User's Reference manual from the
ZIPTOOLS directory on drive C after the software
installation is complete. Use the Windows File Manager to
locate REFMAN.EXE in C:\ZIPTOOLS, and double-click on the
filename.
_________________________________________________________
Section 6
CD-ROM Support
Iomega SCSI software includes support for CD-ROM drives.
The Iomega SCSI CD-Player driver has been fully tested with
a wide sample of CD-ROM drives from different manufacturers,
and most drives showed full compatibility, working with both
data and audio.
Use the following procedure if you wish to install Iomega
SCSI CD-ROM support:
Step 1. Insert the 100MB Zip "tools" disk into the Zip
drive.
Step 2. Insert the "Install" floppy for Windows/DOS into
the computer's floppy drive.
Step 3. Run GUEST.EXE from the "Install" floppy diskette.
Note the drive letter Guest assigns to your Zip drive.
Step 4. Run D:\DOSSTUFF\INSTALL.EXE /2 (use the Zip drive
letter in place of D:).
This procedure runs the Iomega SCSI Install program and
automatically installs the Iomega SCSI CD-ROM driver if the
CD-ROM drive is CONNECTED at the time of installation and if
the operating system is MS-DOS 6.0 or higher. If the CD-ROM
driver does not install automatically on your system, you
can install it manually after the Iomega SCSI driver is
installed. Refer to Section 2.3 of the Iomega SCSI Manual
for information on installing the Iomega SCSI CD-ROM driver
manually.
NOTE: The Iomega SCSI Driver supports the Zip drive, so you
will not need to use the Guest driver after Iomega SCSI is
installed. To speed up your computer's boot time, you can
remove or remark out the GUEST.EXE line in your AUTOEXEC.BAT
file.

Section 7
Cautions
______________________________
Section 7.1
DOS DISKCOPY
CAUTION!
When used with removable disks (for example, Zip 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 Iomega SCSI Disk Copy
or Copy Machine).
______________________________
Section 7.2
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 Zip Installation Guide for
IBM-compatible PC's 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 Zip Tools 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 7.3
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 "User's Reference Manual" (REFMAN.EXE).
_________________________________________________________
Section 8
Pass-Through on the Parallel Port Zip Drive
The Zip parallel port supports printers on the pass-through
connector; other parallel port devices may or may not work.
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, here are some hints that may help the operation of
your Zip drive and other parallel port devices.
* If you are running in Windows 3.1 or in a Window's DOS
box and are seeing performance problems with your
printer or with other devices that you are trying to
place on the Zip pass-through, remove ZipWatch from
your Windows Startup folder and restart Windows.
ZipWatch periodically wakes the Zip drive up and checks
its status; when the Zip drive wakes up, the Zip pass-through is temporarily disabled and this will interfere
with the operation of the device connected to the Zip
pass through connector. This should not affect
printers other than to slow them down a tiny bit, but
may interfere with other pass-through devices.
* Some Print Cache programs may conflict with the
parallel port Zip drive. If you experience problems
printing, and Print Cache is already on your system,
disable the audio warning messages for both Windows and
DOS using the reinstall procedure in the Print Cache
manual. If this still does not resolve the problem,
please contact your Print Cache Software Technical
Support.
* If you have other parallel port devices and they will
not work on the Zip pass-through, or the Zip will not
work on their pass-through, you may want to think about
adding an extra parallel port to your computer by
adding an additional I/O card to your computer.
* If you are seeing problems when you boot your computer,
and you are powering ON your Zip drive before turning
your computer on, try powering them at the same time by
hooking them to the same power strip and applying power
at the power strip.
_________________________________________________________
Section 9
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.
