Section 1
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.
There are versions of Guest for Windows 95/98, Windows 3.1/DOS
and Macintosh systems:
* For Windows 95/98, run GUEST9X.EXE from the Windows/DOS
Install disk (floppy or CD). If you encounter any problems, see
"GUEST9x.HLP" on the Install diskette.
* For Windows 3.1/DOS systems, run GUEST.EXE from the
from the Windows/DOS Install diskette. Refer to the
GUESTHLP.TXT file on the Install diskette for
additional information on using GUEST.EXE with IBM-
compatible PC's.
* For information on using Guest on Macintosh systems,
refer to the GUESTHLP.TXT file on the Windows/DOS
Install diskette.
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 Guest permanently installs the drivers needed to
support Iomega hardware under Windows 95/98.

Section 3
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 95/98,
Windows 3.1, and DOS.
* 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" disk in an appropriate drive (floppy or CD-ROM),
go to the DOS prompt, and type:
A: <Enter> (or D: where D is your CD-ROM drive)
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 95/98, 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" disk (floppy or CD) for
Windows/DOS into the appropriate computer drive and the
"tools" disk into the Jaz 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>

Cautions and Technical Notes
______________________________
Section 4.1
Microsoft Disk Copy Utilities
CAUTION!
Do NOT use DISKCOPY.EXE or the Windows 95/98 right mouse
CopyDisk utility with your Zip drive. These utilities were
designed for use with floppy drives and do not work
correctly with other removable drives. Use an Iomega disk
copying utility to copy disks (either Copy Machine or Iomega
SCSI Disk Copy).
______________________________
Section 4.2
FDISK
CAUTION!
Do not use FDISK on any removable disk. FDISK is designed
for partitioning fixed disks. Partitioning any type of
removable media can lead to unexpected results.
______________________________
Section 4.3
32-bit Access
If you are using Windows 3.11 or Windows for Workgroups and
want to use Copy Machine, make sure that 32-bit disk and
file access is turned off. (This option is available when
changing virtual memory options under "386 Enhanced" in the
Windows Control Panel.)
NOTE: Windows 3.1 does not support 32-bit access for
removable disks drives. If 32-bit access is not turned off,
the hard drive will NOT appear in the Copy Machine window.
______________________________
Section 4.4
Windows Format Utility
If you are using Windows 3.1, do not use the format utility
available in Windows File Manager to format Zip disks. Use
an Iomega format utility (either Iomega SCSI Format or
Format in Iomega Tools).
______________________________
Section 4.5
Microsoft Backup
Microsoft Backup does not support removable disk drives
other than floppy drives. You can use Copy Machine to copy
files on your hard disk to the Zip drive, or you can use the
Windows File Manager to drag-and-drop files you want to back
up to Zip disks.
______________________________
Section 4.6
Compression
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 4.7
Installing Applications to the Zip Drive
Certain applications and games will install only to a fixed
disk. To install these programs to the Zip drive, use the
Iomega Tools "Make Nonremovable" or "Lock" utility to make
the Zip drive appear as a hard drive to the system. After
the software installation is complete, use "Make Removable"
or "Unlock" to restore disk removability.

Section 5
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 5.1
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. Warp Nine Engineering (formerly
FarPoint Communications) produces an I/O card, F/PortPlus,
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, or you can contact Warp Nine Engineering at
http://www.fapo.com.) Contact your computer dealer if you
wish to purchase a card.

Section 5.2
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 6
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 95/98, 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.
