     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 on the disk, the disk format must be set as

     EITHER Windows/DOS (PC) or Macintosh (which eliminates files

     stored under the other format type).  Running the Zip Tools

     Software Setup program under Windows or the Iomega SCSI

     Install program under DOS automatically sets the Zip 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 Zip

     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 Zip 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

     "Zip Install" floppies to load the Guest driver.

     

     There are versions of Guest for both Windows/DOS and

     Macintosh systems.  For Windows/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 Zip Install floppy for Macintosh.

     Section 3

     Speed Options for the Parallel Port Zip Drive

     

     NOTE:  If you are unsure about the information in this

     section, do not attempt to change the transfer speed for

     your Zip drive.

     

     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 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. 

     To be able to use either of the two faster transfer modes

     supported by the Zip drive, the host computer must meet the

     requirements for the faster mode and be specifically

     configured to use it.

     

     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.

     

     If you believe that your computer has a bi-directional

     parallel port or an EPP chip set, use the following

     procedure to test whether your system will support a faster

     data transfer mode for the Zip drive:  

     

     Step 1:  Locate your installed copy of the GUEST.INI file.

     This file is normally installed in the ZIPTOOLS directory on

     drive C:

     

     Step 2:  Save a backup copy of GUEST.INI so that you can

     reference it if needed in the future.  

     

     Step 3:  Use a text editor to open the GUEST.INI file.  You

     can use the Notepad in Windows, the DOS EDIT program, or any

     other ASCII text editor to edit the GUEST.INI file.

     

     Step 4:  Find the line where ASPIPPA3.SYS is referenced. 

     This line should read something like:

     

          ASPI=ASPIPPA3.SYS SCAN /INFO SL360=NO SMC=NO

     

     Step 5:  Remove the statements "SL360=NO" and "SMC=NO" from

     the line.  The line should now read:

     

          ASPI=ASPIPPA3.SYS SCAN /INFO

     

     Step 6:  Save the changes to the GUEST.INI file and exit the

     text editor.  If you are using an editor that has a variety

     of file formats, be sure to save the GUEST.INI file as ASCII

     text or DOS text.

     

     Step 7:  Reboot the computer.  If Zip Tools software is not

     installed, load GUEST.EXE.

     

     Step 8:  Test communication with your Zip drive as follows: 

     (a) Copy a file from drive C: to your Zip disk.  (b) Read

     the file back from the Zip disk and compare it to the

     original file to make sure the data transfer was accurate.

     

     If communication appears normal, you may see an increase in

     the speed of data transfers.  If this is the case, you're

     done.  Enjoy the enhanced performance of your Zip drive.

     

     If the computer hangs, or if communication to the Zip drive

     does not perform to previously known levels, edit GUEST.INI

     again and change the ASPIPPA3.SYS line to read:

     

               ASPI=ASPIPPA3.SYS SCAN /INFO SL360=NO

     

     Repeat steps 6 through 8 to save the changes to GUEST.INI

     and retest.  If operation is still not normal, restore

     GUEST.INI to its original state.

     Section 4

     Installing Zip Support on DOS-Only Systems

     

     The SETUP.EXE program on the Zip Install floppy disk for

     Windows/DOS runs 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 systems that do not have Windows.

     

     

     ______________________________

     Section 4.1

     Iomega Driver

     

     Running the INSTALL program from the SCSI 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 Iomega SCSI

     Manual which is included on the Install floppy.  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 the Iomega SCSI Manual for

     manual installation instructions.  (See Section 6 in this

     file for detailed instructions on accessing the Iomega SCSI

     Manual.)

     

     NOTE:  Iomega SCSI includes optional CD-ROM support.  Refer

     to Section 7 in this guide for additional information on

     installing the Iomega CD-ROM driver.

     

     

     ______________________________

     Section 4.2

     Zip Tools

     

     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 Iomega SCSI

     Manual.  (See Section 6 in this file for information on

     accessing the Iomega SCSI Manual.)

     Section 5

     Installation Troubleshooting

     

     This section includes problem solving information for the

     following problems:

     

       5.1     Duplicate drive letters

       5.2     No drive letter available for the Zip drive

       5.3     GUEST.EXE cannot locate the Zip drive

       5.4     Other problems

       5.5     Special Information for Users of Adaptec EZ-SCSI

     

     

     _______________________________

     Section 5.1

     Duplicate drive letters

     

     If you see two drive letters for your Zip drive or other

     drive you are using with the Guest driver, 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.

     

     

     ______________________________

     Section 5.2

     No drive letter available for the Zip drive

     

     You may see this problem when using the Guest program.  For

     detailed problem-solving information, refer to the

     GUESTHLP.TXT file which is located on the "Zip Install"

     floppy for Windows/DOS.

     

     

     _____________________________

     Section 5.3

     GUEST.EXE cannot locate the Zip drive

     

     If you run the Guest program and it informs you that no

     drive letters were added, and you cannot access the Zip

     drive, it indicates that the driver is unable to locate the

     Zip drive.  This could be due to a hardware installation

     problem or the result of two or more SCSI host adapters in

     the computer.  For detailed problem-solving information,

     refer to the GUESTHLP.TXT file which is located on the "Zip

     Install" floppy for Windows/DOS.

     

     

     _____________________________

     Section 5.4

     Other problems

     

     If you encounter other problems while installing or using

     Zip Tools software or Iomega SCSI, refer to the Iomega SCSI

     Manual for additional problem solving information.  Section

     6 contains detailed instructions on accessing the Iomega

     SCSI Manual.

     Section 5.5

     Special Information for Users of Adaptec EZ-SCSI



     Zip Tools software and Adaptec EZ-SCSI can be used together

     on the same system without problems; however, you must tell

     the Adaptec ASPIDISK.SYS device driver to control only the

     devices you want it to support.  If you do not specify the

     devices you want ASPIDISK to control, it will take control

     of your Iomega drives and you will be unable to use your Zip

     Tools software.



     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=[...].  For

     example:



               device=c:\scsi\aspidisk.sys /d /pause /id=0+1



     This example would tell the ASPIDISK driver to support the

     devices at SCSI ID 0 and SCSI ID 1 on host adapter #0.  (If

     you computer has one host adapter, it is host adapter #0.)



     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 6

     Electronic Manual

     

     The Zip Install floppy for Windows/DOS includes an

     electronic manual which contains complete installation,

     problem-solving, and reference information for Iomega SCSI

     software.  To access the manual, insert the 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 manual from the Windows File Manager

     by selecting drive A: and double-clicking on MANUAL.EXE.)

     

     After your Zip software is installed, you can access the

     manual from the C:\ZIPTOOLS directory (where C: is the drive

     and \ZIPTOOLS is the directory where your Zip Tools software

     is installed).  (Navigating in the manual or printing from

     the manual will be faster from drive C: than from the

     Install floppy.)  To access the manual, go to the DOS prompt

     and type:

     

               C: <Enter>     

               cd \ZIPTOOLS <Enter>

               MANUAL <Enter>

     

     If you have installed Iomega SCSI software, you can access

     the manual from the C:\IOMEGA directory (where C: is the

     drive and \IOMEGA is the directory where Iomega SCSI is

     installed).

     

     

     _________________________________________________________

     Section 7

     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 "Zip Install" floppy for Windows/DOS

     into the computer's floppy drive.

     

     Step 3.  Run GUEST.EXE from the Install floppy disk.  Note

     the drive letter Guest assigns to your Zip drive.

     

     Step 4.  Run D:\SCSI\INSTALL.EXE where D: is the Zip drive

     letter.

     

     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.

     Cautions

     

     

     ______________________________

     Section 8.1

     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 8.2

     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 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 SCSI directory on the Zip Tools

     disk.  If you use Windows, also install your Zip Tools

     software for Windows by running the Zip Software 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 manual 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 8.3

     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 manual.





     

     _________________________________________________________

     Section 9

     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 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.
