     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.

     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.)
