     Section 1
     What is Guest?
     
     Guest is a portable driver program that lets you use your
     Zip drive on a computer without having to permanently
     install the Iomega driver or Zip Tools software.  There are
     versions of Guest for both Macintosh and PC systems.  Guest
     for IBM-compatible PCs running Windows 3.1 and/or DOS is
     described here.  If you are using Windows 95, refer to "Help
     for Guest95" on the Windows/DOS "Install" floppy.  For
     information on Guest for Macintosh, refer to "Iomega Guest
     Help" on the "Install" floppy for Macintosh.

     When you run GUEST.EXE, it loads into the computer's memory
     and stays there until the computer is rebooted.  While Guest
     is in memory, it tells the computer how to talk to the Zip
     drive and provides the Zip drive with a drive letter.  Guest
     allows you to read files from and write files to your Zip
     disks.

     In addition to the Zip drive, you can use Guest to support
     other Iomega drives, including 5.25 inch Bernoulli drives
     and LaserSafe drives, as well as non-Iomega removable SCSI
     drives, such as SyQuest drives and magneto-optical drives.

     NOTE:  When you install Zip Tools software under Windows
     3.1, it installs the Guest driver program in the computer's
     AUTOEXEC.BAT file so that Guest loads each time the computer
     boots.  For more information, refer to Section 7, "Using
     Guest as a Permanent Driver."

     
     
     _________________________________________________________
     Section 2
     System Requirements for Guest

     To run GUEST.EXE, you need a compatible version of Windows
     and/or DOS.
  
         Compatible versions of Windows include Windows 3.1 or
          3.11, and Windows for Workgroups 3.1 or 3.11.
  
         Compatible versions of DOS include MS-DOS version 4.0
          or higher, PC-DOS version 4.0 or higher, and DR/Novell
          DOS version 6.0 or higher.  To check your version of
          DOS, use the DOS VER command.

     The drive you want Guest to support must be connected to the
     computer before Guest is loaded.  If you are using Guest
     with a Zip drive, the computer must have a compatible
     connection for the Zip drive model you are using.
  
         The Parallel Port model of the Zip drive can be used on
          any IBM-compatible PC with a standard parallel port
          (printer port). 
 
         The SCSI model of the Zip drive requires a SCSI
          connection.  On most IBM-compatible PCs, a SCSI host
          adapter must be installed in the computer to provide a
          SCSI connection.  If the computer has a non-Iomega SCSI
          adapter, check the information under Solving Problems
          in this help file before loading Guest.
     
     
     _________________________________________________________
     Section 3
     How to Load Guest
     
     Use the following procedure to load Guest to run your Zip
     drive:

      1.  Connect the Zip drive to the computer according to the
          instructions in your Zip Installation Guide.

      2.  Insert the "Install" floppy disk for Windows/DOS in the
          computer's floppy drive.

      3.  If you are using Windows, you MUST exit Windows before
          loading Guest.  Select Exit from the Program Manager's
          File menu, and click on OK to end the Windows session.

      4.  At the DOS prompt, type either "a:Guest" (if the
          "Install" floppy is in drive a:), or "b:Guest" (if the
          "Install" floppy is in drive b:), then press the Enter
          key.  If you use Windows, you can restart Windows after
          Guest loads.

     If you encounter any problems, refer to Solving Problems in
     this file.

     Section 4.1
     Loading Guest into Upper Memory
     
     Guest can be loaded into upper memory using the DOS LOADHIGH
     command, provided an expanded memory manager (such as
     EMM386, QEMM, BLUEMAX, or 386MAX) is loaded on the computer. 
     Refer to your DOS User's Guide for detailed information on
     using the LOADHIGH command.
     
     
     ______________________________
     Section 4.2
     Express Loading Guest
     
     Each time the Guest driver loads, it must also load an ASPI
     manager so that it can communicate with the Zip drive
     through the computer's SCSI host adapter or parallel port. 
     To provide Guest with the flexibility to use a variety of
     host adapters, the "Install" floppy for Windows/DOS includes
     a complete set of Iomega ASPI managers.  As Guest loads, it
     tries to load each ASPI manager in turn until it finds one
     that allows it to talk to the Zip drive.

     Guest can load much more quickly if it does not have to use
     this trial-and-error process to find the correct ASPI
     manager.  If you use Guest routinely with one or two
     specific host adapters, you may want to edit the GUEST.INI
     file and remark out the ASPI managers you do not need.  Then
     Guest will try to load only the ASPI managers for the
     adapters you normally use.  

     NOTE:  Guest loads a single ASPI manager each time it runs. 
     The ASPI manager selected will be the first one available in
     the GUEST.INI file that allows the Guest driver to
     communicate with a supported drive. 

     Use the following procedure to customize your GUEST.INI
     file:

     Step 1:  Copy all files on the Zip "Install" floppy for
     Windows/DOS to another disk.
     The "Install" floppy disk is permanently write-protected, so
     in order to edit the GUEST.INI file and use the new file to
     run the Guest program, you must copy the files to another
     disk.  You can copy the files to another floppy disk or to
     the hard disk on the computer where you will be using the
     Guest program.  If you need instructions on copying files,
     refer to the documentation that came with your Windows or
     DOS programs.

     Step 2:  Use a text editor to open the GUEST.INI file.
     Locate the GUEST.INI file on your copy of the "Install"
     floppy disk.  The GUEST.INI file is a text file, so you can
     use the Notepad in Windows, the DOS EDIT program, or any
     other ASCII text editor to edit it.  

     Step 3:  Identify the ASPI manager line Guest needs to load
     to support your Zip drive.
     For example, if you routinely use Guest when your Zip drive
     is connected to an Iomega PC1616 adapter, the Guest program
     needs to load the line that reads "ASPI=ASPI1616.SYS".  Use
     the following table to help you identify the ASPI manager
     line you need to load:

          Iomega Adapter                ASPI Manager

          Zip zoom SCSI accelerator     ASPIPC16.SYS
          parallel port Zip drive       ASPIPPM1.SYS
          PPA-3 adapter                 ASPIPPM1.SYS
          PC1616                        ASPI1616.SYS
          PC1600                        ASPIPC16.SYS
          PC800                         ASPIPC8.SYS
          PC2                           ASPIPC2.SYS
          PC4                           ASPIPC4.SYS

     Step 4:  Remark out each ASPI manager line you do NOT need
     to load by inserting "rem " at the start of the line.
     For the example where Guest is routinely used when the Zip
     drive is connected to an Iomega PC1616 adapter, you would
     remark out all ASPI manager lines except the ASPI1616.SYS
     line:

               rem ASPI=ASPIPPM1.SYS
               ASPI=ASPI1616.SYS
               rem ASPI=ASPIPC16.SYS
               rem ASPI=ASPIPC8.SYS
               rem ASPI=ASPIPC2.SYS
               rem ASPI=ASPIPC4.SYS


     Step 5:  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.

     NOTE:  If you later need to use an ASPI manager which has
     been remarked out, simply edit GUEST.INI again and remove
     the "rem " at the start of the ASPI manager line, or use the
     original Zip "Install" floppy diskette to run Guest.

     ASPI Manager Reference:  Detailed reference information on
     the ASPI managers used by the Guest driver is located in the
     electronic "Installation Manual" (MANUAL.EXE).  You can
     access the manual from the "Install" floppy for Windows/DOS
     by typing:

               A: <Enter>

     _____________________________
     Section 5.1
     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 could be due to a hardware installation
     problem or the result of two or more SCSI host adapters in
     the computer.

     Section 5.1.1
     Solving Hardware Installation Problems

     Guest will not assign a letter to the Zip drive if the data
     cable connections are loose or incorrect, or if the drive is
     not receiving power.  Check the following:

      *  Make sure the Zip drive is correctly connected to the
     computer.  A parallel port model of the Zip drive MUST be
     connected to an IBM-compatible parallel port (printer port). 
     A SCSI model of the Zip drive MUST be connected to a SCSI
     connection (usually provided by a SCSI host adapter on a
     PC).  If the Zip drive is connected to a non-Iomega SCSI
     host adapter, it must be supported by an ASPI manager which
     is installed in the CONFIG.SYS file or the GUEST.INI file. 
     (See "Using Guest with non-Iomega ASPI managers" later in
     this file.)

      *  Make sure the Zip drive is correctly connected to a
     working power supply.  If you have an external Zip drive,
     try disconnecting the power cable from the Zip drive and
     then reconnecting it.  (After reconnecting the power, check
     that the green power light on the front of the external Zip
     drive is ON.)  If you have an internal Zip drive, it must be
     securely connected to a computer power supply cable as
     illustrated in the printed Installation Guide that came with
     the drive. 
  
      *  Make sure all data cable connections are STRAIGHT and
     SECURE.  If you have an external Zip drive, tighten the
     connector screws firmly and evenly on both the connection to
     the Zip drive and to the computer.  (When connecting a
     parallel port Zip drive, the connection to the parallel port
     must be very tight on some computers before the computer
     will recognize the Zip drive!)  If you have an internal Zip
     drive, make sure all Pin 1 connections are correct.  (Refer
     to the printed Installation Guide that came with your drive
     for detailed instructions on connecting cables.)

     Check the Troubleshooting section in your Zip User's Guide
     for a detailed list of problem solving suggestions.  Refer
     to your Zip Installation Guide for complete instructions on
     connecting the Zip drive.  After checking your hardware
     installation, rerun GUEST.EXE.

     If you are using the SCSI model of the Zip drive and two or
     more SCSI adapters are present in the computer, you should
     also check the problem solving information in the next
     section.  If your Zip drive is part of a SCSI chain, make
     sure that each device in the chain has a unique SCSI ID
     number (no duplicates), and that the chain is correctly
     terminated.  Refer to the printed Zip User's Guide that came
     with your drive for more detailed SCSI Guidelines.

     If you are using the parallel port model of the Zip drive
     and the computer still does not recognize the Zip drive
     after you have thoroughly checked the hardware installation,
     the computer's parallel port may not be compatible with the
     Zip drive.  Try  installing the Zip drive on a different
     computer.  If a different computer recognizes the Zip drive,
     the problem is probably an incompatible parallel port.  If
     neither computer recognizes the Zip drive, contact Iomega
     Customer Service.  Refer to the electronic "Installation
     Manual" (MANUAL.EXE) for a complete list of support numbers. 
     You can access the manual from the "Install" floppy for
     Windows/DOS by typing:

               A: <Enter>
               MANUAL <Enter>


     Section 5.1.2
     Two or More SCSI Adapters

     The Guest program may be unable to assign a drive letter to
     the Zip drive when there are two or more SCSI host adapters
     in the computer.  To solve this problem, you need to edit
     the GUEST.INI file which is located on the "Install" floppy
     for Windows/DOS, and specify which ASPI manager Guest needs
     to use to access the Zip drive.

     Use the following procedure:

     Step 1:  Copy all files on the Zip "Install" floppy for
     Windows/DOS to another disk.
     The "Install" floppy disk is permanently write-protected, so
     in order to edit the GUEST.INI file and use the new file to
     run the Guest program, you must copy the files to another
     disk.  You can copy the files to another floppy disk or to
     the hard disk on the computer where you will be using the
     Guest program.  If you need instructions on copying files,
     refer to the documentation that came with your Windows or
     DOS programs.

     Step 2:  Use a text editor to open the GUEST.INI file.
     Locate the GUEST.INI file on your copy of the "Install"
     floppy disk.  The GUEST.INI file is a text file, so you can
     use the Notepad in Windows, the DOS EDIT program, or any
     other ASCII text editor to edit it.  

     Step 3:  Locate the ASPI manager line for the SCSI host
     adapter being used by the Zip drive.
     For example, if your Zip drive is connected to an Iomega
     PC1600 adapter, the Guest program needs to load the line
     that reads "ASPI=ASPIPC16.SYS".  Use the following table to
     help you identify the correct ASPI manager line:

          Iomega Adapter                ASPI Manager

          Zip zoom SCSI accelerator     ASPIPC16.SYS
          parallel port Zip drive       ASPIPPM1.SYS
          PPA-3 adapter                 ASPIPPM1.SYS
          PC1616                        ASPI1616.SYS
          PC1600                        ASPIPC16.SYS
          PC800                         ASPIPC8.SYS
          PC2                           ASPIPC2.SYS
          PC4                           ASPIPC4.SYS

     Step 4:  Remark out the ASPI manager lines not needed for
     the Zip drive by inserting "rem " at the start of each line.
     For example, if your Zip drive is connected to an Iomega
     PC1600 adapter, you would need to remark out all ASPI
     manager lines EXCEPT the ASPIPC16.SYS line:

               rem ASPI=ASPIPPM1.SYS
               rem ASPI=ASPI1616.SYS
               ASPI=ASPIPC16.SYS
               rem ASPI=ASPIPC8.SYS
               rem ASPI=ASPIPC2.SYS
               rem ASPI=ASPIPC4.SYS


     Step 5:  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 6:  Rerun the Setup program from your edited copy of
     the Install floppy disk.

     NOTE:  If you later need to install Zip Tools software on a
     different computer, use the original Zip "Install" floppy
     diskette.

     ASPI Manager Reference:  Detailed reference information on
     the ASPI managers used by the Guest driver is located in the
     electronic "Installation Manual" (MANUAL.EXE).  You can
     access the manual from the "Install" floppy for Windows/DOS
     by typing:

               A: <Enter>
               MANUAL <Enter>
     
     
     _______________________________
     Section 5.2
     Duplicate drive letters
     
     If you see two drive letters for your Zip drive or other
     drive you are using with 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 GUEST.EXE.  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 5.3
     No drive letter available for the Zip drive
     
     If all drive letters available for physical drives are in
     use on the system, GUEST.EXE will be unable to assign a
     drive letter for the Zip drive (or other drive you are
     connecting with Guest).  Use the DOS LASTDRIVE command in
     the computer's CONFIG.SYS file to increase the number of
     physical drive letters.  For example, adding the statement
     LASTDRIVE=M to CONFIG.SYS will provide drive letters for ten
     additional drives after drive C.  Use the following
     procedure to edit the CONFIG.SYS file:

     Step 1:  Use a text editor to open the CONFIG.SYS file.
     You can use the Notepad in Windows, the DOS EDIT program, or
     any other ASCII text editor.  The CONFIG.SYS file is a text
     file located in the root directory on the computer's boot
     drive (C:).
     
     Step 2:  Add the following line to the end of the CONFIG.SYS
     file.
     
               LASTDRIVE=m 
     
     This will provide ten additional drive letters for any new
     drives you want to add to your system, including your Zip
     drive.  If you do not need all of the drive letters between
     d: and m: for physical drives, you can use a letter earlier
     in the alphabet in place of the letter m; however, make sure
     you provide enough drive letters after e: to accommodate
     your Zip drive and any other drives you may add to your
     system.  If your CONFIG.SYS file already has a LASTDRIVE
     line, change the last drive letter to a letter further down
     the alphabet.  Do not set the last drive letter to a letter
     late in the alphabet, such as X, Y, or Z.
     
     Step 3:  Save the changes to the CONFIG.SYS file and exit
     the text editor.  If you are using an editor that has a
     variety of file formats, be sure to save the CONFIG.SYS file
     as ASCII text or DOS text.
     
     Step 4:  Reboot the computer.
     Load GUEST.EXE after the computer boots.  
     
     NETWORK USERS:  You may have to relocate your network drive
     letter.  Ask your network administrator for help, or refer
     to the following instructions:
  
     Your first network drive letter will be the letter following
     the one used in the LASTDRIVE statement in your CONFIG.SYS
     file.  For example, if you used LASTDRIVE=m, the first
     network drive letter will be N.
     
     If your network drive letter has changed, applications you
     are running from the network (such as Windows or other
     applications that reference specific drive letters) may fail
     to work correctly unless they are reinstalled or adjusted
     for the drive letter change.  If you use a batch file to
     connect to the network, it will need to be adjusted to the
     new drive letter.  Your network login script may need to be
     revised if it refers to a specific drive letter for your
     network drive.
     
     Check the following:
     
      *  Edit the Path statement in your AUTOEXEC.BAT file to
     correctly reference your new network drive letter.
     
      *  Edit any batch files which load shells or applications
     from a network (including AUTOEXEC.BAT) to correctly
     reference new drive letter assignments.
     
      *  Edit your Windows "INI" files and your Windows groups to
     correctly reference your new drive letters.
     
      *  Check other application setup files.  Rerun the setup if
     drive letters cannot be edited.
     
      *  Check your user login script for references to specific
     network drive letters.  
     
     Reboot your computer and check your applications. 
     Applications that do not work with the new drive letter may
     need to be reinstalled.
     
     
     _____________________________
     Section 5.4
     Using Guest with non-Iomega ASPI managers

     The Guest driver utilizes ASPI managers to communicate with
     drives connected through a SCSI host adapter.  The "Install"
     floppy for Windows/DOS includes a set of ASPI managers for
     Iomega adapters.  If you are using a non-Iomega host adapter
     and ASPI manager software, you may need to edit the
     GUEST.INI file and add a line for the non-Iomega ASPI
     manager.  (If the adapter does not have an ASPI manager,
     Guest will not be able to operate.)

     Use the following procedure to edit the GUEST.INI file:
     
     Step 1:  Copy all files on the Zip "Install" floppy for
     Windows/DOS to another disk.
     The "Install" floppy disk is permanently write-protected, so
     in order to edit the GUEST.INI file and use the new file to
     run the Guest program, you must copy the files to another
     disk.  You can copy the files to another floppy disk or to
     the hard disk on the computer where you will be using the
     Guest program.  If you need instructions on copying files,
     refer to the documentation that came with your Windows or
     DOS programs.

     Step 2:  Use a text editor to open the GUEST.INI file.
     Locate the GUEST.INI file on your copy of the Zip Install
     floppy disk.  The GUEST.INI file is a text file, so you can
     use the Notepad in Windows, the DOS EDIT program, or any
     other ASCII text editor to edit it.  

     Step 3:  Add a command line for the non-Iomega ASPI manager.
     Use the following syntax:  
     
     ASPI=<full path for ASPI manager><ASPI manager filename>
     
     The following line is an example for an ASPI2DOS ASPI
     manager which is located in the directory C:\ASPI:
     
               ASPI=C:\ASPI\ASPI2DOS.SYS
     
     If you do not know the path or filename for the non-Iomega
     ASPI manager, refer to the documentation that came with the
     adapter or ASPI software.
     
     Step 4:  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 5: Use your edited copy of the "Install" floppy disk to
     run the Guest program.

     ASPI Manager Reference:  Detailed reference information on
     the ASPI managers included with the Guest driver is located
     in the electronic "Installation Manual" (MANUAL.EXE).  You
     can access the manual from the "Install" floppy for
     Windows/DOS by typing:

               A: <Enter>
               MANUAL <Enter>


     _____________________________
     Section 5.5
     Drive C: no longer accessible

     If you are booting from an Iomega PC1600 or Adaptec adapter,
     the ASPI manager for the adapter must be installed in the
     computer's CONFIG.SYS file before GUEST.EXE is run.  If the
     ASPI manager is not installed in CONFIG.SYS when GUEST.EXE
     is run, Guest will load the ASPI manager via the GUEST.INI
     file, which will cause drive C: to no longer be accessible.  

     NOTE:  The ASPI manager for the bootable adapter must be
     loaded before any other ASPI managers in the CONFIG.SYS
     file.  If you need information on installing ASPI managers,
     refer to the electronic "Installation Manual" (MANUAL.EXE). 
     You can access the manual from the "Install" floppy for
     Windows/DOS by typing:

               A: <Enter>
               MANUAL <Enter>


     
     _________________________________________________________
     Section 6
     Required Files for Using Guest
     
     All of the files needed to load Guest are present on the
     "Install" floppy for Windows/DOS.  If you create additional
     floppies for loading Guest, make sure you include the
     following files:

               GUEST.EXE
               GUEST.INI
               ASPIPPM1.SYS
               ASPI1616.SYS
               ASPIPC16.SYS
               ASPIPC8.SYS
               ASPIPC2.SYS
               ASPIPC4.SYS

     Refer to Section 4.2, "Express Loading Guest," for
     instructions on customizing the GUEST.INI file to minimize
     the time it takes to load Guest.

     Section 7
     Using Guest as a Permanent Driver

     The Guest program, GUEST.EXE, is also the permanent driver
     program for the Zip drive under Windows 3.1/DOS.  If you
     install Zip Tools software using the Setup program on the
     "Install" floppy disk for Windows/DOS, it automatically
     installs GUEST.EXE in the computer's AUTOEXEC.BAT file. 
     This causes GUEST.EXE to run each time the computer boots. 
     If Guest can locate a Zip drive (or other supported drive),
     it loads into the computer's memory and assigns the Zip
     drive a drive letter.  If Guest cannot locate a supported
     drive, it does not load.

     If you use the Guest program frequently on a particular
     computer, you may want to install GUEST.EXE as a permanent
     driver on that computer.  If Windows is installed on the
     computer, the easiest way to permanently install Guest is by
     using the Setup program on the "Install" floppy disk.  If
     desired, you can select to install only the driver.

     To run the Setup program, insert the "Install" floppy disk
     into the computer's floppy drive.  Load Windows and choose
     "Run" from the Program Manager's File menu.  In the Command
     Line box, type either "a:setup" (if the "Install" floppy is
     in drive a:) or "b:setup" (if the "Install" floppy is in
     drive b:), then click on "OK" or press the Enter key.

     If the computer does not have Windows, you can manually
     install GUEST.EXE in the computer's AUTOEXEC.BAT file.  For
     a detailed manual installation procedure,refer to the
     electronic "Installation Manual" (MANUAL.EXE) located on the
     "Install" floppy.
